Consider your specific area of study. Think about what interests you and what interests other researchers in your field.

Talk to your professor, brainstorm, and read lecture notes and recent issues of periodicals in the field.

Limit your scope to a smaller topic area (ie. focusing on France's role in WWII instead of focusing on WWII in general).

• Four Steps to Narrow Your Research Topic (Video) This 3-minute video provides instructions on how to narrow the focus of your research topic.
• Developing a Research Question + Worksheet Use this worksheet to develop, assess, and refine your research questions. There is also a downloadable PDF version.

Define your source selection criteria (ie. articles published between a specific date range, focusing on a specific geographic region, or using a specific methodology).

Using keywords, search a library database.

Reference lists of recent articles and reviews can lead to other useful papers.

Include any studies contrary to your point of view.

Evaluate and synthesize the studies' findings and conclusions.

Note the following:

• Assumptions some or most researchers seem to make
• Methodologies, testing procedures, subjects, material tested researchers use
• Experts in the field: names/labs that are frequently referenced
• Conflicting theories, results, methodologies
• Popularity of theories and how this has/has not changed over time
• Findings that are common/contested
• Important trends in the research
• The most influential theories

Tip: If your literature review is extensive, find a large table surface, and on it place post-it notes or filing cards to organize all your findings into categories.

• Move them around if you decide that (a) they fit better under different headings, or (b) you need to establish new topic headings.
• Develop headings/subheadings that reflect the major themes and patterns you detected

Write a one or two sentence statement summarizing the conclusion you have reached about the major trends and developments you see in the research that has been conducted on your subject.

• Templates for Writing Thesis Statements This template provides a two-step guide for writing thesis statements. There is also a downloadable PDF version.
• 5 Types of Thesis Statements Learn about five different types of thesis statements to help you choose the best type for your research. There is also a downloadable PDF version.
• 5 Questions to Strengthen Your Thesis Statement Follow these five steps to strengthen your thesis statements. There is also a downloadable PDF version.

Follow the organizational structure you developed above, including the headings and subheadings you constructed.

Make certain that each section links logically to the one before and after.

Structure your sections by themes or subtopics, not by individual theorists or researchers.

• Tip: If you find that each paragraph begins with a researcher's name, it might indicate that, instead of evaluating and comparing the research literature from an analytical point of view, you have simply described what research has been done.

Prioritize analysis over description.

• For example, look at the following two passages and note that Student A merely describes the literature, whereas Student B takes a more analytical and evaluative approach by comparing and contrasting. You can also see that this evaluative approach is well signaled by linguistic markers indicating logical connections (words such as "however," "moreover") and phrases such as "substantiates the claim that," which indicate supporting evidence and Student B's ability to synthesize knowledge.

Student A: Smith (2000) concludes that personal privacy in their living quarters is the most important factor in nursing home residents' perception of their autonomy. He suggests that the physical environment in the more public spaces of the building did not have much impact on their perceptions. Neither the layout of the building nor the activities available seem to make much difference. Jones and Johnstone make the claim that the need to control one's environment is a fundamental need of life (2001), and suggest that the approach of most institutions, which is to provide total care, may be as bad as no care at all. If people have no choices or think that they have none, they become depressed.

Student B: After studying residents and staff from two intermediate care facilities in Calgary, Alberta, Smith (2000) came to the conclusion that except for the amount of personal privacy available to residents, the physical environment of these institutions had minimal if any effect on their perceptions of control (autonomy). However, French (1998) and Haroon (2000) found that availability of private areas is not the only aspect of the physical environment that determines residents' autonomy. Haroon interviewed 115 residents from 32 different nursing homes known to have different levels of autonomy (2000). It was found that physical structures, such as standardized furniture, heating that could not be individually regulated, and no possession of a house key for residents limited their feelings of independence. Moreover, Hope (2002), who interviewed 225 residents from various nursing homes, substantiates the claim that characteristics of the institutional environment such as the extent of resources in the facility, as well as its location, are features which residents have indicated as being of great importance to their independence.

• How to Integrate Critical Voice into Your Literature Review (Video)
• Look at the topic sentences of each paragraph. If you were to read only these sentences, would you find that your paper presented a clear position, logically developed, from beginning to end? The topic sentences of each paragraph should indicate the main points of your literature review.
• Make an outline of each section of the paper and decide whether you need to add information, to delete irrelevant information, or to re-structure sections.
• Read your work out loud. That way you will be better able to identify where you need punctuation marks to signal pauses or divisions within sentences, where you have made grammatical errors, or where your sentences are unclear.
• Since the purpose of a literature review is to demonstrate that the writer is familiar with the important professional literature on the chosen subject, check to make certain that you have covered all of the important, up-to-date, and pertinent texts. In the sciences and some of the social sciences it is important that your literature be quite recent; this is not so important in the humanities.
• Make certain that all of the citations and references are correct and that you are referencing in the appropriate style for your discipline. If you are uncertain which style to use, ask your professor.
• Check to make sure that you have not plagiarized either by failing to cite a source of information, or by using words quoted directly from a source. (Usually if you take three or more words directly from another source, you should put those words within quotation marks, and cite the page.)
• Text should be written in a clear and concise academic style; it should not be descriptive in nature or use the language of everyday speech.
• There should be no grammatical or spelling errors.
• Sentences should flow smoothly and logically.

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.

• Quick Run-through
• Step 1 & 2

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.

Proofread my paper

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.

Receive feedback on language, structure, and formatting

Professional editors proofread and edit your paper by focusing on:

• Academic style
• Vague sentences
• Style consistency

See an example

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 .

Writing a Research Literature Review? — Here are tips to guide you through!

Literature review is both a process and a product. It involves searching within a defined source of information related to your research topic and then creating a comprehensive summary of the pertinent research on your topic. It is most certainly over a topic that has further scope for developing a research question .

Often, early career researchers find writing a literature review difficult and are unsure about the best way to structure their review and produce an effective research literature review. To make this process simpler, it is important that researchers understand the concept of literature review and the purpose behind it.

This article explains what a literature review is and how one can write an effective research literature review with the help of literature review examples.

Research Literature Review in Academia

If you are proposing a research topic that has a substantial amount of previously published work already, the prospect of delivering a good literature review can be a daunting task because a researcher will not only have to refer to journals, books, and articles, but also cite them!

In simpler words, a literature review is a critical collation of data from different sources relevant to your topic of research.

What Are the Four Major Types of Literature Reviews?

Based on their structure and formulation, literature reviews are broadly classified as-

1. Narrative or Traditional Literature Reviews

A narrative or traditional literature review is a comprehensive, critical, and objective analysis of existing knowledge of the topic. Literature review is an essential part of the research process because it helps establish theoretical framework and context for research study.

2. Scoping Reviews

A scoping review aims to identify the nature and extent of research evidence. As its name suggests, a scoping review is an ideal tool to determine the scope of literature on a given research topic.

3. Systematic Literature Reviews

A systematic literature review identifies and helps select research in order to answer a clearly formulated research question. Furthermore, a systematic review follows a defined protocol or plan where the criteria is clearly stated before the review is conducted.

4. Cochrane Reviews

Cochrane reviews are gold standard reviews; which are clearly reported and methodically better than systematic reviews. Moreover, this review systematically compares the risk of bias (RoB) in Cochrane and non-Cochrane systematic reviews using the dataset compiled in their database.

Outline of a Research Literature Review

Irrespective of the type of literature review, the three main components remain constant. A good research literature review consists of:

• Introduction
• The body of the literature review

Keeping these components in mind, the length of a literature review is not restricted to a word limit. It differs with respect to its purpose, audience, and discipline. Ideally, a research literature review written for a dissertation or thesis can be constructed into a full-length chapter of 20 pages.

What Is the Purpose of a Literature Review?

You may be tempted to save time by restricting your review to the last moment, but this can be a critical failure point. The purpose of writing a literature review is to establish your authority in your research. Without that established authority, your research findings are dismissed as nothing but your opinions founded on some basic methodologies.

What Should Not Be Included in a Literature Review?

A poorly executed scientific literature review can destroy a research thesis in four ways:

• If you can’t demonstrate that you have done the background work, you have no credibility as a researcher to recommend future research.
• If you haven’t mapped out the depth and breadth of the currently available material, you have no way to develop a cogent structure for the material you want to present as the foundation for your work.
• In the absence of a comprehensive summary of the material, you have no way to justify the position of your proposed research. Are you filling an identified gap, addressing identified weaknesses in someone else’s work, or perhaps extending an existing study to a broader or new population sample?
• If your research literature review isn’t comprehensive, you lose context when attempting to critique any of the previously published material.

Tips to Write a Good Literature Review

To write a good scientific literature review , you have to begin with a clear understanding of the role it plays in executing a thorough review for academic research:

• Context – where does your research project fit into the overall body of knowledge?
• Make a list of keywords to search your sources relevant to your research question
• Identify the key concepts/variables that apply in this area of research
• Identify the relationships between those concepts/variables
• Establish the need for further research – inconsistencies, lacking evidence, opportunities for further development, or alternative methodologies.

Refer to the literature review example for a better understanding.

Points To Remember

Demonstrate command of the material.

It’s not about maximizing the quantity of material reviewed , nor should the objective be to read “everything” about your proposed topic – for some topics that would be a physical impossibility.

Focus on the relevance of the material to your proposed topic , and map out a logical framework for analyzing that material. Develop relationships that make sense within that framework and organize your review around ideas not tenuous links by researcher or subject or chronology.

Don’t Ever Try to Fake It

Only include the material that you actually read – cutting and pasting someone else’s bibliography will come back to bite you later – especially if you have to do an oral defense and someone asks for your thoughts on a specific article or study.

Remember that just having read a dissertation or conference paper doesn’t count – you must critique it – what worked, what didn’t, and what would you do differently?

It’s All About Making Sense

Your reader should reach the end of your research literature review with a sense of full comprehension as to how your proposed study fits together with the current body of published work:

• You’re attempting to fill an identified gap
• You’re proposing to address an identified shortcoming
• You’re revisiting an inconclusive research summary
• You’re challenging an established theory
• You’re developing a limited study in more detail.

A complete guide on how to write a literature review

Table of Contents

A literature review is much more than just another section in your research paper. It forms the very foundation of your research. It is a formal piece of writing where you analyze the existing theoretical framework, principles, and assumptions and use that as a base to shape your approach to the research question.

Curating and drafting a solid literature review section not only lends more credibility to your research paper but also makes your research tighter and better focused. But, writing literature reviews is a difficult task. It requires extensive reading, plus you have to consider market trends and technological and political changes, which tend to change in the blink of an eye.

Now streamline your literature review process with the help of SciSpace Copilot. With this AI research assistant, you can efficiently synthesize and analyze a vast amount of information, identify key themes and trends, and uncover gaps in the existing research. Get real-time explanations, summaries, and answers to your questions for the paper you're reviewing, making navigating and understanding the complex literature landscape easier.

In this comprehensive guide, we will explore everything from the definition of a literature review, its appropriate length, various types of literature reviews, and how to write one.

What is a literature review?

A literature review is a collation of survey, research, critical evaluation, and assessment of the existing literature in a preferred domain.

Eminent researcher and academic Arlene Fink, in her book Conducting Research Literature Reviews , defines it as the following:

“A literature review surveys books, scholarly articles, and any other sources relevant to a particular issue, area of research, or theory, and by so doing, provides a description, summary, and critical evaluation of these works in relation to the research problem being investigated.

Literature reviews are designed to provide an overview of sources you have explored while researching a particular topic, and to demonstrate to your readers how your research fits within a larger field of study.”

Simply put, a literature review can be defined as a critical discussion of relevant pre-existing research around your research question and carving out a definitive place for your study in the existing body of knowledge. Literature reviews can be presented in multiple ways: a section of an article, the whole research paper itself, or a chapter of your thesis.

A literature review does function as a summary of sources, but it also allows you to analyze further, interpret, and examine the stated theories, methods, viewpoints, and, of course, the gaps in the existing content.

As an author, you can discuss and interpret the research question and its various aspects and debate your adopted methods to support the claim.

What is the purpose of a literature review?

A literature review is meant to help your readers understand the relevance of your research question and where it fits within the existing body of knowledge. As a researcher, you should use it to set the context, build your argument, and establish the need for your study.

What is the importance of a literature review?

The literature review is a critical part of research papers because it helps you:

• Gain an in-depth understanding of your research question and the surrounding area
• Convey that you have a thorough understanding of your research area and are up-to-date with the latest changes and advancements
• Establish how your research is connected or builds on the existing body of knowledge and how it could contribute to further research
• Elaborate on the validity and suitability of your theoretical framework and research methodology
• Identify and highlight gaps and shortcomings in the existing body of knowledge and how things need to change
• Convey to readers how your study is different or how it contributes to the research area

How long should a literature review be?

Ideally, the literature review should take up 15%-40% of the total length of your manuscript. So, if you have a 10,000-word research paper, the minimum word count could be 1500.

Your literature review format depends heavily on the kind of manuscript you are writing — an entire chapter in case of doctoral theses, a part of the introductory section in a research article, to a full-fledged review article that examines the previously published research on a topic.

Another determining factor is the type of research you are doing. The literature review section tends to be longer for secondary research projects than primary research projects.

What are the different types of literature reviews?

All literature reviews are not the same. There are a variety of possible approaches that you can take. It all depends on the type of research you are pursuing.

Here are the different types of literature reviews:

Argumentative review

It is called an argumentative review when you carefully present literature that only supports or counters a specific argument or premise to establish a viewpoint.

Integrative review

It is a type of literature review focused on building a comprehensive understanding of a topic by combining available theoretical frameworks and empirical evidence.

Methodological review

This approach delves into the ''how'' and the ''what" of the research question —  you cannot look at the outcome in isolation; you should also review the methodology used.

Systematic review

This form consists of an overview of existing evidence pertinent to a clearly formulated research question, which uses pre-specified and standardized methods to identify and critically appraise relevant research and collect, report, and analyze data from the studies included in the review.

Meta-analysis review

Meta-analysis uses statistical methods to summarize the results of independent studies. By combining information from all relevant studies, meta-analysis can provide more precise estimates of the effects than those derived from the individual studies included within a review.

Historical review

Historical literature reviews focus on examining research throughout a period, often starting with the first time an issue, concept, theory, or phenomenon emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and identify future research's likely directions.

Theoretical Review

This form aims to examine the corpus of theory accumulated regarding an issue, concept, theory, and phenomenon. The theoretical literature review helps to establish what theories exist, the relationships between them, the degree the existing approaches have been investigated, and to develop new hypotheses to be tested.

Scoping Review

The Scoping Review is often used at the beginning of an article, dissertation, or research proposal. It is conducted before the research to highlight gaps in the existing body of knowledge and explains why the project should be greenlit.

State-of-the-Art Review

The State-of-the-Art review is conducted periodically, focusing on the most recent research. It describes what is currently known, understood, or agreed upon regarding the research topic and highlights where there are still disagreements.

Can you use the first person in a literature review?

When writing literature reviews, you should avoid the usage of first-person pronouns. It means that instead of "I argue that" or "we argue that," the appropriate expression would be "this research paper argues that."

Do you need an abstract for a literature review?

Ideally, yes. It is always good to have a condensed summary that is self-contained and independent of the rest of your review. As for how to draft one, you can follow the same fundamental idea when preparing an abstract for a literature review. It should also include:

• The research topic and your motivation behind selecting it
• A one-sentence thesis statement
• An explanation of the kinds of literature featured in the review
• Summary of what you've learned
• Conclusions you drew from the literature you reviewed
• Potential implications and future scope for research

Is a literature review written in the past tense?

Yes, the literature review should ideally be written in the past tense. You should not use the present or future tense when writing one. The exceptions are when you have statements describing events that happened earlier than the literature you are reviewing or events that are currently occurring; then, you can use the past perfect or present perfect tenses.

How many sources for a literature review?

There are multiple approaches to deciding how many sources to include in a literature review section. The first approach would be to look level you are at as a researcher. For instance, a doctoral thesis might need 60+ sources. In contrast, you might only need to refer to 5-15 sources at the undergraduate level.

The second approach is based on the kind of literature review you are doing — whether it is merely a chapter of your paper or if it is a self-contained paper in itself. When it is just a chapter, sources should equal the total number of pages in your article's body. In the second scenario, you need at least three times as many sources as there are pages in your work.

Six quick tips on how to write a literature review

To know how to write a literature review, you must clearly understand its impact and role in establishing your work as substantive research material.

You need to follow the below-mentioned steps, to write a literature review:

• Outline the purpose behind the literature review
• Search relevant literature
• Examine and assess the relevant resources
• Discover connections by drawing deep insights from the resources
• Structure planning
• Write a good literature review

1. Outline and identify the purpose of  a literature review

As a first step on how to write a literature review, you must know what the research question or topic is and what shape you want your literature review to take. Ensure you understand the research topic inside out, or else seek clarifications. You must be able to the answer below questions before you start:

• How many sources do I need to include?
• What kind of sources should I analyze?
• How much should I critically evaluate each source?
• Should I summarize, synthesize or offer a critique of the sources?
• Do I need to include any background information or definitions?

Additionally, you should know that the narrower your research topic is, the swifter it will be for you to restrict the number of sources to be analyzed.

2. Search relevant literature

Dig deeper into search engines to discover what has already been published around your chosen topic. Make sure you thoroughly go through appropriate reference sources like books, reports, journal articles, government docs, and web-based resources.

You must prepare a list of keywords and their different variations. You can start your search from any library’s catalog, provided you are an active member of that institution. The exact keywords can be extended to widen your research over other databases and academic search engines like:

• Google Scholar
• Microsoft Academic
• Science.gov

Besides, it is not advisable to go through every resource word by word. Alternatively, what you can do is you can start by reading the abstract and then decide whether that source is relevant to your research or not.

Additionally, you must spend surplus time assessing the quality and relevance of resources. It would help if you tried preparing a list of citations to ensure that there lies no repetition of authors, publications, or articles in the literature review.

3. Examine and assess the sources

It is nearly impossible for you to go through every detail in the research article. So rather than trying to fetch every detail, you have to analyze and decide which research sources resemble closest and appear relevant to your chosen domain.

While analyzing the sources, you should look to find out answers to questions like:

• What question or problem has the author been describing and debating?
• What is the definition of critical aspects?
• How well the theories, approach, and methodology have been explained?
• Whether the research theory used some conventional or new innovative approach?
• How relevant are the key findings of the work?
• In what ways does it relate to other sources on the same topic?
• What challenges does this research paper pose to the existing theory
• What are the possible contributions or benefits it adds to the subject domain?

Be always mindful that you refer only to credible and authentic resources. It would be best if you always take references from different publications to validate your theory.

Always keep track of important information or data you can present in your literature review right from the beginning. It will help steer your path from any threats of plagiarism and also make it easier to curate an annotated bibliography or reference section.

4. Discover connections

At this stage, you must start deciding on the argument and structure of your literature review. To accomplish this, you must discover and identify the relations and connections between various resources while drafting your abstract.

A few aspects that you should be aware of while writing a literature review include:

• Rise to prominence: Theories and methods that have gained reputation and supporters over time.
• Constant scrutiny: Concepts or theories that repeatedly went under examination.
• Contradictions and conflicts: Theories, both the supporting and the contradictory ones, for the research topic.
• Knowledge gaps: What exactly does it fail to address, and how to bridge them with further research?
• Influential resources: Significant research projects available that have been upheld as milestones or perhaps, something that can modify the current trends

Once you join the dots between various past research works, it will be easier for you to draw a conclusion and identify your contribution to the existing knowledge base.

5. Structure planning for a literature review

There exist different ways towards planning and executing the structure of a literature review. The format of a literature review varies and depends upon the length of the research.

Nevertheless, a good literature review can be structured according to the chronological, thematic, methodological, or theoretical framework approach.

a) Chronological

The chronological approach to building the structure of a literature review has been described as one of the most straightforward approaches. However, do not just make a list or summarize the reference resources. Instead, try to put in a brief discussion and analysis of the critical arguments, research, and trends that have shaped the current status of your subject domain. Additionally, you must provide an interpretation of these events in your curated version.

b) Thematic

The format of a literature review is structured in sections and sub-sections. Every part stays dedicated to presenting a different aspect of your chosen topic. Unlike the chronological approach, the primary focus here is on a topic or issue instead of the progression of certain events.

c) Methodological

You can present your structure in a form by showing a comparison between crucial findings, gatherings, and outcomes from different research methods. These portions may include drawing insights and analysis of:

• Gatherings extracted from qualitative vs. quantitative methods.
• Leveraging the empirical and theoretical methods to validate your key findings and results.
• Classification of resources based upon the context of history, culture, and economy.

d) Theoretical

Literature reviews are often used to discuss and analyze vital concepts and theories. Adopting this approach, you can significantly put forth the relevance and critical findings of a particular theoretical method. Proceeding in the same way, you can also outline an entirely new research framework.

6. Write a good literature review

Like any other research paper, the literature review format must contain three sections: introduction, body, and conclusion. The goals and objectives of the research question determine what goes inside these three sections.

a) Introduction for a good literature review

Since it happens to be the first paragraph, you must include and define its purpose and critical aspects.

If you are writing the literature review for your thesis or dissertation, you should restate the research question. Likewise, you can even go towards presenting a summary of the whole context and highlighting the gaps existing within.

Besides, if you are writing the literature review as a separate assignment, you must choose to provide a piece of background information. Additionally, you must state its scope and objectives. However, in any case, do not skip mentioning results that you intend to draw from the literature.

b) Body of the literature review

To write a good literature review, the format and structure of the central body part play a pivotal role. Thus, you must use sections and subsections to divide the body for each methodological approach or theme aspect.

While writing the literature review, you can choose to adopt either or all of the following measures:

• A general overview or summary must be provided, focusing on the critical points of each source and coherent sync among all the references.
• It would be best to put your interpretations towards every source you opted to include. Paraphrasing others' work is something you should avoid altogether.
• Justify and validate your results per your research.
• Be specific about the strengths and weaknesses of specified sources.
• Transitions and topic sentences can be advantageous while writing nicely oriented body paragraphs.

c) Conclusion of the literature review

The conclusion of your literature review must be focused on your key findings, their results, and an elaborated emphasis on the significance of all aspects.

Describing the research gaps and your contributions can be helpful in case you are writing for a dissertation or thesis. Moreover, you must specify the procedure and research methodology for developing the framework for your research topic.

Additionally, if the literature review is a standalone assignment for you, present the conclusion centered on the implications and suggestions for future references.

Lastly, you must ensure that your research paper does not miss any critical aspects and must not contain any grammatical or spelling mistakes. For this, you must proofread and edit it to perfection.

What is a literature review.

A literature review is a summary of the published work in a field of study. This can be a section of a larger paper or article, or can be the focus of an entire paper. Literature reviews show that you have examined the breadth of knowledge and can justify your thesis or research questions. They are also valuable tools for other researchers who need to find a summary of that field of knowledge.

Unlike an annotated bibliography, which is a list of sources with short descriptions, a literature review synthesizes sources into a summary that has a thesis or statement of purpose—stated or implied—at its core.

How do I write a literature review?

Step 1: define your research scope.

• What is the specific research question that your literature review helps to define?
• Are there a maximum or minimum number of sources that your review should include?

Ask us if you have questions about refining your topic, search methods, writing tips, or citation management.

Step 2: Identify the literature

Start by searching broadly. Literature for your review will typically be acquired through scholarly books, journal articles, and/or dissertations. Develop an understanding of what is out there, what terms are accurate and helpful, etc., and keep track of all of it with citation management tools . If you need help figuring out key terms and where to search, ask us .

Use citation searching to track how scholars interact with, and build upon, previous research:

• Mine the references cited section of each relevant source for additional key sources
• Use Google Scholar or Scopus to find other sources that have cited a particular work

Step 3: Critically analyze the literature

Key to your literature review is a critical analysis of the literature collected around your topic. The analysis will explore relationships, major themes, and any critical gaps in the research expressed in the work. Read and summarize each source with an eye toward analyzing authority, currency, coverage, methodology, and relationship to other works. The University of Toronto's Writing Center provides a comprehensive list of questions you can use to analyze your sources.

Step 4: Categorize your resources

Divide the available resources that pertain to your research into categories reflecting their roles in addressing your research question. Possible ways to categorize resources include organization by:

• methodology
• theoretical/philosophical approach

Regardless of the division, each category should be accompanied by thorough discussions and explanations of strengths and weaknesses, value to the overall survey, and comparisons with similar sources. You may have enough resources when:

• You've used multiple databases and other resources (web portals, repositories, etc.) to get a variety of perspectives on the research topic.
• The same citations are showing up in a variety of databases.

How to Write a Successful Literature Review

One type of a proposal focus is a literature review/trend analysis . This type of a proposal is somewhat different from the other proposal foci. A sample literature/trend analysis is posted at the bottom of this guide.

A literature review surveys scholarly articles, books and other sources (e.g. dissertations, conference proceedings) relevant to a particular issue, area of research or theory, and provides a description, summary, and critical evaluation of these works.The goal of this form of a proposal is to provide an overview of the significant trends in the literature that is published on this topic.

The topics and references you include in your proposal should be purposeful and represent the key authors and arguments in that particular area of study. This necessitates that the review be consistently up to date and include the newest findings/discussions in that particular area of study or debate.

Definition and use/purpose

In a literature review you may highlight a critical area of a thesis, or it may be a focused, selected review of writings on a subject with the following purposes. Each work should:

• Relate to the context of its contribution to the understanding of the subject under review
• Describe / compare each work in relationship to the others in your proposal
• Identify new ways to interpret, and shed light on any gaps in, previous research
• Resolve conflicts among what is deemed as contradictory previous studies
• Identify areas of prior scholarship to prevent duplication of effort
• Illustrate how this work can be a starting point for further research
• Highlight the relevancy of the work in the context of existing literature

The literature review itself, however, does not present new primary scholarship.

What to include

• An overview of the subject, issue or theory under consideration, along with the objectives of the literature review
• Division of works under review into categories (e.g. those supporting a particular position, those who have the opposite view, and those who give alternative theses entirely)
• An explanation of how each work is similar to and how it varies from the others
• A conclusion . Determine which aspects are key in the debates on the topic, are most convincing, and make the greatest contribution to the understanding and development of this particular research area.

Evaluating the data

• Authority — What are the author's credentials? Is there evidence to support the author's arguments (e.g., primary historical material, case studies, narratives, statistics, recent scientific findings)?
• Objectivity — Does the author have a bias in the writing, or is the perspective even-handed? Does the author consider contrasting or opposing data or does he or she ignore other pertinent information in order to prove the author's point?
• Persuasiveness — Which of the author's theses are most/least convincing?
• Value — Does the author provide enough context to make the case that this is a relevant discussion in the current state of the field? Does this work make a significant contribution to create a stronger understanding of the subject?

Literature review

A general guide on how to conduct and write a literature review.

Please check course or programme information and materials provided by teaching staff , including your project supervisor, for subject-specific guidance.

What is a literature review?

A literature review is a piece of academic writing demonstrating knowledge and understanding of the academic literature on a specific topic placed in context.  A literature review also includes a critical evaluation of the material; this is why it is called a literature review rather than a literature report. It is a process of reviewing the literature, as well as a form of writing.

To illustrate the difference between reporting and reviewing, think about television or film review articles.  These articles include content such as a brief synopsis or the key points of the film or programme plus the critic’s own evaluation.  Similarly the two main objectives of a literature review are firstly the content covering existing research, theories and evidence, and secondly your own critical evaluation and discussion of this content. 

Usually a literature review forms a section or part of a dissertation, research project or long essay.  However, it can also be set and assessed as a standalone piece of work.

What is the purpose of a literature review?

…your task is to build an argument, not a library. Rudestam, K.E. and Newton, R.R. (1992) Surviving your dissertation: A comprehensive guide to content and process. California: Sage, p49.

In a larger piece of written work, such as a dissertation or project, a literature review is usually one of the first tasks carried out after deciding on a topic.  Reading combined with critical analysis can help to refine a topic and frame research questions.  Conducting a literature review establishes your familiarity with and understanding of current research in a particular field before carrying out a new investigation.  After doing a literature review, you should know what research has already been done and be able to identify what is unknown within your topic.

When doing and writing a literature review, it is good practice to:

• summarise and analyse previous research and theories;
• identify areas of controversy and contested claims;
• highlight any gaps that may exist in research to date.

A literature review explores and evaluates the literature on a specific topic or question. It synthesises the contributions of the different authors, often to identify areas that need further exploration.

You may be required to write a literature review as a standalone document or part of a larger body of research, such as a thesis.

• The point of a standalone literature review is to demonstrate that you have read widely in your field and you understand the main arguments.
• As part of a thesis or research paper, the literature review defines your project by establishing how your work will extend or differ from previous work and what contribution it will make.

What are markers looking for?

In the best literature reviews, the writer:

• Has a clear understanding of key concepts within the topic.
• Clarifies important definitions and terminology.
• Covers the breadth of the specific topic.
• Critically discusses the ideas in the literature and evaluates how authors present them.
• Clearly indicates a research gap for future enquiry.

Tips for research, reading and writing

You may be given a specific question to research or broad topics which must be refined to a question that can be reasonably addressed in the time and word limit available.

Use your early reading to help you determine and refine your topic.

• Too much literature? You probably need to narrow your scope. Try to identify a more specific issue of interest.
• Not enough literature? Your topic may be too specific and needs to be broader.

Start with readings suggested by your lecturers or supervisors. Then, do your own research - the best place to go is the Library Website .

You can also use the Library Guides or speak to a librarian to identify the most useful databases for you and to learn how to search for sources effectively and efficiently.

Cover the field

Make sure your literature search covers a broad range of views and information relevant to your topic. Focussing on a narrow selection of sources may result in a lack of depth. You are not expected to cover all research and scholarly opinions on your topic, but you need to identify and include important viewpoints. A quality literature review examines and evaluates different viewpoints based on the evidence presented, rather than providing only material that reinforces a bias.

Use reading strategies

Survey, skim and scan to find the most relevant articles, and the most relevant parts of those articles. These can be re-read more closely later when you have acquired an overview of your topic.

Take notes as you read

This helps to organise and develop your thoughts. Record your own reactions to the text in your notes, perhaps in a separate column. These notes can form the basis of your critical evaluation of the text. Record any facts, opinions or direct quotes that are likely to be useful to your review, noting the page numbers, author and year.

Stop reading when you have enough

This depends on the word count required of this literature review. A review of one thousand words can only cover the major ideas and probably less than ten references. Longer reviews that form part of a large research paper will include more than fifty. Your tutor or supervisor should be able to suggest a suitable number.

As you read, ask yourself these questions:

• Have I answered my question without any obvious gaps?
• Have I read this before? Are there any new related issues coming up as I search the literature?
• Have I found multiple references which cover the same material or just enough to prove agreement?

There are many possible ways to organise the material. For example:

• chronologically
• by theoretical perspective
• from most to least important
• by issue or theme

It is important to remember that you are not merely cataloguing or describing the literature you read. Therefore, you need to choose an organisation that will enable you to compare the various authors' treatment of ideas. This is often best achieved by organising thematically, or grouping ideas into sets of common issues tackled in the various texts. These themes will form the basis of the different threads that are the focus of your study.

A standalone literature review

A standalone literature review is structured much like an academic essay.

• Introduction - establish the context for your topic and outline your main contentions about the literature
• Main body - explain and support these inferences in the main body
• Conclusion - summarise your main points and restate the contention.

The main difference between an essay and this kind of literature review is that an essay focuses on a topic and uses the literature as a support for the arguments. In a standalone literature review, the literature itself is the topic of discussion and evaluation. This means you evaluate and discuss not only the informational content but the quality of the author’s handling of the content.

A literature review as part of a larger research paper?

As part of a larger research paper, the literature review may take many forms, depending on your discipline, your topic and the logic of your research. Traditionally, in empirical research, the literature review is included in the introduction, or a standalone chapter immediately following the introduction. For other forms of research, you may need to engage more extensively with the literature and thus, the literature review may spread over more than one chapter, or even be distributed throughout the thesis.

Start writing early. Writing will clarify your thinking on the topic and reveal any gaps in information and logic. If your ideas change, sections and paragraphs can be reworked to change your contentions or include extra information.

Similarly, draft an overall plan for your review as soon as you are ready, but be prepared to rework sections of it to reflect your developing argument.

The most important thing to remember is that you are writing a review . That means you must move past describing what other authors have written by connecting, interpreting and critiquing their ideas and presenting your own analysis and interpretation.
