How to Write a Literature Review | Guide, Examples, & Templates
Published on January 2, 2023 by Shona McCombes . Revised on September 11, 2023.
What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .
There are five key steps to writing a literature review:
- Search for relevant literature
- Evaluate sources
- Identify themes, debates, and gaps
- Outline the structure
- Write your literature review
A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:
- Demonstrate your familiarity with the topic and its scholarly context
- Develop a theoretical framework and methodology for your research
- Position your work in relation to other researchers and theorists
- Show how your research addresses a gap or contributes to a debate
- Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.
Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Prevent plagiarism. Run a free check.
Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.
- Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
- Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
- Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
- Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .
If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .
Make a list of keywords
Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.
- Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
- Body image, self-perception, self-esteem, mental health
- Generation Z, teenagers, adolescents, youth
Search for relevant sources
Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:
- Your university’s library catalogue
- Google Scholar
- Project Muse (humanities and social sciences)
- Medline (life sciences and biomedicine)
- EconLit (economics)
- Inspec (physics, engineering and computer science)
You can also use boolean operators to help narrow down your search.
Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.
You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.
For each publication, ask yourself:
- What question or problem is the author addressing?
- What are the key concepts and how are they defined?
- What are the key theories, models, and methods?
- Does the research use established frameworks or take an innovative approach?
- What are the results and conclusions of the study?
- How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
- What are the strengths and weaknesses of the research?
Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.
You can use our template to summarize and evaluate sources you’re thinking about using. Click on either button below to download.
Take notes and cite your sources
As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.
It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:
- Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
- Themes: what questions or concepts recur across the literature?
- Debates, conflicts and contradictions: where do sources disagree?
- Pivotal publications: are there any influential theories or studies that changed the direction of the field?
- Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?
This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.
- Most research has focused on young women.
- There is an increasing interest in the visual aspects of social media.
- But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.
There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).
Chronological
The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.
Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.
If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.
For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.
Methodological
If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:
- Look at what results have emerged in qualitative versus quantitative research
- Discuss how the topic has been approached by empirical versus theoretical scholarship
- Divide the literature into sociological, historical, and cultural sources
Theoretical
A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.
You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.
Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.
The introduction should clearly establish the focus and purpose of the literature review.
Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.
As you write, you can follow these tips:
- Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
- Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
- Critically evaluate: mention the strengths and weaknesses of your sources
- Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts
In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .
It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.
There are several reasons to conduct a literature review at the beginning of a research project:
- To familiarize yourself with the current state of knowledge on your topic
- To ensure that you’re not just repeating what others have already done
- To identify gaps in knowledge and unresolved problems that your research can address
- To develop your theoretical framework and methodology
- To provide an overview of the key findings and debates on the topic
Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.
The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .
A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other academic texts , with an introduction , a main body, and a conclusion .
An annotated bibliography is a list of source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a paper .

- A Guide to Writing a PhD Literature Review
Written by Ben Taylor
Most PhD projects begin with a literature review, which usually serves as the first chapter of your dissertation. This provides an opportunity for you to show that you understand the body of academic work that has already been done in relation to your topic, including books, articles, data and research papers.
You should be prepared to offer your own critical analysis of this literature, as well as illustrating where your own research lies within the field – and how it contributes something new / significant to your subject.
This page will give you an overview of what you need to know about writing a literature review, with detail on structure, length and conclusions.
On this page
What is a phd literature review.
A literature review is usually one of the first things you’ll do after beginning your PhD . Once you’ve met with your supervisor and discussed the scope of your research project, you’ll conduct a survey of the scholarly work that’s already been done in your area.
Depending on the nature of your PhD, this work could comprise books, publications, articles, experimental data and more. This body of work is collectively known as the ‘scholarly literature’, on your subject. You won’t have to tackle any novels, poetry or drama during this review (unless, of course, you’re actually studying a PhD in English Literature, in which case that comes later).
The purpose of the PhD literature review isn’t just to summarise what other scholars have done before you. You should analyse and evaluate the current body of work , situating your own research within that context and demonstrating the significant original contribution your research will make.
Planning your PhD literature review
Your supervisor will be able to give you advice if you’re not quite sure where to begin your review, pointing you in the direction of key texts and research that you can then investigate. It’s worth paying attention to the bibliographies (and literature reviews!) of these publications, which can often lead you towards even more specialist texts that could prove invaluable in your research. At the same time, it’s important not to let yourself fall down an academic rabbit hole – make sure that the books and articles you’re surveying are genuinely relevant to your own project.
You should aim to include a broad range of literature in your review, showing the scope of your knowledge, from foundational texts to the most recent publications.
The note-taking process is crucial while you’re in the early stages of your literature review. Keep a clear record of the sources you’ve read, along with your critical analysis of their key arguments and what you think makes them relevant to your research project.
How long should a literature review be?
The length of a PhD literature review varies greatly by subject. In Arts, Humanities and Social Sciences the review will typically be around 5,000 words long, while STEM literature reviews will usually be closer to 10,000 words long. In any case, you should consult with your supervisor on the optimum length for your own literature review.
Structuring a PhD literature review
When you begin to write your PhD literature review, it’s important to have a clear idea of its outline. Roughly speaking, the literature review structure should:
- Introduce your topic and explain its significance
- Evaluate the existing literature with reference to your thesis
- Give a conclusion that considers the implications of your research for future study
The main body of your literature review will be spent critiquing the existing work that scholars have done in your field. There are a few different ways you may want to structure this part of the review, depending on the subject and the nature of your dissertation:
- Chronologically – If your research looks at how something has changed over time, it may make sense to review the literature chronologically, tracking the way that ideas, attitudes and theories have shifted. This might seem like quite a simple way to structure the review, but it’s also imperative to identify the common threads and sticking points between academics along the way, rather than merely reeling off a list of books and articles.
- Thematically – If your dissertation encompasses several different themes, you might want to group the literature by these subjects, while also emphasising the connections between them.
- Methodologically – If you are going to be working with experimental data or statistics, it could be a good idea to assess the different methods that previous scholars have used in your field to produce relevant literature.
Whichever technique you use to structure your literature review, you should take care not to simply list different books, articles and research papers without offering your own commentary.
Always highlight the similarities (and differences) between them, giving your analysis of the significance of these relationships, connections and contrasts.
Writing up a PhD literature review
The process of writing a literature review is different to that of writing the bulk of the dissertation itself. The aim at this point isn’t necessarily to illustrate your own original ideas and research – that’s what the dissertation is for – but rather to show the depth of your knowledge of the field and your ability to assess the work of other scholars . It’s also an opportunity for you to indicate exactly how your dissertation will make an original contribution to your subject area.
These are some tips to bear in mind when writing a literature review:
- Avoid paraphrasing – instead, offer your own evaluation of a source and its assertions
- Follow a logical path from one source or theme to the next – don’t make leaps between different books or articles without explaining the connection between them
- Critically analyse the literature – challenge assumptions, assess the validity of argument and write with authority
- Don’t be too broad in your scope – it can be easy to get carried away including every piece of related literature you come across, but it’s also important not to let your review become too sprawling or rambling
The fact that you usually begin your literature review right at the start of a PhD means that it’s likely you’ll come across plenty more relevant books and papers during the course of your research and while writing the dissertation. So, it’s useful to think of this first draft as a work-in-progress that you keep up-to-date as you write your thesis.
Finishing a PhD literature review
As you come to the end of your dissertation, it’s vital to take a close look at your initial literature review and make sure that it’s consistent with the conclusions that you’ve reached. Of course, a lot can change over the course of a PhD so it’s entirely possible that your research led you in a different direction than you imagined at the beginning.
The conclusion of your literature review should summarise the significance of the survey that you’ve just completed, explaining its relevance for the research your dissertation will undertake.
Literature reviews and PhD upgrade exams
The literature review is usually one of the first sections of a PhD to be completed, at least in its draft form. As such, it is often part of the material that you may submit for your PhD upgrade exam . This usually takes place at the end of your first year (though not all PhDs require it). Involves you discussing your work so far with academics in your department to confirm that your project is on track for a PhD. The feedback you get at this point may help shape your literature review, or reveal any areas you’ve missed.

Writing a Literature Review

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.
Where, when, and why would I write a lit review?
There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.
A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.
Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.
What are the parts of a lit review?
Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.
Introduction:
- An introductory paragraph that explains what your working topic and thesis is
- A forecast of key topics or texts that will appear in the review
- Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
- Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
- Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
- Critically Evaluate: Mention the strengths and weaknesses of your sources
- Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.
Conclusion:
- Summarize the key findings you have taken from the literature and emphasize their significance
- Connect it back to your primary research question
How should I organize my lit review?
Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:
- Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
- Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
- Qualitative versus quantitative research
- Empirical versus theoretical scholarship
- Divide the research by sociological, historical, or cultural sources
- Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.
What are some strategies or tips I can use while writing my lit review?
Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .
As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.
Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:
- It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
- Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
- Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
- Read more about synthesis here.
The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

In this article, I’ll give you detailed instructions for how to write the literature review of your dissertation without stress. I’ll also provide a sample outline.

Though technically Chapter 2 of your dissertation, many students write their literature review first. Why? Because having a solid foundation in the research informs the way you write Chapter 1.
Also, when writing Chapter 1, you’ll need to become familiar with the literature anyway. It only makes sense to write down what you learn to form the start of your lit review.
Some institutions even encourage students to write Chapter 2 first. But it’s important to talk with your Chair to see what he or she recommends.
How Long Should a Literature Review Be?
There is no set length for a literature review. The length largely depends on your area of study. However, I have found that most literature reviews are between 40-60 pages.
If your literature review is significantly shorter than that, ask yourself (a) if there is other relevant research that you have not explored, or (b) if you have provided enough of a discussion about the information you did explore.
Preparing to Write the Literature Review for your Dissertation
![how to write a literature review for a phd dissertation barefoot woman sitting on a large stack of books](https://www.beyondphdcoaching.com/wp-content/uploads/2019/01/gaelle-marcel-8992-unsplash-684x1024.jpg)
Step 1. Search Using Key Terms
Most people start their lit review searching appropriate databases using key terms. For example, if you’re researching the impact of social media on adult learning, some key terms you would use at the start of your search would be adult learning, androgogy, social media, and “learning and social media” together.
If your topic was the impact of natural disasters on stock prices, then you would need to explore all types of natural disasters, other market factors that impact stock prices, and the methodologies used.
You can save time by skimming the abstracts first; if the article is not what you thought it might be you can move on quickly.
![title= how to write a literature review for a phd dissertation](https://www.beyondphdcoaching.com/wp-content/uploads/2024/01/Frame-43757.png)
Once you start finding articles using key terms, two different things will usually happen: you will find new key terms to search, and the articles will lead you directly to other articles related to what you are studying. It becomes like a snowball rolling downhill.
Note that the vast majority of your sources should be articles from peer-reviewed journals.
Step 2. Immerse Yourself in the Literature
![how to write a literature review for a phd dissertation woman asleep on the couch next to a giant pile of books](https://www.beyondphdcoaching.com/wp-content/uploads/2019/07/AdobeStock_259829489-1024x678.jpeg)
When people ask what they should do first for their dissertation the most common answer is “immerse yourself in the literature.” What exactly does this mean?
Think of this stage as a trip into the quiet heart of the forest. Your questions are at the center of this journey, and you’ll need to help your reader understand which trees — which particular theories, studies, and lines of reasoning — got you there.
There are lots of trees in this particular forest, but there are particular trees that mark your path. What makes them unique? What about J’s methodology made you choose that study over Y’s? How did B’s argument triumph over A’s, thus leading you to C’s theory?
You are showing your reader that you’ve fully explored the forest of your topic and chosen this particular path, leading to these particular questions (your research questions), for these particular reasons.
Step 3. Consider Gaps in the Research
The gaps in the research are where current knowledge ends and your study begins. In order to build a case for doing your study, you must demonstrate that it:
- Is worthy of doctoral-level research, and
- Has not already been studied
Defining the gaps in the literature should help accomplish both aims. Identifying studies on related topics helps make the case that your study is relevant, since other researchers have conducted related studies.
And showing where they fall short will help make the case that your study is the appropriate next step. Pay special attention to the recommendations for further research that the authors of studies make.
Step 4. Organize What You Find
As you find articles, you will have to come up with methods to organize what you find.
Whether you find a computer-based system (three popular systems are Zotero, endNote, and Mendeley) or some sort of manual system such as index cards, you need to devise a method where you can easily group your references by subject and methodology and find what you are looking for when you need it. It is very frustrating to know you have found an article that supports a point that you are trying to make, but you can’t find the article!
![how to write a literature review for a phd dissertation focused woman studying inside a bright library](https://www.beyondphdcoaching.com/wp-content/uploads/2019/06/AdobeStock_126229177-1024x683.jpeg)
One way to save time and keep things organized is to cut and paste relevant quotations (and their references) under topic headings. You’ll be able to rearrange and do some paraphrasing later, but if you’ve got the quotations and the citations that are important to you already embedded in your text, you’ll have an easier time of it.
If you choose this method, be sure to list the whole reference on the reference/bibliography page so you don’t have to do this page separately later. Some students use Scrivener for this purpose, as it offers a clear way to view and easily navigate to all sections of a written document.

How to Write the Literature Review for your Dissertation
Once you have gathered a sufficient number of pertinent references, you’ll need to string them together in a way that tells your story. Explain what previous researchers have done by telling the story of how knowledge on this topic has evolved. Here, you are laying the support for your topic and showing that your research questions need to be answered. Let’s dive into how to actually write your dissertation’s literature review.
Step 1. Create an Outline
If you’ve created a system for keeping track of the sources you’ve found, you likely already have the bones of an outline. Even if not, it may be relatively easy to see how to organize it all. The main thing to remember is, keep it simple and don’t overthink it. There are several ways to organize your dissertation’s literature review, and I’ll discuss some of the most common below:
- By topic. This is by far the most common approach, and it’s the one I recommend unless there’s a clear reason to do otherwise. Topics are things like servant leadership, transformational leadership, employee retention, organizational knowledge, etc. Organizing by topic is fairly simple and it makes sense to the reader.
- Chronologically. In some cases, it makes sense to tell the story of how knowledge and thought on a given subject have evolved. In this case, sub-sections may indicate important advances or contributions.
- By methodology. Some students organize their literature review by the methodology of the studies. This makes sense when conducting a mixed-methods study, and in cases where methodology is at the forefront.
Step 2. Write the Paragraphs
I said earlier that I thought the lit review was the easiest part to write, and here is why. When you write about the findings of others, you can do it in small, discrete time periods. You go down the path awhile, then you rest.
Once you have many small pieces written, you can then piece them together. You can write each piece without worrying about the flow of the chapter; that can all be done at the end when you put the jigsaw puzzle of references together.
Step 3. Analyze
![how to write a literature review for a phd dissertation woman with curly hair studying in her home office](https://www.beyondphdcoaching.com/wp-content/uploads/2019/07/AdobeStock_225778258-1024x540.jpeg)
The literature review is a demonstration of your ability to think critically about existing research and build meaningfully on it in your study. Avoid simply stating what other researchers said. Find the relationships between studies, note where researchers agree and disagree, and– especiallyy–relate it to your own study.
Pay special attention to controversial issues, and don’t be afraid to give space to researchers who you disagree with. Including differing opinions will only strengthen the credibility of your study, as it demonstrates that you’re willing to consider all sides.
Step 4. Justify the Methodology
In addition to discussing studies related to your topic, include some background on the methodology you will be using. This is especially important if you are using a new or little-used methodology, as it may help get committee members onboard.
I have seen several students get slowed down in the process trying to get committees to buy into the planned methodology. Providing references and samples of where the planned methodology has been used makes the job of the committee easier, and it will also help your reader trust the outcomes.
Advice for Writing Your Dissertation’s Literature Review
- Remember to relate each section back to your study (your Problem and Purpose statements).
- Discuss conflicting findings or theoretical positions. Avoid the temptation to only include research that you agree with.
- Sections should flow together, the way sections of a chapter in a nonfiction book do. They should relate to each other and relate back to the purpose of your study. Avoid making each section an island.
- Discuss how each study or theory relates to the others in that section.
- Avoid relying on direct quotes–you should demonstrate that you understand the study and can describe it accurately.
Sample Outline of a Literature Review (Dissertation Chapter 2)
![how to write a literature review for a phd dissertation close-up shot of an open notebook and a laptop](https://www.beyondphdcoaching.com/wp-content/uploads/2019/07/nick-morrison-FHnnjk1Yj7Y-unsplash-1024x768.jpg)
Here is a sample outline, with some brief instructions. Note that your institution probably has specific requirements for the structure of your dissertation’s literature review. But to give you a general idea, I’ve provided a sample outline of a dissertation ’s literature review here.
- Introduction
- State the problem and the purpose of the study
- Give a brief synopsis of literature that establishes the relevance of the problem
- Very briefly summarize the major sections of your chapter
Documentation of Literature Search Strategy
- Include the library databases and search engines you used
- List the key terms you used
- Describe the scope (qualitative) or iterative process (quantitative). Explain why and based on what criteria you selected the articles you did.
Literature Review (this is the meat of the chapter)
![title= how to write a literature review for a phd dissertation](https://www.beyondphdcoaching.com/wp-content/uploads/2024/01/g12-3.webp)
- Sub-topic a
- Sub-topic b
- Sub-topic c
See below for an example of what this outline might look like.
How to Write a Literature Review for a Dissertation: An Example
Let’s take an example that will make the organization, and the outline, a little bit more clear. Below, I’ll fill out the example outline based on the topics discussed.
If your questions have to do with the impact of the servant leadership style of management on employee retention, you may want to saunter down the path of servant leadership first, learning of its origins , its principles , its values , and its methods .
You’ll note the different ways the style is employed based on different practitioners’ perspectives or circumstances and how studies have evaluated these differences. Researchers will draw conclusions that you’ll want to note, and these conclusions will lead you to your next questions.
![how to write a literature review for a phd dissertation man browsing on his laptop](https://www.beyondphdcoaching.com/wp-content/uploads/2019/07/bench-accounting-C3V88BOoRoM-unsplash-1024x684.jpg)
Next, you’ll want to wander into the territory of management styles to discover their impact on employee retention in general. Does management style really make a difference in employee retention, and if so, what factors, exactly, make this impact?
Employee retention is its own path, and you’ll discover factors, internal and external, that encourage people to stick with their jobs.
You’ll likely find paradoxes and contradictions in here that just bring up more questions. How do internal and external factors mix and match? How can employers influence both psychology and context ? Is it of benefit to try and do so?
At first, these three paths seem somewhat remote from one another, but your interest is where the three converge. Taking the lit review section by section like this before tying it all together will not only make it more manageable to write but will help you lead your reader down the same path you traveled, thereby increasing clarity.
Example Outline
So the main sections of your literature review might look something like this:
- Literature Search Strategy
- Conceptual Framework or Theoretical Foundation
- Literature that supports your methodology
- Origins, principles, values
- Seminal research
- Current research
- Management Styles’ Impact on employee retention
- Internal Factors
- External Factors
- Influencing psychology and context
- Summary and Conclusion
Final Thoughts on Writing Your Dissertation’s Chapter 2
The lit review provides the foundation for your study and perhaps for your career. Spend time reading and getting lost in the literature. The “aha” moments will come where you see how everything fits together.
At that point, it will just be a matter of clearly recording and tracing your path, keeping your references organized, and conveying clearly how your research questions are a natural evolution of previous work that has been done.

How to write a superb literature review

Literature reviews are important resources for scientists. They provide historical context for a field while offering opinions on its future trajectory. Creating them can provide inspiration for one’s own research, as well as some practice in writing. But few scientists are trained in how to write a review — or in what constitutes an excellent one. Even picking the appropriate software to use can be an involved decision (see ‘Tools and techniques’). So Nature asked editors and working scientists with well-cited reviews for their tips.
WENTING ZHAO: Be focused and avoid jargon
Assistant professor of chemical and biomedical engineering, Nanyang Technological University, Singapore.
When I was a research student, review writing improved my understanding of the history of my field. I also learnt about unmet challenges in the field that triggered ideas.
For example, while writing my first review 1 as a PhD student, I was frustrated by how poorly we understood how cells actively sense, interact with and adapt to nanoparticles used in drug delivery. This experience motivated me to study how the surface properties of nanoparticles can be modified to enhance biological sensing. When I transitioned to my postdoctoral research, this question led me to discover the role of cell-membrane curvature, which led to publications and my current research focus. I wouldn’t have started in this area without writing that review.
![how to write a literature review for a phd dissertation](https://media.nature.com/w400/magazine-assets/d41586-020-03422-x/d41586-020-03422-x_17947370.jpg)

A common problem for students writing their first reviews is being overly ambitious. When I wrote mine, I imagined producing a comprehensive summary of every single type of nanomaterial used in biological applications. It ended up becoming a colossal piece of work, with too many papers discussed and without a clear way to categorize them. We published the work in the end, but decided to limit the discussion strictly to nanoparticles for biological sensing, rather than covering how different nanomaterials are used in biology.
My advice to students is to accept that a review is unlike a textbook: it should offer a more focused discussion, and it’s OK to skip some topics so that you do not distract your readers. Students should also consider editorial deadlines, especially for invited reviews: make sure that the review’s scope is not so extensive that it delays the writing.
A good review should also avoid jargon and explain the basic concepts for someone who is new to the field. Although I trained as an engineer, I’m interested in biology, and my research is about developing nanomaterials to manipulate proteins at the cell membrane and how this can affect ageing and cancer. As an ‘outsider’, the reviews that I find most useful for these biological topics are those that speak to me in accessible scientific language.

BOZHI TIAN: Have a process and develop your style
Associate professor of chemistry, University of Chicago, Illinois.
In my lab, we start by asking: what is the purpose of this review? My reasons for writing one can include the chance to contribute insights to the scientific community and identify opportunities for my research. I also see review writing as a way to train early-career researchers in soft skills such as project management and leadership. This is especially true for lead authors, because they will learn to work with their co-authors to integrate the various sections into a piece with smooth transitions and no overlaps.
After we have identified the need and purpose of a review article, I will form a team from the researchers in my lab. I try to include students with different areas of expertise, because it is useful to get a variety of perspectives. For example, in the review ‘An atlas of nano-enabled neural interfaces’ 2 , we had authors with backgrounds in biophysics, neuroengineering, neurobiology and materials sciences focusing on different sections of the review.
After this, I will discuss an outline with my team. We go through multiple iterations to make sure that we have scanned the literature sufficiently and do not repeat discussions that have appeared in other reviews. It is also important that the outline is not decided by me alone: students often have fresh ideas that they can bring to the table. Once this is done, we proceed with the writing.
I often remind my students to imagine themselves as ‘artists of science’ and encourage them to develop how they write and present information. Adding more words isn’t always the best way: for example, I enjoy using tables to summarize research progress and suggest future research trajectories. I’ve also considered including short videos in our review papers to highlight key aspects of the work. I think this can increase readership and accessibility because these videos can be easily shared on social-media platforms.
ANKITA ANIRBAN: Timeliness and figures make a huge difference
Editor, Nature Reviews Physics .
One of my roles as a journal editor is to evaluate proposals for reviews. The best proposals are timely and clearly explain why readers should pay attention to the proposed topic.
It is not enough for a review to be a summary of the latest growth in the literature: the most interesting reviews instead provide a discussion about disagreements in the field.
![how to write a literature review for a phd dissertation](https://media.nature.com/w400/magazine-assets/d41586-020-03422-x/d41586-020-03422-x_17834270.jpg)

Scientists often centre the story of their primary research papers around their figures — but when it comes to reviews, figures often take a secondary role. In my opinion, review figures are more important than most people think. One of my favourite review-style articles 3 presents a plot bringing together data from multiple research papers (many of which directly contradict each other). This is then used to identify broad trends and suggest underlying mechanisms that could explain all of the different conclusions.
An important role of a review article is to introduce researchers to a field. For this, schematic figures can be useful to illustrate the science being discussed, in much the same way as the first slide of a talk should. That is why, at Nature Reviews, we have in-house illustrators to assist authors. However, simplicity is key, and even without support from professional illustrators, researchers can still make use of many free drawing tools to enhance the value of their review figures.

YOOJIN CHOI: Stay updated and be open to suggestions
Research assistant professor, Korea Advanced Institute of Science and Technology, Daejeon.
I started writing the review ‘Biosynthesis of inorganic nanomaterials using microbial cells and bacteriophages’ 4 as a PhD student in 2018. It took me one year to write the first draft because I was working on the review alongside my PhD research and mostly on my own, with support from my adviser. It took a further year to complete the processes of peer review, revision and publication. During this time, many new papers and even competing reviews were published. To provide the most up-to-date and original review, I had to stay abreast of the literature. In my case, I made use of Google Scholar, which I set to send me daily updates of relevant literature based on key words.
Through my review-writing process, I also learnt to be more open to critiques to enhance the value and increase the readership of my work. Initially, my review was focused only on using microbial cells such as bacteria to produce nanomaterials, which was the subject of my PhD research. Bacteria such as these are known as biofactories: that is, organisms that produce biological material which can be modified to produce useful materials, such as magnetic nanoparticles for drug-delivery purposes.
![how to write a literature review for a phd dissertation](https://media.nature.com/w400/magazine-assets/d41586-020-03422-x/d41586-020-03422-x_18649438.jpg)
Synchronized editing: the future of collaborative writing
However, when the first peer-review report came back, all three reviewers suggested expanding the review to cover another type of biofactory: bacteriophages. These are essentially viruses that infect bacteria, and they can also produce nanomaterials.
The feedback eventually led me to include a discussion of the differences between the various biofactories (bacteriophages, bacteria, fungi and microalgae) and their advantages and disadvantages. This turned out to be a great addition because it made the review more comprehensive.
Writing the review also led me to an idea about using nanomaterial-modified microorganisms to produce chemicals, which I’m still researching now.
PAULA MARTIN-GONZALEZ: Make good use of technology
PhD student, University of Cambridge, UK.
Just before the coronavirus lockdown, my PhD adviser and I decided to write a literature review discussing the integration of medical imaging with genomics to improve ovarian cancer management.
As I was researching the review, I noticed a trend in which some papers were consistently being cited by many other papers in the field. It was clear to me that those papers must be important, but as a new member of the field of integrated cancer biology, it was difficult to immediately find and read all of these ‘seminal papers’.
That was when I decided to code a small application to make my literature research more efficient. Using my code, users can enter a query, such as ‘ovarian cancer, computer tomography, radiomics’, and the application searches for all relevant literature archived in databases such as PubMed that feature these key words.
The code then identifies the relevant papers and creates a citation graph of all the references cited in the results of the search. The software highlights papers that have many citation relationships with other papers in the search, and could therefore be called seminal papers.
My code has substantially improved how I organize papers and has informed me of key publications and discoveries in my research field: something that would have taken more time and experience in the field otherwise. After I shared my code on GitHub, I received feedback that it can be daunting for researchers who are not used to coding. Consequently, I am hoping to build a more user-friendly interface in a form of a web page, akin to PubMed or Google Scholar, where users can simply input their queries to generate citation graphs.

Reviewing the Literature: Why do it?
- Personal: To familiarize yourself with a new area of research, to get an overview of a topic, so you don't want to miss something important, etc.
- Required writing for a journal article, thesis or dissertation, grant application, etc.
Literature reviews vary; there are many ways to write a literature review based on discipline, material type, and other factors.

Literature reviews
Writing a literature review.
The following guide has been created for you by the Student Learning Advisory Service . For more detailed guidance and to speak to one of our advisers, please book an appointment or join one of our workshops . Alternatively, have a look at our SkillBuilder skills videos.
Preparing a literature review involves:
- Searching for reliable, accurate and up-to-date material on a topic or subject
- Reading and summarising the key points from this literature
- Synthesising these key ideas, theories and concepts into a summary of what is known
- Discussing and evaluating these ideas, theories and concepts
- Identifying particular areas of debate or controversy
- Preparing the ground for the application of these ideas to new research
Finding and choosing material
Ensure you are clear on what you are looking for. ask yourself:.
- What is the specific question, topic or focus of my assignment?
- What kind of material do I need (e.g. theory, policy, empirical data)?
- What type of literature is available (e.g. journals, books, government documents)?
What kind of literature is particularly authoritative in this academic discipline (e.g. psychology, sociology, pharmacy)?
How much do you need?
This will depend on the length of the dissertation, the nature of the subject, and the level of study (undergraduate, Masters, PhD). As a very rough rule of thumb – you may choose 8-10 significant pieces (books and/or articles) for an 8,000 word dissertation, up to 20 major pieces of work for 12-15,000 words, and so on. Bear in mind that if your dissertation is based mainly around an interaction with existing scholarship you will need a longer literature review than if it is there as a prelude to new empirical research. Use your judgement or ask your supervisor for guidance.
Where to find suitable material
Your literature review should include a balance between substantial academic books, journal articles and other scholarly publications. All these sources should be as up-to-date as possible, with the exception of ‘classic texts’ such as major works written by leading scholars setting out formative ideas and theories central to your subject. There are several ways to locate suitable material:
Module bibliography: for undergraduate dissertations, look first at the bibliography provided with the module documentation. Choose one or two likely looking books or articles and then scan through the bibliographies provided by these authors. Skim read some of this material looking for clues: can you use these leads to identify key theories and authors or track down other appropriate material?
Library catalogue search engine: enter a few key words to capture a range of items, but avoid over-generalisations; if you type in something as broad as ‘social theory’ you are likely to get several thousand results. Be more specific: for example, ‘Heidegger, existentialism’. Ideally, you should narrow the field to obtain just a few dozen results. Skim through these quickly to identity texts which are most likely to contribute to your study.
Library bookshelves: browse the library shelves in the relevant subject area and examine the books that catch your eye. Check the contents and index pages, or skim through the introductions (or abstracts, in the case of journal articles) to see if they contain relevant material, and replace them if not. Don’t be afraid to ask one of the subject librarians for further help. Your supervisor may also be able to point you in the direction of some of the important literature , but remember this is your literature search, not theirs.
Online: for recent journal articles you will almost certainly need to use one of the online search engines. These can be found on the ‘Indexing Services’ button on the Templeman Library website. Kent students based at Medway still need to use the Templeman pages to access online journals, although you can get to these pages through the Drill Hall Library catalogue. Take a look as well at the Subject Guides on both the Templeman and DHL websites.
Check that you have made the right selection by asking:
- Has my search been wide enough to ensure that I have identified all the relevant material, but narrow enough to exclude irrelevant material?
- Is there a good enough sample of literature for the level (PhD, Masters, undergraduate) of my dissertation or thesis?
- Have I considered as many alternative points of view as possible?
- Will the reader find my literature review relevant and useful?
Assessing the literature
Read the material you have chosen carefully, considering the following:
- The key point discussed by the author: is this clearly defined
- What evidence has the author produced to support this central idea?
- How convincing are the reasons given for the author’s point of view?
- Could the evidence be interpreted in other ways?
- What is the author's research method (e.g. qualitative, quantitative, experimental, etc.)?
- What is the author's theoretical framework (e.g. psychological, developmental, feminist)?
- What is the relationship assumed by the author between theory and practice?
- Has the author critically evaluated the other literature in the field?
- Does the author include literature opposing their point of view?
- Is the research data based on a reliable method and accurate information?
- Can you ‘deconstruct’ the argument – identify the gaps or jumps in the logic?
- What are the strengths and limitations of this study?
- What does this book or article contribute to the field or topic?
- What does this book or article contribute to my own topic or thesis?
As you note down the key content of each book or journal article (together with the reference details of each source) record your responses to these questions. You will then be able to summarise each piece of material from two perspectives:
Content: a brief description of the content of the book or article. Remember, an author will often make just one key point; so, what is the point they are making, and how does it relate to your own research project or assignment?
Critical analysis: an assessment of the relative strengths and weaknesses of the evidence used, and the arguments presented. Has anything conveniently been left out or skated over? Is there a counter-argument, and has the author dealt with this adequately? Can the evidence presented be interpreted another way? Does the author demonstrate any obvious bias which could affect their reliability? Overall, based on the above analysis of the author’s work, how do you evaluate its contribution to the scholarly understanding and knowledge surrounding the topic?
Structuring the literature review
In a PhD thesis, the literature review typically comprises one chapter (perhaps 8-10,000 words), for a Masters dissertation it may be around 2-3,000 words, and for an undergraduate dissertation it may be no more than 2,000 words. In each case the word count can vary depending on a range of factors and it is always best, if in doubt, to ask your supervisor.
The overall structure of the section or chapter should be like any other: it should have a beginning, middle and end. You will need to guide the reader through the literature review, outlining the strategy you have adopted for selecting the books or articles, presenting the topic theme for the review, then using most of the word limit to analyse the chosen books or articles thoroughly before pulling everything together briefly in the conclusion.
Some people prefer a less linear approach. Instead of simply working through a list of 8-20 items on your book review list, you might want to try a thematic approach, grouping key ideas, facts, concepts or approaches together and then bouncing the ideas off each other. This is a slightly more creative (and interesting) way of producing the review, but a little more risky as it is harder to establish coherence and logical sequencing.
Whichever approach you adopt, make sure everything flows smoothly – that one idea or book leads neatly to the next. Take your reader effortlessly through a sequence of thought that is clear, accurate, precise and interesting.
Writing up your literature review
As with essays generally, only attempt to write up the literature review when you have completed all the reading and note-taking, and carefully planned its content and structure. Find an appropriate way of introducing the review, then guide the reader through the material clearly and directly, bearing in mind the following:
- Be selective in the number of points you draw out from each piece of literature; remember that one of your objectives is to demonstrate that you can use your judgement to identify what is central and what is secondary.
- Summarise and synthesise – use your own words to sum up what you think is important or controversial about the book or article.
- Never claim more than the evidence will support. Too many dissertations and theses are let down by sweeping generalisations. Be tentative and careful in the way you interpret the evidence.
- Keep your own voice – you are entitled to your own point of view provided it is based on evidence and clear argument.
- At the same time, aim to project an objective and tentative tone by using the 3rd person, (for example, ‘this tends to suggest’, ‘it could be argued’ and so on).
- Even with a literature review you should avoid using too many, or overlong, quotes. Summarise material in your own words as much as possible. Save the quotes for ‘punch-lines’ to drive a particular point home.
- Revise, revise, revise: refine and edit the draft as much as you can. Check for fluency, structure, evidence, criticality and referencing, and don’t forget the basics of good grammar, punctuation and spelling.

- What Is a PhD Literature Review?
- Doing a PhD
A literature review is a critical analysis of published academic literature, mainly peer-reviewed papers and books, on a specific topic. This isn’t just a list of published studies but is a document summarising and critically appraising the main work by researchers in the field, the key findings, limitations and gaps identified in the knowledge.
- The aim of a literature review is to critically assess the literature in your chosen field of research and be able to present an overview of the current knowledge gained from previous work.
- By the conclusion of your literature review, you as a researcher should have identified the gaps in knowledge in your field; i.e. the unanswered research questions which your PhD project will help to answer.
- Quality not quantity is the approach to use when writing a literature review for a PhD but as a general rule of thumb, most are between 6,000 and 12,000 words.
What Is the Purpose of a Literature Review?
First, to be clear on what a PhD literature review is NOT: it is not a ‘paper by paper’ summary of what others have done in your field. All you’re doing here is listing out all the papers and book chapters you’ve found with some text joining things together. This is a common mistake made by PhD students early on in their research project. This is a sign of poor academic writing and if it’s not picked up by your supervisor, it’ll definitely be by your examiners.
The biggest issue your examiners will have here is that you won’t have demonstrated an application of critical thinking when examining existing knowledge from previous research. This is an important part of the research process as a PhD student. It’s needed to show where the gaps in knowledge were, and how then you were able to identify the novelty of each research question and subsequent work.
The five main outcomes from carrying out a good literature review should be:
- An understanding of what has been published in your subject area of research,
- An appreciation of the leading research groups and authors in your field and their key contributions to the research topic,
- Knowledge of the key theories in your field,
- Knowledge of the main research areas within your field of interest,
- A clear understanding of the research gap in knowledge that will help to motivate your PhD research questions .
When assessing the academic papers or books that you’ve come across, you must think about the strengths and weaknesses of them; what was novel about their work and what were the limitations? Are different sources of relevant literature coming to similar conclusions and complementing each other, or are you seeing different outcomes on the same topic by different researchers?
![](http://writinghelp.online/777/templates/cheerup/res/banner1.gif)
When Should I Write My Literature Review?
In the structure of your PhD thesis , your literature review is effectively your first main chapter. It’s at the start of your thesis and should, therefore, be a task you perform at the start of your research. After all, you need to have reviewed the literature to work out how your research can contribute novel findings to your area of research. Sometimes, however, in particular when you apply for a PhD project with a pre-defined research title and research questions, your supervisor may already know where the gaps in knowledge are.
You may be tempted to skip the literature review and dive straight into tackling the set questions (then completing the review at the end before thesis submission) but we strongly advise against this. Whilst your supervisor will be very familiar with the area, you as a doctoral student will not be and so it is essential that you gain this understanding before getting into the research.
How Long Should the Literature Review Be?
As your literature review will be one of your main thesis chapters, it needs to be a substantial body of work. It’s not a good strategy to have a thesis writing process here based on a specific word count, but know that most reviews are typically between 6,000 and 12,000 words. The length will depend on how much relevant material has previously been published in your field.
A point to remember though is that the review needs to be easy to read and avoid being filled with unnecessary information; in your search of selected literature, consider filtering out publications that don’t appear to add anything novel to the discussion – this might be useful in fields with hundreds of papers.
How Do I Write the Literature Review?
Before you start writing your literature review, you need to be clear on the topic you are researching.
1. Evaluating and Selecting the Publications
After completing your literature search and downloading all the papers you find, you may find that you have a lot of papers to read through ! You may find that you have so many papers that it’s unreasonable to read through all of them in their entirety, so you need to find a way to understand what they’re about and decide if they’re important quickly.
A good starting point is to read the abstract of the paper to gauge if it is useful and, as you do so, consider the following questions in your mind:
- What was the overarching aim of the paper?
- What was the methodology used by the authors?
- Was this an experimental study or was this more theoretical in its approach?
- What were the results and what did the authors conclude in their paper?
- How does the data presented in this paper relate to other publications within this field?
- Does it add new knowledge, does it raise more questions or does it confirm what is already known in your field? What is the key concept that the study described?
- What are the strengths and weaknesses of this study, and in particular, what are the limitations?
2. Identifying Themes
To put together the structure of your literature review you need to identify the common themes that emerge from the collective papers and books that you have read. Key things to think about are:
- Are there common methodologies different authors have used or have these changed over time?
- Do the research questions change over time or are the key question’s still unanswered?
- Is there general agreement between different research groups in the main results and outcomes, or do different authors provide differing points of view and different conclusions?
- What are the key papers in your field that have had the biggest impact on the research?
- Have different publications identified similar weaknesses or limitations or gaps in the knowledge that still need to be addressed?
Structuring and Writing Your Literature Review
There are several ways in which you can structure a literature review and this may depend on if, for example, your project is a science or non-science based PhD.
One approach may be to tell a story about how your research area has developed over time. You need to be careful here that you don’t just describe the different papers published in chronological order but that you discuss how different studies have motivated subsequent studies, how the knowledge has developed over time in your field, concluding with what is currently known, and what is currently not understood.
Alternatively, you may find from reading your papers that common themes emerge and it may be easier to develop your review around these, i.e. a thematic review. For example, if you are writing up about bridge design, you may structure the review around the themes of regulation, analysis, and sustainability.
As another approach, you might want to talk about the different research methodologies that have been used. You could then compare and contrast the results and ultimate conclusions that have been drawn from each.
As with all your chapters in your thesis, your literature review will be broken up into three key headings, with the basic structure being the introduction, the main body and conclusion. Within the main body, you will use several subheadings to separate out the topics depending on if you’re structuring it by the time period, the methods used or the common themes that have emerged.
The important thing to think about as you write your main body of text is to summarise the key takeaway messages from each research paper and how they come together to give one or more conclusions. Don’t just stop at summarising the papers though, instead continue on to give your analysis and your opinion on how these previous publications fit into the wider research field and where they have an impact. Emphasise the strengths of the studies you have evaluated also be clear on the limitations of previous work how these may have influenced the results and conclusions of the studies.
In your concluding paragraphs focus your discussion on how your critical evaluation of literature has helped you identify unanswered research questions and how you plan to address these in your PhD project. State the research problem you’re going to address and end with the overarching aim and key objectives of your work .
When writing at a graduate level, you have to take a critical approach when reading existing literature in your field to determine if and how it added value to existing knowledge. You may find that a large number of the papers on your reference list have the right academic context but are essentially saying the same thing. As a graduate student, you’ll need to take a methodological approach to work through this existing research to identify what is relevant literature and what is not.
You then need to go one step further to interpret and articulate the current state of what is known, based on existing theories, and where the research gaps are. It is these gaps in the literature that you will address in your own research project.
- Decide on a research area and an associated research question.
- Decide on the extent of your scope and start looking for literature.
- Review and evaluate the literature.
- Plan an outline for your literature review and start writing it.

Co-witnesses and the effects of discussion on eyewitness memory by Helen M Paterson
Overview of thesis (introduction)
This introductory section is less than two pages long.
The first paragraph:
- states the overall objective of the thesis
- defines the introduced term
- provides broad motivation for interest in the area
- introduces the sections of the thesis that will address the overall objective.
The other paragraphs describe the content and purpose of each section of the thesis.
Literature review
The literature review is made of up of two chapters.
Chapter 1: Literature review of relevant research
The overall goals of this chapter are to firstly establish the significance of the general field of study, and then identify a place where a new contribution could be made.
The bulk of the chapter critically evaluates the methodologies used in this field to identify the appropriate approach for investigating the research questions.
Purpose | Example |
Establish research territory | “Approximately 77,000 individuals are arrested in the United States each year based primarily on eyewitness testimony (ref.). … the pivotal role that eyewitness testimony plays in some trials, whether or not the jury’s faith in this testimony is warranted.” |
Establish significance of research territory | “One study has shown that eyewitness errors are the most common cause of false convictions (ref.). Almost all innocent individuals exonerated by DNA evidence had been convicted primarily as a result of erroneous eyewitness evidence (ref.) , a great deal of research has focussed on the unreliability of eyewitness testimony (refs.).” |
Establish research niche – discusses what has been found then identifies a gap and points out the inconsistency of results | “The current thesis examines the third way that postevent misinformation may be encountered: through other witnesses. , as the majority of the literature on eyewitness testimony has focussed on the effect of questions and media reports containing misleading information.” |
Motivate the next part of literature review | “Yarmey and Morris (1998) suggest that, ‘The capricious results among these investigations are probably due to methodological differences and variability in subject matter’ (p. 1638). co-witness information on eyewitness reports, , in detail, the different methodologies that have been used to investigate this topic.” |
Further justify the need to investigate the impact of social influences on memory | “ , researchers in memory have aimed to keep procedures free from contamination, such as other people’s memories (ref.). , such a narrow focus may not fully explain how people remember (ref.). Because such ‘contamination’ is common to memory, understanding its effects enables greater knowledge of memory itself (ref.). … , instead of intentionally avoiding the social aspects of memory, they should be explored in their own right.” |
Review the chronological development of research in this area (a chronological approach may not always be appropriate) Discuss one key paper at a time and for each paper: | “ the above studies provide valuable information regarding the social aspects of memory, exercised before applying these results to the judicial area. the results obtained from studies using stories and word lists as stimuli can be generalised to forensic contexts.” … “That is, the differences found between individuals and groups could simply be due to the participants giving their reports for a second time …” … “ on collaborative memory is that the memory of groups is compared with that of individuals. … group performance should not be compared with individual performance but rather with ‘nominal groups’ comprised of pooled, non-redundant data from the same number of people tested individually.” |
Overall conclusion or summary that states why a particular methodological approach has been chosen | “… Most research involving the Experimentally Induced Information methodology seeks to identify the influence of misinformation presented by one witness to another, and therefore the assumption is made that discussion between witnesses is a detrimental process. to also investigate the effects of co-witness information using Natural Discussion Groups . , few studies have used this methodology, and those that have, have yielded mixed findings. , future investigation using the Natural Discussion Group methodology would be helpful to better understand the effects of discussion on memory.” |
Chapter 2: Theoretical explanations of memory conformity
|
|
Establish a reason for this chapter and state the purpose | “While the misinformation effect is a well-established phenomenon, ‘what remains in dispute is the nature of a satisfactory theoretical explanation’ (ref.). … Therefore, memory conformity occurs, we must draw from both cognitive research on memory and social research on conformity. In this section, relevant cognitive and social theories are discussed (1) explain the occurrence of memory conformity and (2) describe factors that influence memory conformity.” |
Introduction/overview of the structure of the review | “Four distinct explanations have been offered for the memory conformity effect: (1) … The empirical evidence relevant to each of these explanations is reviewed in this section.” |
Discuss each of the four explanations using the following structure: | “ normative social influence the conformity that occurs in …, memory conformity that may occur when people give individual statements following discussion in the absence of their co-witness. ( )” |
Compare explanations and draw synthesised conclusions | “The suggestion that memory conformity is a result of biased guessing the informational influence explanation because in both instances … , the feature between the two explanations is that …” … “Whilst biased guessing account for the misinformation effect that occurs in some instances (refs.), research suggests that it is not the only reason for the occurrence of the misinformation effect. ( ) … the misinformation effect may be due memory impairment, rather than just biased guessing.” |
“Informational influence, biased guessing, and modification of memory may help to explain why memory conformity occurs when participants are tested individually, . … these alternative explanations which best explains memory conformity in individual recall following co-witness discussion. ( )” | |
Discuss methodological issues in achieving aim | “One way to determine whether memory conformity occurs because of biased guessing is to …” “Experiments described in this thesis (Studies 5-7) include a warning for some participants about possible misinformation whether participants report misinformation because of informational influence or memory change.” |
Introduce another question of interest and review what has been found so far | “ it has been shown that in some circumstances many people tend to conform to the opinions of others, that some people are able to resist conforming in some situations. For example, … This section of the literature review examines factors influencing whether or not a person is likely to conform that are (1) in the situation, and (2) within the individual.” |
Clarify the relevance to the thesis | “Although the experiments described in this thesis do not attempt to manipulate and test the factors that influence conformity, the results obtained and of the findings.” |
Chapter 5, Study 3: Co-Witness Contamination
This chapter has the following structure:
- Introduction
- Discussion.
The introduction introduces the particular study to be reported on, and includes a three-and-a-half page literature review.
The literature review in this chapter:
- links back to the relevant general findings of the earlier literature review chapters
- briefly reviews the broad motivation for this study
- identifies that two previously used methodologies in this field will be compared to resolve questions about the findings of previous studies which had only used a single methodology
- uses previous literature to generate specific hypotheses to test
- reviews additional literature to provide a justification for a second objective to be investigated in the study reported on in this chapter.

What Is A Literature Review?
A plain-language explainer (with examples).
By: Derek Jansen (MBA) & Kerryn Warren (PhD) | June 2020 (Updated May 2023)
If you’re faced with writing a dissertation or thesis, chances are you’ve encountered the term “literature review” . If you’re on this page, you’re probably not 100% what the literature review is all about. The good news is that you’ve come to the right place.
Literature Review 101
- What (exactly) is a literature review
- What’s the purpose of the literature review chapter
- How to find high-quality resources
- How to structure your literature review chapter
- Example of an actual literature review
What is a literature review?
The word “literature review” can refer to two related things that are part of the broader literature review process. The first is the task of reviewing the literature – i.e. sourcing and reading through the existing research relating to your research topic. The second is the actual chapter that you write up in your dissertation, thesis or research project. Let’s look at each of them:
Reviewing the literature
The first step of any literature review is to hunt down and read through the existing research that’s relevant to your research topic. To do this, you’ll use a combination of tools (we’ll discuss some of these later) to find journal articles, books, ebooks, research reports, dissertations, theses and any other credible sources of information that relate to your topic. You’ll then summarise and catalogue these for easy reference when you write up your literature review chapter.
The literature review chapter
The second step of the literature review is to write the actual literature review chapter (this is usually the second chapter in a typical dissertation or thesis structure ). At the simplest level, the literature review chapter is an overview of the key literature that’s relevant to your research topic. This chapter should provide a smooth-flowing discussion of what research has already been done, what is known, what is unknown and what is contested in relation to your research topic. So, you can think of it as an integrated review of the state of knowledge around your research topic.
![what-is-lit-review Starting point for the literature review](https://gradcoach.com/wp-content/uploads/what-is-lit-review.png)
What’s the purpose of a literature review?
The literature review chapter has a few important functions within your dissertation, thesis or research project. Let’s take a look at these:
Purpose #1 – Demonstrate your topic knowledge
The first function of the literature review chapter is, quite simply, to show the reader (or marker) that you know what you’re talking about . In other words, a good literature review chapter demonstrates that you’ve read the relevant existing research and understand what’s going on – who’s said what, what’s agreed upon, disagreed upon and so on. This needs to be more than just a summary of who said what – it needs to integrate the existing research to show how it all fits together and what’s missing (which leads us to purpose #2, next).
Purpose #2 – Reveal the research gap that you’ll fill
The second function of the literature review chapter is to show what’s currently missing from the existing research, to lay the foundation for your own research topic. In other words, your literature review chapter needs to show that there are currently “missing pieces” in terms of the bigger puzzle, and that your study will fill one of those research gaps . By doing this, you are showing that your research topic is original and will help contribute to the body of knowledge. In other words, the literature review helps justify your research topic.
Purpose #3 – Lay the foundation for your conceptual framework
The third function of the literature review is to form the basis for a conceptual framework . Not every research topic will necessarily have a conceptual framework, but if your topic does require one, it needs to be rooted in your literature review.
For example, let’s say your research aims to identify the drivers of a certain outcome – the factors which contribute to burnout in office workers. In this case, you’d likely develop a conceptual framework which details the potential factors (e.g. long hours, excessive stress, etc), as well as the outcome (burnout). Those factors would need to emerge from the literature review chapter – they can’t just come from your gut!
So, in this case, the literature review chapter would uncover each of the potential factors (based on previous studies about burnout), which would then be modelled into a framework.
Purpose #4 – To inform your methodology
The fourth function of the literature review is to inform the choice of methodology for your own research. As we’ve discussed on the Grad Coach blog , your choice of methodology will be heavily influenced by your research aims, objectives and questions . Given that you’ll be reviewing studies covering a topic close to yours, it makes sense that you could learn a lot from their (well-considered) methodologies.
So, when you’re reviewing the literature, you’ll need to pay close attention to the research design , methodology and methods used in similar studies, and use these to inform your methodology. Quite often, you’ll be able to “borrow” from previous studies . This is especially true for quantitative studies , as you can use previously tried and tested measures and scales.

How do I find articles for my literature review?
Finding quality journal articles is essential to crafting a rock-solid literature review. As you probably already know, not all research is created equally, and so you need to make sure that your literature review is built on credible research .
We could write an entire post on how to find quality literature (actually, we have ), but a good starting point is Google Scholar . Google Scholar is essentially the academic equivalent of Google, using Google’s powerful search capabilities to find relevant journal articles and reports. It certainly doesn’t cover every possible resource, but it’s a very useful way to get started on your literature review journey, as it will very quickly give you a good indication of what the most popular pieces of research are in your field.
One downside of Google Scholar is that it’s merely a search engine – that is, it lists the articles, but oftentimes it doesn’t host the articles . So you’ll often hit a paywall when clicking through to journal websites.
Thankfully, your university should provide you with access to their library, so you can find the article titles using Google Scholar and then search for them by name in your university’s online library. Your university may also provide you with access to ResearchGate , which is another great source for existing research.
Remember, the correct search keywords will be super important to get the right information from the start. So, pay close attention to the keywords used in the journal articles you read and use those keywords to search for more articles. If you can’t find a spoon in the kitchen, you haven’t looked in the right drawer.
Need a helping hand?
How should I structure my literature review?
Unfortunately, there’s no generic universal answer for this one. The structure of your literature review will depend largely on your topic area and your research aims and objectives.
You could potentially structure your literature review chapter according to theme, group, variables , chronologically or per concepts in your field of research. We explain the main approaches to structuring your literature review here . You can also download a copy of our free literature review template to help you establish an initial structure.
In general, it’s also a good idea to start wide (i.e. the big-picture-level) and then narrow down, ending your literature review close to your research questions . However, there’s no universal one “right way” to structure your literature review. The most important thing is not to discuss your sources one after the other like a list – as we touched on earlier, your literature review needs to synthesise the research , not summarise it .
Ultimately, you need to craft your literature review so that it conveys the most important information effectively – it needs to tell a logical story in a digestible way. It’s no use starting off with highly technical terms and then only explaining what these terms mean later. Always assume your reader is not a subject matter expert and hold their hand through a journe y of the literature while keeping the functions of the literature review chapter (which we discussed earlier) front of mind.

Wrestling an elephant into a cupboard: how to write a PhD literature review in nine easy steps
Feb 10, 2019
![how to write a literature review for a phd dissertation how to write a literature review](https://www.thephdproofreaders.com/wp-content/uploads/2019/03/how-to-write-a-literature-review.jpg)
When I was writing my PhD I hated the literature review. I was scared of it. One day, my supervisor took me to one side and told me that I had no choice: ‘It was going to have to be done before you start fieldwork’. I was terrified.
Sound familiar? According to Google, 5,000 people a month search for advice on how to conduct a literature review. And we know from the one-on-one PhD coaching we offer and from the theses we proofread that many students struggle with this part of their thesis.
If you’re feeling lost, keep reading. In this guide, I’ll walk you through the nine steps involved in conducting and writing a PhD literature review.
You’ll realise what I eventually found out: C onducting a literature review is easy. Okay, perhaps that’s a bit much. Let me rephrase: Conducting a PhD literature review isn’t as hard as you think.
What a PhD literature review isn’t
Let us make one thing very clear. A PhD literature review isn’t just a summary of existing literature. That’s an annotated bibliography and that isn’t what a PhD literature review is about. This is the mistake I see most frequently in the PhDs I proofread.
Not only will your examiners send this back for corrections, but it may mean the whole PhD thesis is problematic because it isn’t grounded in a critical review of the literature.
What a PhD literature review is
A PhD literature review is a critical assessment of the literature in your field and related to your specific research topic. When discussing each relevant piece of literature, the review must highlight where the gaps are and what the strengths and weaknesses are of particular studies, papers, books, etc. Also, different pieces of literature are compared and contrasted with one another so that themes and relationships are highlighted.
The job of a literature review is to show five things (if you’re using our PhD Writing Template , you may recognise these):
1. What has been written on your topic 2. Who the key authors are and what the key works are 3. The main theories and hypotheses 4. The main themes that exist in the literature 5. Gaps and weaknesses that your study will then help fill
Who cares what other people have written and said, or what they haven’t said? Well, you should and your examiners definitely will. For your own study to make sense, it has to be situated in the literature. That means you must relate it to what others are talking about.
If you wanted to build a new mobile phone, you would have to research how other mobile phones are built, find out where they can be improved and then design one that makes those improvements.
The literature review is the same.
But where do I start? Here, we list nine steps. Follow each and you’ll be on your way to literature review greatness.
We’ve made the infographic below to help you on your way. Click the image to download it.
![title= how to write a literature review for a phd dissertation](https://www.thephdproofreaders.com/wp-content/uploads//2019/02/Literature-Review_Infographic_V01-3.jpg)
Step One: Pick a Broad Topic
You will be reviewing literature on a particular topic, so knowing what your topic is beforehand means you can narrow down your search. At this stage your topic is broad. You won’t be able to know the specifics until you do the review itself.
For my PhD, which looked at the contributions that local government made to climate change policy, my literature review started with a broad topic of ‘climate change policy’. I didn’t focus in on local government until I had read the literature on climate change policy and realized there was a gap.
So, having a clearly defined purpose is really important. Otherwise you are searching blind. If you refer to your PhD Writing Template, take a look at the box titled ‘Aims & Objectives’ – you’ll need to make sure you have established your aims, scope and research questions.
Step Two: Find the Way In
If you search for your broad topic in Google Scholar, you’ll be presented with millions of results. With my own PhD, a search for ‘climate change policy’ bought up over 3 million results.
Obviously it’s unfeasible to read through all these.
So where do you start? Easy: choose the biggest names in your field.
There are three ways to find these:
1. Textbooks 2. Review articles 3. Most-cited articles
Read through these seminal texts and you’ll begin to get an idea of the broad topic.
Step Three: Who’s Saying What & When
Your job at this stage is to find out the key debates in the field.
- Who is making the most significant contribution?
- What are they saying?
- How are they saying it?
- What aren’t they saying?
Step Four: Notes, Notes, Notes.
Whenever you read anything you should be taking notes. Detailed notes. These need to cover the following points:
- What is the author saying?
- How is it relevant to your research?
- What are the gaps/weaknesses?
- What are the key references that you should read?
The more of these kind of standardised notes you have, the easier it will be when you write your literature review.
Step Five: Narrow Down the Field
As you read the key texts, you will begin to see what the key debates are in your field. There might be a number of ’schools’, for example. When you become aware of them, start to focus your literature review around them.
Step Six: Filter Through Your Growing List of References
Don’t just read everything. You need to find a way to filter through the articles or books that are relevant. For example, scan the abstracts, introduction, keywords, titles and references.
Filter the sources you come across into three separate categories:
- Probably won’t read
Step Seven: Use Snowball Sampling
As you read through these articles, look at their reference list. Collect articles that you think will be relevant and use them in your literature review. This is known as snowball sampling.
Step Eight: Think About the Questions that Haven’t Been Asked
You must be reading critically, which means asking what the weaknesses are and where particular articles or book could be improved.
In order to tease out your own specific research topic, you need to think of the questions that haven’t been asked.

Learn what goes where (and why), and how it all fit together with this free, interactive guide to the PhD literature review and theory framework.
Step Nine: Writing Up Your Literature Review
The review will broadly follow the key debates you have spotted in step five above. As you write, focus on putting in more detail about particular sources (i.e. flesh out steps six and seven). The focus when writing is to elaborate upon the key patterns and themes that have emerged.
However, you need to include your own synthesis of the material. I said earlier that you shouldn’t just summarize the literature. Instead you should write critically. You should clearly and precisely present your argument. The argument will focus around the questions that haven’t been asked – step nine above – and will ground the literature review. We’ve written a guide to being critical in your literature review . You should read it if you’re unsure what’s required.
So, write early and write that first draft quickly. The earlier you start writing your literature review the better. You must accept that your first draft is going to be just that: a draft. When you write the first draft, focus on the broad structure first. This means focus on the broad themes you want to discuss in the review.
Something you need to consider is how to structure the chapter. The simple answer is that you can either structure it chronologically or thematically.
The long answer is that chronological literature reviews are restrictive and over-simplify the field. They are useful for very early drafts of the review and can help you to arrange the literature and trace threads and connections within it. However, your supervisors and examiners are looking for thematic reviews (unless they have told you otherwise), where you discuss the literature with reference to the themes that have emerged.
Equally important is knowing when to stop reviewing the literature.
The sooner you go out and do your fieldwork, the better. The literature review is a cruel mistress; you’ll struggle to fully nail down its various components and fully understand how everything you have read is related. But don’t despair; aspects of the literature review will become clearer when you enter the field and start to collect data.
Don’t fall into the trap of spending too long in the library and too little time doing fieldwork.
It’s natural to be scared of the literature review. To conduct one, you have to read, process and synthesise hundreds of thousands of words. But it’s not impossible. Keep this guide to hand and refer to it when you feel yourself getting lost. Share it with your colleagues so they too can conquer their fear of the literature review.

Are you tired of hearing the phrase 'literature review' every five minutes at university and having no idea what it means, let alone where to start? Not to worry - we've got you covered with this step-by-step guide to creating a great dissertation literature review.
What is a literature review?
In short, a dissertation literature review provides a critical assessment of the sources (literature) you have gathered and read surrounding your subject area, and then identifies a “gap” in that literature that your research will attempt to address.
There are a lot of misunderstandings about what exactly a dissertation literature review entails, as it can vary. Whilst in some cases a dissertation literature review can be a simple summary of important sources, most often it requires you to critically engage with the text to convey your positive or negative opinions of it. What is your interpretation of a particular source? Does this interpretation differ considerably from other viewpoints in the literature? This is the sort of critical engagement expected from you in a literature review.
Whereas a summary will most likely provide a simple recap of the general arguments of the source(s), the expectations concerning a literature review extend beyond this. A literature review may provide a new perspective on a classic research paper or it may combine both new and old interpretations (this is the “gap” – more on this later). A literature review may also provide a thorough and critical outline of the intellectual developments in a field with a focus on major, and often polemical, debates. In other scenarios, a literature review may also provide an assessment of a source and inform a reader about its validity, pertinence and relevance to the research subject.
"In a literature review, you're aiming to summarise and provide a critical analysis of the research arguments you have found in your readings, without making new contributions to the literature. Hence the term: “literature review ”."
There tends to be confusion between literature reviews and academic papers in general, but they are not one and the same. Generally, academic papers aim to provide new research material about a particular subject, and a literature review features as part of this objective. In a research paper, the literature review forms the basis of the research – it helps to highlight any research gaps as support for a new argument or insights you intend to provide. In a literature review, you're aiming to summarise and provide a critical analysis of the research arguments you have found in your readings, without making new contributions to the literature. Hence the term: “literature review ”.
Is a literature review really necessary?
Now that we know what a literature review is, the next step is to understand the point of writing one in the first place. Like it or not, a literature review is an essential part of any academic piece of writing, as it demonstrates to your tutor or reader that you have a nuanced understanding of the sources concerning your research area or question.
Although it may seem arbitrary, the literature review helps to persuade the person reading and marking your assignment that what you have written about is relevant and your arguments are justified and worthwhile. So, in short, a literature review is essential, and you need to put the necessary time into getting it right.
How do you write a dissertation literature review?
As the next section of this blog is quite lengthy, we've broken it down into several key steps which should make it easier to follow when writing your own dissertation literature review. You start by identifying your sources, then you read and re-read them. Next, you think about any gaps in the research or literature you have used, and finally, you write your review using all the preparation and information gathered in the steps prior.
Identify sources
To write a good dissertation literature review, you need to have a fair idea of what sources you would like to review. If you haven’t been given a formal reference list by your tutor, refer back to the techniques we recommended earlier.
Make sure that your sources are balanced; include enough books and academic journals and any useful published work from reputable scholars. To help you choose your sources appropriately, you might want to think about the parameters and objectives of your research. What are you hoping to find out? In your literature review , what theoretical issues or perspectives do you aim to tackle? How about your methodology? Will you focus on mainly qualitative or quantitative studies, or a mixture of both? These general questions should help guide you in selecting your sources and again, remember that the abstract of a source is a very useful tool. Having a quick scan of the abstract and its ‘keywords’ will often give you an indication of the whether the source will be useful for your research or not.
As you’re identifying your sources, ensure you a keep a list as it’s very easy to lose focus given the wide scope of the Internet. Reference tools such as Mendeley allow you to store your sources online and via a desktop app, and are a great way to keep your bibliography organised. The citation tools attached to these programmes will also allow you to simply export citations in a format of your choice when required later. They will save you countless hours trying to figure out how to use Harvard or APA referencing correctly.
Read your sources
Now that you have organised your sources efficiently, it’s time to read through them. As unnatural as it may feel, it’s most effective to read in a few stages, as detailed below:
First, go through all the texts to get a sense of their general content and arguments. This will also help you judge which sources you mainly want to focus on in your review. During the second stage of your reading, you can then take a more critical, in-depth look at your sources. Make a lot of notes, be critical, ask questions. What is your academic opinion on the text? Do you have any comments on the methodological approach, the theoretical argument or the general hypothesis? Note these down. It will ensure that your literature review is not merely a summary of your readings, and will encourage a clear line of argument so that your work is logical and coherent.
Consider gaps in the research
When writing a dissertation literature review, an essential thing to consider is identifying the research gap. Identifying the gap is particularly important if your review forms part of a research proposal, as it will highlight the pertinence of your research – assuming that your research has been designed to fill this gap. In other instances, identifying the gap is an indication of good critical analysis and can score you extra points.
To identify the “gap” it is important that we know what this “gap” is. A research gap is essentially the existence of a research question, perspective or problem that has not been answered in the existing literature on any field of study. Identifying the research gap is important for highlighting the originality of your research; it proves you’re not simply recounting or regurgitating existing research. It also shows that you are very much aware of the status of the literature in your chosen field of study, which in turn, demonstrates the amount of research and effort you have put into your review.
Many students, especially at post-graduate level, find it extremely difficult to identify research gaps in their subject area. For post-graduate research papers, identifying research gaps and formulating research questions that can address these gaps form the very essence of a research paper. Identifying research gaps does not have to be a difficult endeavour and there are several ways to overcome this difficulty:
Start by reading A simple approach will be to read important parts of key articles in your research area. First, note that you’ll have to sift through many articles to identify the ones that are most suitable for your research. A quick search using keywords on Google Scholar will often give you a quick overview of the available literature. Other useful sources include databases such as JSTOR or Wiley Online Library . You can then snowball additional articles by clicking on ‘related articles’ or checking out which other papers have cited your source.
Abstracts and recommendations Whichever avenue you choose, reading the abstract is often a good starting point to get a sense of what the articles entails. You should also do a quick examination of the introductory and concluding paragraphs of the paper as these sections always provide some information on the aims and outcomes of the research, as well as ‘recommendations for future studies.’ These recommendations typically provide some insight on the research gaps in the literature. Another route would be to simply read as much as you can on your research subject while considering which research areas still need addressing in the literature – this is usually an indication of research gaps.
![how to write a literature review for a phd dissertation how to write a literature review for a phd dissertation](https://d15g6vdo5z6qmo.cloudfront.net/2021/11/Webp.net-compress-image-21.jpg)
Write your review
Now you’re well prepared to start putting fingers to keyboard. Consider the following pointers:
1. Use sample literature reviews Have a look at sample dissertation literature reviews in your subject area and read them thoroughly to familiarise yourself with existing key debates and themes. This can be a good starting point for framing and structuring your own review. If you are not familiar with academic writing, going through samples will help you to get a sense of what is expected in this regard. Pay attention to the academic language and formal style used. Also, remember that the bibliography or reference section of your selected texts will help you to snowball further references if you need any.
2. Keep it simple Keep your topic as narrowed down as possible. Remember that there are hundreds – or in some instances, thousands – of sources or perspectives concerning any subject area or topic. Researchers investigate research problems in many divergent ways and the literature available on any given subject is extremely broad. In your literature review, you won’t be expected to address every argument or perspective concerning your topic – this might actually undermine your ability to write a coherent and focused piece. You’ll make your work easier if you limit the scope of your work. In your review, ensure that you clearly state what the focus of your work will be.
3. Make sure your sources are as current as possible If you are reviewing scientific work, it’s essential your sources are as current as possible given the advancements in the field over the years. In the medical field particularly, research is constantly evolving and a source that’s only three years old may be even out-dated. In the social sciences this rule may not apply, as many theoretical works are classics and you will be expected to be familiar with these perspectives. You might have to the review the work of Marx, or Hobbes, or any other classic scholar. You still need to balance theory with current approaches, as you will need to demonstrate the ways in which perspectives in the literature have changed over the years, or you may even want to demonstrate how scholars have used classic theories to inform their work.
4. Consider the organisation of your work In a dissertation literature review, organising your work goes beyond having an introduction, body and conclusion. You’ll be reviewing a number of texts, so you’ll also have to think clearly about how to organise themes, topics and your argument in general. Below is a detailed guide on how to do this:
Like any other academic paper, a dissertation literature review will comprise a basic introduction, body, and conclusion.
The introduction of a literature review should be clear, short and focused. It should outline the focus of the review – in other words, it should clearly state the main topics to be covered. A good literature review will also state the arguments to be made, as well as underlying rationale that underpins these arguments.
The body of your literature review will include an in-depth discussion of the academic sources you have chosen to review. You may choose to organise your sources according to themes, methodology or even based on a chronological order. In the body of your review, ensure that your arguments are presented clearly and that you link these arguments with the literature. Is there a scholar that agrees with your view? Say so, in a way that the reader will understand easily. This demonstrates that you are very familiar with the academic research in your field. Remember to also make note of any views that do not agree with your position; excluding these arguments will reduce the methodological robustness of your piece. You can use direct quotations in your literature review, however do so sparingly so you don’t appear lazy. Most tutors will not approach it kindly; the purpose of a literature review is to demonstrate your ability to critically engage with a piece of text, and littering your review with direct quotes isn’t a good indication of this. Instead, try to paraphrase quotations and only use direct quotes if it really helps to illustrate your argument.
In the summary of your dissertation literature review, it’s important to give a summary of the conclusions you’ve drawn from your readings. If your literature review forms part of a broader research proposal, reiterate the gaps in the literature here, and clearly state how your proposed research will fill these gaps. Make recommendations for future research in this section too, which demonstrates your analytical skills and will score you some extra points.
You now have the basic structure of your research in place, however it’s worth dedicating some time to what the body of your work should entail. The body is the main core of your work, so it’s important to consider how you will frame and organise it. You have options here – you can choose to organise the content of your work based on a chronological method, based on themes, trends or methodology, or based on arguments.
To structure the body of work chronologically, you will have to organise your sources based on when they were published. A limitation of this approach is that it inhibits continuity in your arguments and in some instances, can undermine the coherence of your work. Use with caution.
A more coherent way of organising your work is to group your sources based on the arguments they make in a ‘for versus against’ manner. This enables you to present your work in a more dynamic way and what’s more, makes the key debates in the literature more obvious. Say you were trying to convey the debates on European migration policy, you might want to start by writing something along these lines:
"While scholars such as X argue that migration policies must be made more stringent to counteract the increased flow of Syrian refugees to Europe, other scholars such as Y offer a divergent perspective. They specifically espouse a perspective based on a human rights approach…"
This approach also leaves room for you to insert your voice into the literature. Consider this statement:
"While X argues for the enactment of more stringent migration policies, this paper argues along the lines of Y that migration policies should be based on human rights considerations."
Using this technique also allows you to introduce additional literature that supports your position.
Another way of organising your content is according to theme; or sub-themes, if your review focuses on one overarching topic. This method of organisation still allows you to present an overview of any polemical debates within these sub-themes. A thematic review can easily shift between chronological periods within each sub-section too.
Structuring work using a methodological approach is quite a common approach, however it’s often used in tandem with other ways of organising sources. This method is particularly evident in introductory sections whereby researchers may simply want to state that a particular subject has been mostly studied from a qualitative or quantitative perspective (they will often then cite a number of scholars or studies to support this claim). In scientific reviews however, a methodological approach may form the basis of the discussions in the body. If this is the case for you, focus on the methods used by various researchers. How did they go about answering a particular research question? Were there any limitations to this method? If so, what method(s) would have been better?
You’ll soon realise that organising the body of your literature review is an iterative process and you’ll more often than not use all of these approaches in your write-up. The body of your research may also include additional sections that do not necessarily form a part of its organisational structure. For instance, you might want to include a ‘context section’ that provides some insight on any background detail required for understanding the focus of the literature review. It may also focus on historical considerations. You could include a short methodology section that details the approach you used in selecting and analysing your sources.
5. Write the paragraphs of the body Once you have settled on the approach to writing your body, you must now write each of its paragraphs in a way that is in keeping with academic conventions. Consider this paragraph from a literature review about stakeholder participation for environmental management, to clarify the discussion that follows:
As the example above suggests, a dissertation literature review must be written using a formal and academic style . Also, note how sources have been grouped according to both arguments and themes. Remember we noted that the process of grouping sources in the body of your literature review is never a linear one? You will often use a combination of the approaches that we have discussed. Ensure that your writing is concise, coherent and devoid of any personal or strong language. Avoid any phrases like, “I hate X’s work”; a more academic way of stating your disagreement would be to simply state: “I would argue against X’s position that…”, or “X’s argument is inconsistent with the evidence because...”, or “X’s arguments are based on false assumptions because...”.
In the sample paragraph above, notice the use of words like “argue” – this is a good academic alternative to more commonplace words such as “says”. Other good alternatives include “states”, “asserts”, “proposes” or “claims”. More academic options include “opine”, “posit”, “postulate”, or “promulgate”, however some tutors and readers find these words to be too ‘heavy’ and archaic, so ensure that you are familiar with the writing standards in your institution.
If your writing is tailored to a peer-reviewed journal, it’s worth having a look at articles within that journal to get a sense of the writing style. Most tutors will provide a guideline on writing styles, and it’s important you adhere to this brief. You will often be required to also use the third person when writing a literature review, thus phrases such as “this paper argues” or “this paper is of the view that…” are appropriate.
There are exceptions at post-graduate level or generally – like when you have conducted your own primary research or published your work widely – which give you the academic authority to boldly make claims. In cases like these, the use of first person is suitable and you may use phrases such as “I argue” or “I propose”.
Remember also to generally use present tense when referring to opinions and theories (although in the context of specific research experiments, the use of the past tense is better).
Beyond the use of the academic terms suggested above, ‘linking’ words are also particularly important when writing a literature review, since you’ll be grouping a lot of writers together with either similar or divergent opinions. Useful linking words and phrases include: similarly, there are parallels, in convergence with…
When there is disagreement, you may want to use any of the following: However, conversely, on the other hand, diverges from, antithetical to, differential from…
6. Write the conclusion The conclusion of a dissertation literature review should always include a summary of the implications of the literature, which you should then link to your argument or general research question.

Some final notes
The overall structure of your literature review will be largely based on your research area and the academic conventions that are in line with it. Nevertheless, there are some essential steps that apply across all disciplines and that you should ensure you follow:
Do not simply describe the opinions of writers Analyse, analyse, analyse, and ensure that your analysis is critical (what have the writers missed; where does your opinion sit with theirs, etc.).
Structure the body of your argument using various techniques Your structure should be organised based on thematic areas, key debates or controversial issues, and according to methodological approaches. Keep your review dynamic, but coherent. Remember to identify literature gaps and link this to your own research.
Use ample evidence This is extremely important and forms the very essence of a dissertation literature review. You must refer to various sources when making a point; see the sample paragraph above for an example of this. Your arguments and interpretation of a research topic must be backed by evidence. Do not make baseless claims, as a literature review is an academic piece of writing and not an opinion piece.
Be very selective Not every piece of research has to be reviewed. If you are determined to show that you aware of the available literature out there, try writing techniques such as: There is robust literature available concerning the migration patterns of Syrian refugees. Notable works include: X(2015), y (2013), Z (2014). Once you have acknowledged these works, you do not have to review them in detail. Be selective about the sources that you will discuss in detail in your review.
Do not rely too much on direct quotes Only use them to emphasise a point. Similarly, don’t rely too heavily on the work of a single author. Instead, highlight the importance of that author in your research and move on. If you need to keep going back to the work of that author, then you need to link those discussions with your work. Do not simply provide a summary of the author’s work. In what ways does your work agree or disagree with his/hers? Be critical.
Make your voice heard Yes, the whole point of the literature review is to provide a critical analysis and summary of the viewpoints out there, but a critical analysis does include the fact that you need to make your opinion known in the context of the literature. Note how skilfully, in the earlier sample paragraph by Reed (2008), he weaves his opinions with references. Read back over the sample and try to perfect this skill.
Ensure that you reference your work correctly And make sure you use the appropriate referencing style. For more help on this, click here .

How to enjoy writing your PhD thesis
- by James Hayton, PhD
- July 25th, 2024
How to stop worrying and learn to love your PhD
Unlike a lot of students I actually enjoyed writing my PhD thesis, so in this post I share some of the things I did a little differently…
Don’t worry about what the examiners will think
I decided before I started writing not to invest energy into worrying about what the examiners thought of my work, or whether I would pass or fail the defence. This isn’t to say I wouldn’t have been affected had I failed, but worrying about it in advance wouldn’t have helped in any way.
Focus on your strengths and what you find interesting
I also decided to focus on the areas where I was strongest and what I found most interesting.
I’d spent a lot of time, especially early in my PhD, worrying about the gaps in my knowledge, but focusing on what I was good at made it a lot easier to write, easier to defend, and I think also more interesting for the examiners.
Put care into your writing
While I tried not to worry about what the examiners would think, I still put care into the work. I didn’t “just get words down on the page” or try to write a “shitty first draft” as so many people advise, I took my time to think about what I wanted to say and how I wanted to say it.
Whenever I mention this people often raise the issue of perfectionism, but what people call perfectionism is often just indecision stemming from a lack of confidence, and writing as fast as you can doesn’t really solve that problem.
If you want to write well, you need to put some care into it, and if you want to make an intelligent academic argument, you need to give it some thought. Now if you over-think and doubt everything it’s a problem, and this is why you also need to make confident decisions and move forwards.
Set a daily target
To help me do this, I set myself the target of writing a minimum of 500 words per day. For me, that was a relatively easy target I could beat almost every day. Sometimes I could write 500 words in about an hour, other times it would take all day, depending on what I was writing about. Some things are more difficult to write about than others, so they take a bit longer: So this target allowed for a bit of variation in pace, it allowed me to slow down and think when I needed to, while also making sure I made decisions and moved forwards.
For me, 500 words per day was an achievable target, but I was writing in my native language and was able to work on it full time. So set a target that you can beat. That might be a minimum of, say, 150 words, but it adds up if you do it consistently.
Having an objective measure of success meant that if I smashed my target I felt good, and if it took all day to reach 500 words I could feel good about overcoming the difficulty… That meant that I finished pretty much every day feeling good about my progress.
Celebrate small wins
To reinforce that good feeling, I also created a grid to stick on the wall next to the computer. Each block represented 500 words, each row of 4 blocks represented 2000 words, 5 rows represented 10,000 words, and the whole sheet represented 20,000.
![how to write a literature review for a phd dissertation Word count grid](https://phd.academy/wp-content/uploads/2024/07/10000-2-300x300.png)
As I increased the word count, colouring in the blocks helped visualise and reinforce my progress. It was a small thing, but it just felt really good to do.
Stop with something in reserve
Part of the reason for setting these word-count targets was to help maintain consistency from one day to the next. While there was some variability, I was at least getting the minimum done every day and my average per day was higher.
Another way I tried to ensure consistency was by stopping each day while I still had energy in reserve. Some students, when they feel they’re in the flow, keep going late into the night for fear that they won’t be able to recapture the energy the next day. But that approach of working to exhaustion guarantees that they won’t have energy the next day.
By stopping with something in reserve, I could switch off and let my brain relax and process, and as a result I was able to start the next day well rested.
Stay with problems until you find a solution
Another slightly unusual aspect of my approach was that I started with the introduction and worked in sequence through the document, instead of starting somewhere in the middle, or working on several sections at the same time and jumping between them. The metaphor I use for this is that it’s like digging a tunnel through a mountain. You can’t start in the middle, you have to start at the beginning and as you progress you can only dig at the rock face in front of you.
This meant that I never had to decide what to work on- I had a clear point of focus which in some ways made things much simpler, but it also meant that whenever I hit a problem—something I wasn’t sure about or something that was difficult to explain—I had to face the problem and find a solution.
Most people will just switch to writing about something else, and while that helps you increase the word count, at least in the short term, it removes any possibility that you solve the problem. Eventually, you’ll run out of easy things to write about and all you’re left with is the difficult problems you ran away from, which you then have to face all at the same time, when you’re probably under the most time pressure.
Worse, instead of learning how to solve problems in your writing, you will have trained the habit of avoiding problems, and habits are very hard to break when you’re under great stress. But if you face problems as they arise, slow down and deal with them, that’s when you develop your skill and confidence as a writer, and that’s when you can start to enjoy writing your PhD thesis.
Finish sections before you move on
Related to the last point, another unusual thing I did was to try to finish each section, to a submittable standard, before moving on to the next. This meant reading through it, editing it, and wherever possible taking care of any references and formatting and any other details, rather than leaving them for later. I often speak to students who have written a lot, maybe 100,000 words or more , but nothing is actually finished, not one section actually looks submittable because it’s not properly formatted, there are loads of missing references and incomplete sections and notes to self.
The more you write this way, the more mess you’ll create, so it’s not surprising if you feel like you’re working and working but not getting any closer to the finish line. And again, you’re training the habit of not finishing what you’re working on, and you’ll have to try to tidy up everything at the same time at the end. Guaranteed stress.
But if you tidy up as you go, finishing the sections you work on to a submittable standard, or as close to submittable as possible, then you’ll probably have a lot more confidence that you can finish the whole thesis, and you’ll be able to look back at the sections you’ve done with pride.
Your thoughts?
I know that some of you will be thinking, “yeah but I can’t write this way because…” If so, leave a comment below and I might be able to help. I can’t guarantee that you’ll enjoy writing, but if we can reduce the suffering it’s definitely worth it.
Also, if you enjoy writing, how do you do it? Is there anything you do that’s a little different?

How to Write a PhD Research Proposal
![PhD research proposal PhD research proposal](https://pp-blog.paperpal.com/wp-content/uploads/2024/07/47731-1-1170x780.jpg)
Starting on PhD research is a big step in a researcher’s academic journey, and submitting a research proposal is a significant part of it. Indeed, many PhD scholars seek guidance on how to write a PhD research proposal , which is the foundational document that outlines the scope, objectives, and methodology of their prospective doctoral study. This article takes a look at the essential elements of a PhD research proposal and discuss practical steps to help develop an effective and strong document.
What is a PhD Research Proposal ?
Think of a PhD research proposal as a blueprint for your research. It lays out the main questions you want to seek answers to in your study, and presents an overview of the field you are planning to dive into. The PhD research proposal is not just about summarizing what is already available in the public domain. It is a critical document that demonstrates the feasibility, significance, and originality of the proposed research, and therefore, plays a crucial role in influencing admission decisions and securing funding opportunities. It also explains how your research is different and new and underscores the unique angles, perspectives and originality of your area of study.[ 1]
Why is a PhD Research Proposal Needed?
Even though your research proposal focuses on what you plan to do in the future, supervisors and funders also want to see what you have already achieved academically. Their interest lies in how well you understand the existing research, including recent studies and discussions in your academic field.
Therefore, it is essential to showcase your awareness about gaps in current knowledge and how your research will develop new knowledge and perspectives. Presenting a clear and detailed picture of this background is critical.[ 2]
How to Structure Your PhD Research Proposal ?
Research proposals can vary based on the institution you wish to send the proposal to or your subject of study, but there is a broad structure that needs to be followed.[ 3][4][5] A good PhD research proposal structure should highlight what makes your idea unique, feasible, and significant.
Follow these proven tips to structure a PhD research proposal and make it stand out:
- Provisional Title: The title should not only describe the subject matter but also hint at your approach or main question.
- Key Question: The key question is crucial for defining the scope and purpose of the research, making sure everything stays clear and organized.
- Topic Description: This section serves to introduce readers to the topic being studied, outlines its key focus areas, and helps establish a clear context for the study.
- Existing Knowledge: Here, researchers are required to provide a brief outline of existing knowledge drawn from seminal works, recent research findings, and ongoing debates and highlight gaps in the literature, demonstrating their awareness of existing scholarship.
- Detailed Bibliography: A detailed bibliography not only reflects the thoroughness of the literature review but also provides credibility to the proposed study. It allows reviewers to assess the quality and relevance of sources and enables them to gauge the scholarly merit of the PhD proposal.
- Research Methodology: Details of a comprehensive plan outlining the methodology, procedures, and techniques that will be employed to address the research objectives are included here. Methodology includes information on any special facilities, resources, or equipment required for data collection, analysis, or experimentation.
- Research Plan: This section provides a structured outline of the tasks and activities to be undertaken, along with their respective deadlines or milestones. It includes key phases such as literature review, data collection, analysis, and writing up the findings.
How Long Should a PhD Research Proposal be?
A research proposal typically spans approximately 2,500 words, although there is flexibility in the length as there is no strict upper or lower limit. However, the length may vary depending on the requirements of the institution or funding agency.
Tips for Writing Your PhD Research Proposal
Now that you understand the structure of a PhD research proposal , here are some tips to help you craft a compelling document: [7]
- Start early: Begin drafting your research proposal well in advance to allow yourself ample time for revisions and refinement.
- Be specific: Provide clear and detailed explanations of your objectives, methodology, and expected outcomes.
- Seek feedback: Share your proposal with peers or advisors to receive constructive feedback and suggestions for improvement.
- Write clearly and concisely: Use clear and concise language to convey your ideas effectively, avoiding unnecessary jargon or technical terms.
- Be ethical: Address any ethical considerations related to your research, such as participant consent or data privacy.
- Revise and proofread: Take time to revise, proofread and proofread again. Best to weed out any inconsistencies and errors for a favourable impression and to clearly communicate your ideas.
- Be passionate: Clearly convey your enthusiasm for the research topic and potential impact of your proposed study. Let your passion for your research topic shine through your proposal.

he simplest thing of all—structure. Everything you write has three components: a beginning, a middle and an e. d and each serves a different purpose. In practice, this means your review will have an introduction, a main body where you review the literature an. a conclusion where you tie things up.
The process of writing a literature review is different to that of writing the bulk of the dissertation itself. The aim at this point isn't necessarily to illustrate your own original ideas and research - that's what the dissertation is for - but rather to show the depth of your knowledge of the field and your ability to assess the work of other scholars.
A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays).
The key here is to focus first on the literature relevant to the puzzle. In this example, the tokenism literature sets up a puzzle derived from a theory and contradictory empirical evidence. Let's consider what each of these means... The literature(s) from which you develop the theoretical/empirical puzzle that drives your research question.
Step 1: Find the relevant literature. Naturally, the first step in the literature review journey is to hunt down the existing research that's relevant to your topic. While you probably already have a decent base of this from your research proposal, you need to expand on this substantially in the dissertation or thesis itself.. Essentially, you need to be looking for any existing literature ...
Demonstrate your knowledge of the research topic. Identify the gaps in the literature and show how your research links to these. Provide the foundation for your conceptual framework (if you have one) Inform your own methodology and research design. To achieve this, your literature review needs a well-thought-out structure.

Three sections of the thesis are analysed to show the: relationship between the introduction and the literature review. structure and purpose of dedicated literature review chapters.
The word "literature review" can refer to two related things that are part of the broader literature review process. The first is the task of reviewing the literature - i.e. sourcing and reading through the existing research relating to your research topic. The second is the actual chapter that you write up in your dissertation, thesis or ...
Preparing to Write . The literature review is more than just a list of previous research papers in the field. If you think of writing a thesis or dissertation as writing a story of your research, the literature review then will be a story within a story.

Okay, perhaps that's a bit much. Let me rephrase: Conducting a PhD literature review isn't as hard as you think. What a PhD literature review isn't. Let us make one thing very clear. A PhD literature review isn't just a summary of existing literature. That's an annotated bibliography and that isn't what a PhD literature review is about.
4. Consider the organisation of your work. In a dissertation literature review, organising your work goes beyond having an introduction, body and conclusion. You'll be reviewing a number of texts, so you'll also have to think clearly about how to organise themes, topics and your argument in general.
