Annotated Bibliographies

What this handout is about.

This handout will explain why annotated bibliographies are useful for researchers, provide an explanation of what constitutes an annotation, describe various types of annotations and styles for writing them, and offer multiple examples of annotated bibliographies in the MLA, APA, and CBE/CSE styles of citation.

Introduction

Welcome to the wonderful world of annotated bibliographies! You’re probably already familiar with the need to provide bibliographies, reference pages, and works cited lists to credit your sources when you do a research paper. An annotated bibliography includes descriptions and explanations of your listed sources beyond the basic citation information you usually provide.

Why do an annotated bibliography?

One of the reasons behind citing sources and compiling a general bibliography is so that you can prove you have done some valid research to back up your argument and claims. Readers can refer to a citation in your bibliography and then go look up the material themselves. When inspired by your text or your argument, interested researchers can access your resources. They may wish to double check a claim or interpretation you’ve made, or they may simply wish to continue researching according to their interests. But think about it: even though a bibliography provides a list of research sources of all types that includes publishing information, how much does that really tell a researcher or reader about the sources themselves?

An annotated bibliography provides specific information about each source you have used. As a researcher, you have become an expert on your topic: you have the ability to explain the content of your sources, assess their usefulness, and share this information with others who may be less familiar with them. Think of your paper as part of a conversation with people interested in the same things you are; the annotated bibliography allows you to tell readers what to check out, what might be worth checking out in some situations, and what might not be worth spending the time on. It’s kind of like providing a list of good movies for your classmates to watch and then going over the list with them, telling them why this movie is better than that one or why one student in your class might like a particular movie better than another student would. You want to give your audience enough information to understand basically what the movies are about and to make an informed decision about where to spend their money based on their interests.

What does an annotated bibliography do?

A good annotated bibliography:

• encourages you to think critically about the content of the works you are using, their place within a field of study, and their relation to your own research and ideas.
• proves you have read and understand your sources.
• establishes your work as a valid source and you as a competent researcher.
• situates your study and topic in a continuing professional conversation.
• provides a way for others to decide whether a source will be helpful to their research if they read it.
• could help interested researchers determine whether they are interested in a topic by providing background information and an idea of the kind of work going on in a field.

What elements might an annotation include?

• Bibliography according to the appropriate citation style (MLA, APA, CBE/CSE, etc.).
• Explanation of main points and/or purpose of the work—basically, its thesis—which shows among other things that you have read and thoroughly understand the source.
• Verification or critique of the authority or qualifications of the author.
• Comments on the worth, effectiveness, and usefulness of the work in terms of both the topic being researched and/or your own research project.
• The point of view or perspective from which the work was written. For instance, you may note whether the author seemed to have particular biases or was trying to reach a particular audience.
• Relevant links to other work done in the area, like related sources, possibly including a comparison with some of those already on your list. You may want to establish connections to other aspects of the same argument or opposing views.

The first four elements above are usually a necessary part of the annotated bibliography. Points 5 and 6 may involve a little more analysis of the source, but you may include them in other kinds of annotations besides evaluative ones. Depending on the type of annotation you use, which this handout will address in the next section, there may be additional kinds of information that you will need to include.

For more extensive research papers (probably ten pages or more), you often see resource materials grouped into sub-headed sections based on content, but this probably will not be necessary for the kinds of assignments you’ll be working on. For longer papers, ask your instructor about her preferences concerning annotated bibliographies.

Did you know that annotations have categories and styles?

Decisions, decisions.

As you go through this handout, you’ll see that, before you start, you’ll need to make several decisions about your annotations: citation format, type of annotation, and writing style for the annotation.

First of all, you’ll need to decide which kind of citation format is appropriate to the paper and its sources, for instance, MLA or APA. This may influence the format of the annotations and bibliography. Typically, bibliographies should be double-spaced and use normal margins (you may want to check with your instructor, since he may have a different style he wants you to follow).

MLA (Modern Language Association)

See the UNC Libraries citation tutorial for basic MLA bibliography formatting and rules.

• MLA documentation is generally used for disciplines in the humanities, such as English, languages, film, and cultural studies or other theoretical studies. These annotations are often summary or analytical annotations.
• Title your annotated bibliography “Annotated Bibliography” or “Annotated List of Works Cited.”
• Following MLA format, use a hanging indent for your bibliographic information. This means the first line is not indented and all the other lines are indented four spaces (you may ask your instructor if it’s okay to tab over instead of using four spaces).
• Begin your annotation immediately after the bibliographic information of the source ends; don’t skip a line down unless you have been told to do so by your instructor.

APA (American Psychological Association)

See the UNC Libraries citation tutorial for basic APA bibliography formatting and rules.

• Natural and social sciences, such as psychology, nursing, sociology, and social work, use APA documentation. It is also used in economics, business, and criminology. These annotations are often succinct summaries.
• Annotated bibliographies for APA format do not require a special title. Use the usual “References” designation.
• Like MLA, APA uses a hanging indent: the first line is set flush with the left margin, and all other lines are indented four spaces (you may ask your instructor if it’s okay to tab over instead of using four spaces).
• After the bibliographic citation, drop down to the next line to begin the annotation, but don’t skip an extra line.
• The entire annotation is indented an additional two spaces, so that means each of its lines will be six spaces from the margin (if your instructor has said that it’s okay to tab over instead of using the four spaces rule, indent the annotation two more spaces in from that point).

CBE (Council of Biology Editors)/CSE (Council of Science Editors)

See the UNC Libraries citation tutorial for basic CBE/CSE bibliography formatting and rules.

• CBE/CSE documentation is used by the plant sciences, zoology, microbiology, and many of the medical sciences.
• Annotated bibliographies for CBE/CSE format do not require a special title. Use the usual “References,” “Cited References,” or “Literature Cited,” and set it flush with the left margin.
• Bibliographies for CSE in general are in a slightly smaller font than the rest of the paper.
• When using the name-year system, as in MLA and APA, the first line of each entry is set flush with the left margin, and all subsequent lines, including the annotation, are indented three or four spaces.
• When using the citation-sequence method, each entry begins two spaces after the number, and every line, including the annotation, will be indented to match the beginning of the entry, or may be slightly further indented, as in the case of journals.
• After the bibliographic citation, drop down to the next line to begin the annotation, but don’t skip an extra line. The entire annotation follows the indentation of the bibliographic entry, whether it’s N-Y or C-S format.
• Annotations in CBE/CSE are generally a smaller font size than the rest of the bibliographic information.

After choosing a documentation format, you’ll choose from a variety of annotation categories presented in the following section. Each type of annotation highlights a particular approach to presenting a source to a reader. For instance, an annotation could provide a summary of the source only, or it could also provide some additional evaluation of that material.

In addition to making choices related to the content of the annotation, you’ll also need to choose a style of writing—for instance, telescopic versus paragraph form. Your writing style isn’t dictated by the content of your annotation. Writing style simply refers to the way you’ve chosen to convey written information. A discussion of writing style follows the section on annotation types.

Types of annotations

As you now know, one annotation does not fit all purposes! There are different kinds of annotations, depending on what might be most important for your reader to learn about a source. Your assignments will usually make it clear which citation format you need to use, but they may not always specify which type of annotation to employ. In that case, you’ll either need to pick your instructor’s brain a little to see what she wants or use clue words from the assignment itself to make a decision. For instance, the assignment may tell you that your annotative bibliography should give evidence proving an analytical understanding of the sources you’ve used. The word analytical clues you in to the idea that you must evaluate the sources you’re working with and provide some kind of critique.

Summary annotations

There are two kinds of summarizing annotations, informative and indicative.

Summarizing annotations in general have a couple of defining features:

• They sum up the content of the source, as a book report might.
• They give an overview of the arguments and proofs/evidence addressed in the work and note the resulting conclusion.
• They do not judge the work they are discussing. Leave that to the critical/evaluative annotations.
• When appropriate, they describe the author’s methodology or approach to material. For instance, you might mention if the source is an ethnography or if the author employs a particular kind of theory.

Informative annotation

Informative annotations sometimes read like straight summaries of the source material, but they often spend a little more time summarizing relevant information about the author or the work itself.

Indicative annotation

Indicative annotation is the second type of summary annotation, but it does not attempt to include actual information from the argument itself. Instead, it gives general information about what kinds of questions or issues are addressed by the work. This sometimes includes the use of chapter titles.

Critical/evaluative

Evaluative annotations don’t just summarize. In addition to tackling the points addressed in summary annotations, evaluative annotations:

• evaluate the source or author critically (biases, lack of evidence, objective, etc.).
• show how the work may or may not be useful for a particular field of study or audience.
• explain how researching this material assisted your own project.

Combination

An annotated bibliography may combine elements of all the types. In fact, most of them fall into this category: a little summarizing and describing, a little evaluation.

Writing style

Ok, next! So what does it mean to use different writing styles as opposed to different kinds of content? Content is what belongs in the annotation, and style is the way you write it up. First, choose which content type you need to compose, and then choose the style you’re going to use to write it

This kind of annotated bibliography is a study in succinctness. It uses a minimalist treatment of both information and sentence structure, without sacrificing clarity. Warning: this kind of writing can be harder than you might think.

Don’t skimp on this kind of annotated bibliography. If your instructor has asked for paragraph form, it likely means that you’ll need to include several elements in the annotation, or that she expects a more in-depth description or evaluation, for instance. Make sure to provide a full paragraph of discussion for each work.

As you can see now, bibliographies and annotations are really a series of organized steps. They require meticulous attention, but in the end, you’ve got an entire testimony to all the research and work you’ve done. At the end of this handout you’ll find examples of informative, indicative, evaluative, combination, telescopic, and paragraph annotated bibliography entries in MLA, APA, and CBE formats. Use these examples as your guide to creating an annotated bibliography that makes you look like the expert you are!

Definitions

A bibliography is a list of sources (books, journals, Web sites, periodicals, etc.) one has used for researching a topic. Bibliographies are sometimes called "References" or "Works Cited" depending on the style format you are using. A bibliography usually just includes the bibliographic information (i.e., the author, title, publisher, etc.).

An annotation is a summary and/or evaluation. Therefore, an annotated bibliography includes a summary and/or evaluation of each of the sources. Depending on your project or the assignment, your annotations may do one or more of the following.

For more help, see our handout on paraphrasing sources.

For more help, see our handouts on evaluating resources .

• Reflect : Once you've summarized and assessed a source, you need to ask how it fits into your research. Was this source helpful to you? How does it help you shape your argument? How can you use this source in your research project? Has it changed how you think about your topic?

Your annotated bibliography may include some of these, all of these, or even others. If you're doing this for a class, you should get specific guidelines from your instructor.

Why should I write an annotated bibliography?

To learn about your topic : Writing an annotated bibliography is excellent preparation for a research project. Just collecting sources for a bibliography is useful, but when you have to write annotations for each source, you're forced to read each source more carefully. You begin to read more critically instead of just collecting information. At the professional level, annotated bibliographies allow you to see what has been done in the literature and where your own research or scholarship can fit. To help you formulate a thesis: Every good research paper is an argument. The purpose of research is to state and support a thesis. So, a very important part of research is developing a thesis that is debatable, interesting, and current. Writing an annotated bibliography can help you gain a good perspective on what is being said about your topic. By reading and responding to a variety of sources on a topic, you'll start to see what the issues are, what people are arguing about, and you'll then be able to develop your own point of view.

To help other researchers : Extensive and scholarly annotated bibliographies are sometimes published. They provide a comprehensive overview of everything important that has been and is being said about that topic. You may not ever get your annotated bibliography published, but as a researcher, you might want to look for one that has been published about your topic.

The format of an annotated bibliography can vary, so if you're doing one for a class, it's important to ask for specific guidelines.

The bibliographic information : Generally, though, the bibliographic information of the source (the title, author, publisher, date, etc.) is written in either MLA or APA format. For more help with formatting, see our MLA handout . For APA, go here: APA handout .

The annotations: The annotations for each source are written in paragraph form. The lengths of the annotations can vary significantly from a couple of sentences to a couple of pages. The length will depend on the purpose. If you're just writing summaries of your sources, the annotations may not be very long. However, if you are writing an extensive analysis of each source, you'll need more space.

You can focus your annotations for your own needs. A few sentences of general summary followed by several sentences of how you can fit the work into your larger paper or project can serve you well when you go to draft.

Annotated Bibliography

An annotated bibliography is an organized list of sources, each of which is followed by a brief note or “annotation.”

These annotations do one or more of the following:

• describe the content and focus of the book or article
• suggest the source’s usefulness to your research
• evaluate its method, conclusions, or reliability
• record your reactions to the source.

How do I format the bibliographic citations?

Check with your instructor to determine which documentation style is required for your class: APA, MLA, Chicago/Turabian, CBE, Numbered References, APSA, etc.

Then, remember that the bibliography is an organized list of sources used. The annotation may immediately follow the bibliographic information on the same line, or it may begin on a new line, two lines below the publication information.

But, since style manuals differ, check with your instructor about which one to use concerning form, spacing, and consistency.

If you are using APA documentation, the Writing Center offers a short workshop called “APA Documentation”.

What goes into the content of the annotations?

Below are some of the most common forms of annotated bibliographies. Click on the links to see examples of each.

This form of annotation defines the scope of the source, lists the significant topics included, and tells what the source is about.

This type is different from the informative entry in that the informative entry gives actual information about its source.

In the indicative entry there is no attempt to give actual data such as hypotheses, proofs, etc. Generally, only topics or chapter titles are included.

Indicative (descriptive–tell us what is included in the source) Griffin, C. Williams, ed. (1982). Teaching writing in all disciplines. San Francisco: Jossey-Bass. Ten essays on writing-across-the-curriculum programs, teaching writing in disciplines other than English, and teaching techniques for using writing as learning. Essays include Toby Fulwiler, “Writing: An Act of Cognition”; Barbara King, “Using Writing in the Mathematics Class: Theory and Pratice”; Dean Drenk, “Teaching Finance Through Writing”; Elaine P. Maimon, “Writing Across the Curriculum: Past, Present, and Future.” (Bizzell and Herzberg, 1991, p. 47)

Informative

Simply put, this form of annotation is a summary of the source.

To write it, begin by writing the thesis; then develop it with the argument or hypothesis, list the proofs, and state the conclusion.

Informative (summary–tell us what the main findings or arguments are in the source) Voeltz, L.M. (1980). Children’s attitudes toward handicapped peers. American Journal of Mental Deficiency, 84, 455-464. As services for severely handicapped children become increasingly available within neighborhood public schools, children’s attitudes toward handicapped peers in integrated settings warrant attention. Factor analysis of attitude survey responses of 2,392 children revealed four factors underlying attitudes toward handicapped peers: social-contact willingness, deviance consequation, and two actual contact dimensions. Upper elementary-age children, girls, and children in schools with most contact with severely handicapped peers expressed the most accepting attitudes. Results of this study suggest the modifiability of children’s attitudes and the need to develop interventions to facilitate social acceptance of individual differences in integrated school settings. (Sternlicht and Windholz, 1984, p. 79)

In this form of annotation you need to assess the source’s strengths and weaknesses.

You get to say why the source is interesting or helpful to you, or why it is not. In doing this you should list what kind of and how much information is given; in short, evaluate the source’s usefulness.

Evaluative (tell us what you think of the source) Gurko, Leo. (1968). Ernest Hemingway and the pursuit of heroism. New York: Crowell. This book is part of a series called “Twentieth Century American Writers”: a brief introduction to the man and his work. After fifty pages of straight biography, Gurko discussed Hemingway’s writing, novel by novel. There’s an index and a short bibliography, but no notes. The biographical part is clear and easy to read, but it sounds too much like a summary. (Spatt, 1991, p. 322) Hingley, Ronald. (1950). Chekhov: A biographical and critical study. London: George Allen & Unwin. A very good biography. A unique feature of this book is the appendix, which has a chronological listing of all English translations of Chekhov’s short stories. (Spatt, 1991, p. 411)

Combination

Most annotated bibliographies are of this type.

They contain one or two sentences summarizing or describing content and one or two sentences providing an evaluation.

Combination Morris, Joyce M. (1959). Reading in the primary school: An investigation into standards of reading and their association with primary school characteristics. London: Newnes, for National Foundation for Educational Research. Report of a large-scale investigation into English children’s reading standards, and their relation to conditions such as size of classes, types of organisation and methods of teaching. Based on enquiries in sixty schools in Kent and covering 8,000 children learning to read English as their mother tongue. Notable for thoroughness of research techniques.

Which writing style should I use in the annotations?

The most important thing to understand is that entries should be brief.

Only directly significant details will be mentioned and any information apparent in the title can be omitted from the annotation.

In addition, background materials and references to previous work by the same author usually are not included.

Listed below are three writing styles used in annotated bibliographies. Click on a link to see examples of each.

Telegraphic

(phrases, non-sentences)

Get the information out, quickly and concisely. Be clear, but complete and grammatically correct sentences are unnecessary.

Telegraphic (phrases, non-sentences) Vowles, Richard B. (1962). Psychology and drama: A selected checklist. Wisconsin Studies in Contemporary Literature, 3,(1), 35-48. Divided by individual authors. Reviews the research between 1920 and 1961. (Bell and Gallup, 1971, p. 68)

Complete sentences

In this style you must always use complete sentences.

The length of the sentences varies. Subjects and conjunctions are not eliminated even though the tone may be terse. Avoid long and complex sentences.

Complete sentences Kinter, W. R., and R L. Pfaltzgraff. (1972). Assessing the Moscow SALT agreements. Orbis, 16, 34l-360. The authors hold the conservative view that SALT can not halt the slipping nuclear advantage of the United States. They conclude that the United States needs a national reassessment of defense policy. They further conclude that the only utility of SALT is in developing a dialogue with the Soviets. This is a good conservative critique of SALT I. (Strenski and Manfred, 1981, p. 165)

When using this form of annotation, you must write a full, coherent paragraph.

Sometimes this can be similar to the form of a bibliographic essay. It goes without saying that you need to use complete sentences.

Paragraph (a little more formal) Voeltz, L.M. (1980). Children’s attitudes toward handicapped peers. American Journal of Mental Deficiency, 84, 455-464. As services for severely handicapped children become increasingly available within neighborhood public schools, children’s attitudes toward handicapped peers in integrated settings warrant attention. Factor analysis of attitude survey responses of 2,392 children revealed four factors underlying attitudes toward handicapped peers: social- contact willingness, deviance consequation, and two actual contact dimensions. Upper elementary-age children, girls, and children in schools with most contact with severely handicapped peers expressed the most accepting attitudes. Results of this study suggest the modifiability of children’s attitudes and the need to develop interventions to facilitate social acceptance of individual differences in integrated school settings. (Sternlicht and Windholz, 1984, p. 79)

Additional information

If you have additional questions, ask your course instructor or consider scheduling an appointment with a Writing Center instructor.

The Writing Center also has information on different documentation systems, such as MLA, APA, Chicago/Turabian, CBE, Numbered References, and APSA styles of citation.

If you are using APA documentation, you are in luck! The Writing Center offers a short class called “The Basics of APA Documentation”!

What is an annotated bibliography .

An Annotated Bibliography is an APA Reference list of sources followed by notes and commentary about a source. The annotations summarize, assess, evaluate, and reflect on the information source.  

If we look at the word “annotate,” we are talking about “critical or explanatory notes” about the information source(s). “Bibliography” means “a list of information sources”. For an academic audience, annotations must be both critical and descriptive.   

Annotated Bibliography structure? 

So, if we could develop an anatomy of Annotated Bibliography we could break it into 3 parts: The summary, assess and evaluate, and reflection.  

For annotated bibliographies, use standard APA format for the citations, then add a brief entry, including: 

• What are the main arguments? 
• What is the point of the information source? 
• What topics are discussed? 
• How does it compare with other sources in your bibliography? 
• Is this information reliable? current? 
• Is the author credible?      
• Is the source objective or biased? 
• Was this source helpful to you? 
• How can you use this source for your research? 
• Has it changed how you think about your research topic?

What is an annotated bibliography?

An annotated bibliography gives an account of the research that has been done on a given topic. Like any bibliography, an annotated bibliography is an alphabetical list of research sources. In addition to bibliographic data, an annotated bibliography provides a concise summary of each source and some assessment of its value or relevance. Depending on your assignment, an annotated bibliography may be one stage in a larger research project, or it may be an independent project standing on its own.

Selecting the sources:

The quality and usefulness of your bibliography will depend on your selection of sources. Define the scope of your research carefully so that you can make good judgments about what to include and exclude. Your research should attempt to be reasonably comprehensive within well-defined boundaries. Consider these questions to help you find appropriate limits for your research:

• What problem am I investigating? What question(s) am I trying to pursue? If your bibliography is part of a research project, this project will probably be governed by a research question. If your bibliography is an independent project on a general topic (e.g. aboriginal women and Canadian law), try formulating your topic as a question or a series of questions in order to define your search more precisely ( e.g. How has Canadian law affecting aboriginal women changed as a result of the Charter of Rights and Freedoms? How have these changes affected aboriginal women? How have aboriginal women influenced and responded to these legal developments?).
• What kind of material am I looking for? (academic books and journal articles? government reports or policy statements? articles from the popular press? primary historical sources? etc.)
• Am I finding essential studies on my topic? (Read footnotes in useful articles carefully to see what sources they use and why. Keep an eye out for studies that are referred to by several of your sources.)

Summarizing the argument of a source:

An annotation briefly restates the main argument of a source. An annotation of an academic source, for example, typically identifies its thesis (or research question, or hypothesis), its major methods of investigation, and its main conclusions. Keep in mind that identifying the argument of a source is a different task than describing or listing its contents. Rather than listing contents (see Example 1 below), an annotation should account for why the contents are there (see Example 2 below).

Example 1: Only lists contents:

McIvor, S. D. (1995). Aboriginal women’s rights as “existing rights.” Canadian Woman Studies/Les Cahiers de la Femme 2/3 , 34-38. This article discusses recent constitutional legislation as it affects the human rights of aboriginal women in Canada: the Constitution Act (1982), its amendment in 1983, and amendments to the Indian Act (1985). It also discusses the implications for aboriginal women of the Supreme Court of Canada’s interpretation of the Constitution Act in R. v. Sparrow (1991).

Example 2: Identifies the argument:

McIvor, S. D. (1995). Aboriginal women’s rights as “existing rights.” Canadian Woman Studies/Les Cahiers de la Femme 2/3 , 34-38. This article seeks to define the extent of the civil and political rights returned to aboriginal women in the Constitution Act (1982), in its amendment in 1983, and in amendments to the Indian Act (1985). * This legislation reverses prior laws that denied Indian status to aboriginal women who married non-aboriginal men. On the basis of the Supreme Court of Canada’s interpretation of the Constitution Act in R. v. Sparrow (1991), McIvor argues that the Act recognizes fundamental human rights and existing aboriginal rights, granting to aboriginal women full participation in the aboriginal right to self-government. ** * research question ** method & main conclusions

The following reading strategies can help you identify the argument of your source:

• Identify the author’s thesis (central claim or purpose) or research question. Both the introduction and the conclusion can help you with this task.
• Look for repetition of key terms or ideas. Follow them through the text and see what the author does with them. Note especially the key terms that occur in the thesis or research question that governs the text.
• Notice how the text is laid out and organized. What are the main divisions or sections? What is emphasized? Why? Accounting for why will help you to move beyond listing contents and toward giving an account of the argument.
• Notice whether and how a theory is used to interpret evidence or data. Identify the method used to investigate the problem/s addressed in the text.
• Pay attention to the opening sentence(s) of each paragraph, where authors often state concisely their main point in the paragraph.
• Look for paragraphs that summarize the argument. A section may sometimes begin or conclude with such a paragraph.

Assessing the relevance and value of sources:

Your annotation should now go on to briefly assess the value of the source to an investigation of your research question or problem. If your bibliography is part of a research project, briefly identify how you intend to use the source and why. If your bibliography is an independent project, try to assess the source’s contribution to the research on your topic.

• Are you interested in the way the source frames its research question or in the way it goes about answering it (its method)? Does it make new connections or open up new ways of seeing a problem? (e.g. bringing the Sparrow decision concerning aboriginal fishing rights to bear on the scope of women’s rights)
• Are you interested in the way the source uses a theoretical framework or a key concept? (e.g. analysis of existing, extinguished, and other kinds of rights)
• Does the source gather and analyze a particular body of evidence that you want to use? (e.g. the historical development of a body of legislation)
• How do the source’s conclusions bear on your own investigation?

In order to determine how you will use the source or define its contribution, you will need to assess the quality of the argument: why is it of value? what are its limitations? how well defined is its research problem? how effective is its method of investigation? how good is the evidence? would you draw the same conclusions from the evidence?

Keep the context of your project in mind. How is material assessed in your course or discipline? What models for assessing arguments are available in course materials?

Various kinds of annotated bibliographies:

Annotated bibliographies do come in many variations. Pay close attention to the requirements of your assignment. Here are some possible variations:

• Some assignments may require you to summarize only and not to evaluate.
• Some assignments may want you to notice and comment on patterns of similarity and dissimilarity between sources; other assignments may want you to treat each source independently.
• If the bibliography is long, consider organizing it in sections. Your categories of organization should help clarify your research question.
• Some assignments may require or allow you to preface the bibliography (or its sections) with a paragraph explaining the scope of your investigation and providing a rationale for your selection of sources.

Some language for talking about texts and arguments:

It is sometimes challenging to find the vocabulary in which to summarize and discuss a text. Here is a list of some verbs for referring to texts and ideas that you might find useful:

Annotated Bibliography Format & Examples

A complete guide to the mla & apa annotated bibliography.

If you’ve just received an assignment that requires an MLA or APA annotated bibliography, you may be wondering where to start. This guide will help answer all of your questions and includes step-by-step instructions on how to do an annotated bibliography in MLA style, as well as an APA annotated bibliography. You will also find sample annotated bibliographies, real-life examples, and opportunities to practice what you have learned.

The MLA ( Modern Language Association ) and APA (American Psychological Association) are not associated with this guide. All of the information provided here, however, offers direction for students and researchers who use these citation styles in their work.

The structures and annotated bibliography templates on this page were created by the in-house librarians at EasyBib.com.

If you’re simply looking for an example of an annotated bibliography (both in MLA format and APA format), scroll down toward the bottom of the page. We’ve included links to visuals for those of you who need help with the structure and styling of an annotated bibliography. If you’re looking for a variety of annotated bibliography topics, and you’re truly searching for the answer to, “What is an annotated bibliography?” then continue reading!

A bibliography is a complete list of the sources that were used to complete a research paper or project.

Depending on the style guide you follow, you may also see this called a Works Cited (also called an MLA bibliography) or Reference List (APA format). Each listed source, or citation , shares information about the author, title, publishing year, and other details that serve to credit the original authors whose work informed your research. These details also help other students and researchers find and read the source materials.

When your research is related to a scholastic assignment, you should always verify your instructor’s requirements for the types and number of sources to include, as well as the style you should adhere to when formatting your paper and bibliography.

An MLA annotated bibliography and an APA format annotated bibliography are bibliographies that include a concise explanation, or annotation , of each listed source. Depending on the assignment, this annotation may be solely descriptive, or analytical.

An abstract and annotation should not be confused; they differ in both their substance as well as their placement in a paper.

Annotations: 

• Usually found in bibliographies at the end of a paper
• Are subjective
• Purpose is to summarize and evaluate . It should briefly communicate the work’s main point, but also discuss the background of the author or study, and the strengths/weaknesses of the work.

Abstracts: 

• Usually found in journal databases or the beginning of a paper
• Are objective
• Purpose is to summarize . It should provide a short overview of the article and communicate the main points and themes.

If you would like to learn more , this link further explores the difference between an abstract and an annotation.

Before you learn how to make an annotated bibliography, you may be wondering why you need to.

Sometimes instructors want you to create and include annotations in your bibliography, either as part of an assignment or as an assignment unto itself. Understanding the purpose of this approach to your reference list can help to ensure that you gain all of the benefits that the annotated bibliography process provides.

As a student, this method will help you develop or hone your research skills, providing you with practice not only in locating sources but also in analyzing and evaluating them for relevance and quality.

Your instructor will gain insight into your research abilities, as well, allowing them to assess your work more thoroughly. If you plan to publish your research, this comprehensive approach to detailing your sources will provide readers and other researchers with a substantial directory of resources to evaluate for their own work.

Whether you’re publishing or submitting your annotated bibliography, make sure your spelling and wording is correct! If you need to brush up on any parts of speech topics, check out our interjection , determiner , and adverb pages!

Step 1: Analyze your sources 

Each annotation should be a summarization or analysis of your source. If you have been tasked with writing annotations as part of a research paper or project, begin to create both the citation and notes on the source while you identify and analyze your sources.

Not only will this approach help you to hone your research skills and identify sources that are relevant and useful for your topic, but you will also save time. When done in this manner, both your citations and annotations will be nearly complete before you begin to write the body of your paper.

Analyzing your potential sources requires a two-pronged approach that first evaluates the author, publication, and date, and then examines the content.

When conducting your initial assessment of the source, consider some of the following questions to guide your appraisal:

• What qualifies the author to write on this subject?
• Is the author affiliated with a reputable institution in this field?
• Is the author credentialed or otherwise considered an expert in this field?
• Is this source current?
• Is this the most recent edition?
• Is the publisher reputable?
• Is the journal reputable?

Once your primary evaluation is complete, you will move on the assessing the content itself. Consider some of these elements as you review each source:

• Who is the intended audience?
• Is the author presenting her opinion or interpretation as the truth, or stating facts?
• What supporting evidence does the author provide?
• Did the author perform the research, or curate and present the research of others?
• If the author used the research of others, are the sources the author cites credible?
• Are there errors or omissions of fact?
• Is the author writing objectively and without bias?

Also, consider the value each source provides to you:

• Is the information helpful for your particular assignment?
• Does it help answer your research question(s)?
• Is this source different from your other sources, or does it repeat information you already have?
• Is the source providing you with a different perspective on your topic, or changing your beliefs or thinking about your subject?

To make it easier for you to create your reference page, write your notes in the format you will be using when you construct this part of the assignment (for instance, as short phrases or complete sentences). Once you have identified all of the sources you wish to include, you will merely need to insert what you have already written on the page and write your citation, which is explained in the next section.

Click here for additional information and a supplementary annotated bibliography sample. For an MLA bibliography example (with annotations),  check out our visual example of an MLA annotated bibliography .

An annotated bibliography entry may be written either as short phrases or complete sentences. Your instructor will advise you of which approach you are required to take.

Annotations should include either:

• The main points from the source, as well as the topics covered, the approach used, and any findings.
• Or your critical evaluation.
• A standard annotation is approximately one paragraph.
• Take care not to include any unnecessary details, as the goal is to summarize each source as succinctly as possible and, in some cases, evaluate them.
• Your field of study or instructor will determine what format your annotated bibliography will use. In this guide, you’ll find examples of an MLA and an APA annotated bibliography.

Here is an annotated bibliography example MLA annotation for the book The Elements of Eloquence: Secrets of the Perfect Turn of Phrase by UK author and blogger Mark Forsyth:

The author, Mark Forsyth, examines the rhetorical devices used in the English language, analyzing the patterns and formats that create memorable quotes. He traces the history of rhetoric to the Ancient Greeks, and provides an abridged timeline, following their use and evolution through to modern day. The author also explores the broader subject of persuasion and maps out the role that the figures of rhetoric play in it. In all, he examines over thirty devices, dissecting notable passages and phrases from pop music, the plays of William Shakespeare, the Bible, and more to explore the figures of rhetoric at work within each of them. Thorough definitions accompany this examination of structure to demonstrate how these formulas have been used to generate famously memorable expressions as well as how to reproduce their effects.

Notice how the annotated bibliography MLA entry above is descriptive enough so the reader has an idea of what the source is about with just a single paragraph. For more information on annotations, check out this informative site . If you’re looking to strengthen your writing in general, reading these grammar guides could be a good start.

For guidance on creating entries in MLA format , APA format , and more styles , check out the EasyBib library of resources or try the EasyBib annotation tool—we talk about it below!

Step 3a: MLA annotated bibliography format

The MLA Style Center and the current edition of the MLA Handbook provide the following guidance for formatting an MLA annotated bibliography:

• Title your reference page as “Annotated Bibliography” or “Annotated List of Works Cited.”
• Place each annotation after its reference.
• Annotations should typically not exceed a single paragraph.
• Annotations should be indented one inch from the start of your citation.
• Double-space all text on the page.
• 1-inch margins around the page.

Sources in an annotated bibliography can be organized alphabetically by the first word in each reference (as with a normal Works Cited page), by publication date, or by subject.

For a visual example of an annotated bibliography, as well as specific annotation examples, visit the MLA annotated bibliography guide .

If you are required to share your references in a manner other than in MLA bibliography format, the EasyBib style guides can help you with many common styles. While you’re at it, check out their conjunction , preposition , and pronoun pages to help keep your paper in mint condition!

Step 3b: APA annotated bibliography format

The American Psychological Association states that your instructor should set the guidelines for your annotated bibliography, but asks that the bibliography be formatted according to their standard reference page rules (see Section 9.51 of the Publication Manual ). If your teacher has requested an APA formatted annotated bibliography, first ask them for guidelines. Otherwise, here are some quick rules for you to follow:

• Double space all text on the page.  
• Title your page “Annotated Bibliogra phy”. Bold and center the title.  
• Organize references alphabetically by the first word of each reference.  
• Only the first line of a ref erence is flush with the left margin. Any other lines after the first line should be indented ½ inch from the left.  
• Add annotations on the next line after their paired reference.   
• Fully indent annotations by a ½ inch from the left.  
• Keep annotations short. No more than one paragraph.  

For examples of a  properly formatted APA annotation, visit this guide on APA annotated bibliographies .  

In comparison to the sample annotated bibliography MLA, the APA sample formats its page elements and references differently.

Students and researchers who type their research notes can save time by using an annotated bibliography template in MLA format while reviewing and analyzing sources. By adding the relevant information into a pre-formatted template, you’ll create a resource that helps you when you begin writing your paper in addition to saving time by completing your references and summaries alongside your research.

Students who prefer to take notes by hand can employ a modified version of this approach, with an additional step required to transfer your handwritten and formatted references from your notebook to populate your reference page.

Bibliography Template for MLA

To create an annotated bibliography MLA template, copy the following details into the program in which you will take notes or hand write it on the top margin of a page in your notebook. For each source, use this template to guide you as you identify the necessary details and insert them into your notes:

• Author (Last name, First name).
• Title of source.
• Title of the container ,
• Other contributors (names and roles),
• Publication Date,
• Location of the source (such as URL or page range).
• Summary or Analysis.

The MLA 9 model for MLA works cited entries offers a single format for all source type, and a great deal of flexibility to include the information most relevant to your topic and omit that which isn’t.

Hopefully our visual annotated bibliography example in MLA above has helped. If you still have lingering questions, visit the MLA Style Center online ( linked here ). Also, here’s a guide if you’re looking for more on the related topic of MLA in-text & parenthetical citations .

Bibliography Template for APA

Students and researchers who are still asking themselves how to piece together an annotated bibliography, or still questioning what is an annotated bibliography, could probably benefit from a template, similar to the one above. This one, however, is for those of you who are tasked with creating an annotated bibliography in the style created by the American Psychological Association.

The tricky thing about this specific style though, is that every reference is styled differently. Books, websites, journal articles, newspaper articles, and many others each have their own reference structure.

For most sources though, you should look for the following, basic information:

• Type of source
• Author (last name, first name)
• Title of source/article/web page, etc.
• Title of where source was found (e.g., database name, website name, etc.)
• Other contributors (names and roles)
• Location of the source (such as URL, DOI, or page range)
• Summary or Analysis

We understand it can get tricky, and it’s very different from the Modern Language Association’s structure for references. Take a moment to either use the other handy guides on EasyBib.com or use our automatic generator to form your references in just a few clicks. Our tools help take the pain away from having to rack your brain to form references properly. Capitals, lowercase letters, italics, quotation marks, punctuation in the appropriate places, it can all be quite overwhelming. Do yourself a favor, and use the EasyBib automatic citation generator.

Even though there are a lot of different variations, here’s a commonly used structure for sources:

Author’s Last Name, First initial, Middle initial. (Year the source was published). Title of the source . Retrieved from (insert the website address here)

Underneath the reference, include your summary or analysis paragraph.

Hopefully, this page helped answer all of your “What is an annotated bibliography?” questions. If you’re seeking out an annotated bibliography generator, follow the steps above the annotated bibliography examples.

If you are creating a bibliography in MLA format, the EasyBib MLA bibliography generator can help save you time formatting your citations and annotations correctly. You can create entries for websites, books, videos, databases, dictionary articles, and many other types of sources.

In addition to forming the citations, you can also enter your annotation text to produce the complete entry for each source. The process for this is simple. You can follow along below to practice creating one:

• First, select your source type from among the 50+ available options. For this example, we will use the acting career of Keanu Reeves as our research topic and use the movie Point Break from 1991 as our first source. To cite this film, you would select the option for “Film/Online Video.” As you follow along, pick the option that is suitable for your source if you are using a different example.
• Enter the title of your source or, if you are citing a website, you may enter the URL. (Now would be a great time to peek at how to cite websites in MLA ). After you enter the title or URL for your reference, the EasyBib citation tool will scan for titles that match it and provide you with a list of results. Select “Cite this” next to the listing that matches your source.
• You will see a citation form. This gives you the option to add additional relevant or necessary information. For our sample topic, we will specifically cite Keanu Reeves as the performer and Kathryn Bigelow as the director.
• After entering any additional details, you have the option to expand your entry and include an annotation. To do so, select “Add annotation” at the bottom of the page, and a text box will open up.

Then, type your summary or analysis into the text box. If you took notes during the research stage using the format of your paper, this might be as simple as copying and pasting your already written summary or critique. Once you have entered all of the necessary information, select “Create citation” to generate the complete entry. You can then copy and paste this into your MLA bibliography.

Here’s what it’ll look like:

Point Break . Directed by Kathryn Bigelow, performance by Keanu Reeves, 20th Century Fox, 1991.

Reeves’ role as rookie FBI Agent Johnny Utah in Point Break marks the turning point in his Hollywood film career. While he’d risen to fame due to the success of the Bill and Ted franchise, his status today as an action star began when Point Break provided him with the material to establish himself as capable of portraying more than the lovable but unserious characters of his previous starring roles. In a parallel arc, director Kathryn Bigelow’s career also sees a shift beginning with Point Break , establishing her within the traditional action genre as a serious director capable of creating high-action and visually memorable films. While Point Break leaves plenty to be desired in terms of dialogue, it afforded Bigelow and Reeves the opportunities to showcase themselves and their talent in new ways that still echo in their work today.

An annotated bibliography is a list containing complete information of sources, such as journals, books, and reports, cited in the text. In addition, it provides a brief description of each source in about 100–150 words. The annotation can explain the topics covered in the source or evaluate the source. The main objective of giving the annotation is to provide the reader the importance, accuracy, and value of the source.

An example of an annotated bibliography in APA style is given below.

Lim, L. (2014). Ideology, rationality and reproduction in education: A critical discourse analysis. Discourse: Studies in the Cultural Politics of Education, 35 (1), 61–76. https://doi:10.1080/01596306.2012.739467

Lim (2014) focuses on issues of power and ideology dominant in curricular discourses of rationality to study a discourse analysis of the goals of one of the most important curricula in the teaching of thinking. He proves that political and class commitments are reproduced in the forms of thinking that are valued in societies. Through his research, Lim asserts that such curricula engage in making our understanding of what thinking and rationality are. It must facilitate the social reproduction of a specific proportion of the middle class.

If you want to evaluate or provide a description of a source you are citing, you can create an annotated bibliography. Write your annotation in 100–150 words and add it below the source for which you are providing your annotation. Remember, your annotation should provide the reader the importance, accuracy, and value of the source. Below are the guidelines and rules to be followed while writing an annotated bibliography for APA style:

Order your reference entries in alphabetical order, similar to how you would order entries in the reference list.

If you want to add an annotation to an entry, add it as a fresh paragraph below the reference entry. The annotation is indented 0.5 inches from the left margin. However, the first line of the annotation is not indented.

To format the annotated bibliography, follow the recommendations given below:

Set the left, right, top, and bottom margins to 1 inch.

Give double-line spacing.

Title the page “Annotated Bibliography.” Set it in bold.

The title should be aligned to the center of the page.

As you format reference entries, left-align all references in the annotated bibliography section. If any entry runs over more than a line, indent the subsequent lines 0.5 inch from the left margin.

Arrange all reference entries alphabetically according to the surname of the authors.

Provide your annotations below the reference entry for which you want to give your annotation. Indent annotations 0.5 inches from the left margin.

What Is an Annotated Bibliography?

• An Introduction to Punctuation
• Ph.D., Rhetoric and English, University of Georgia
• M.A., Modern English and American Literature, University of Leicester
• B.A., English, State University of New York

An annotated bibliography is a list of sources (usually articles and books) on a selected topic accompanied by a brief summary and evaluation of each source.

Examples and Observations

An annotated bibliography is really a series of notes about other articles. The purpose of an annotated bibliography is to present an overview of the published literature on a topic by summarizing the key articles. Olin and Uris libraries ([Cornell University] 2008) offers practical advice on preparing an annotated bibliography.

An annotated bibliography is a list of citations to books, articles, and documents. Each citation is followed by a brief (usually about 150 words) descriptive and evaluative paragraph, the annotations. The purpose of the annotation is to inform the reader of the relevance, accuracy and quality of the sources cited. The annotation is a concise and succinct analysis.

• "Although preparing an annotated bibliography is time-consuming, it can be very helpful during the drafting or revising stage. If you realize, for instance, that you need more information on a particular topic, your annotations can often direct you to the most useful source."

Basic Features of an Annotated Bibliography

• "Regardless of the format you choose for your annotated bibliography, your audience will expect to see clear citation formats like MLA, APA, or Chicago . If your readers decide to look up a source, they need to be able to find it easily, so providing them with complete and accurate information in a familiar, readable format is critical. "Your description of sources' content will vary in terms of depth, depending on your purpose and your readers. For some projects, you might merely indicate the topic of a source, while for others you might thoroughly summarize your sources, describing their conclusions or even their methodologies in detail. Comments per source in annotated bibliographies can range in length from a sentence to a paragraph or two. "Annotated bibliographies often go beyond summary to tell the reader something important about their central question or topic, and how each source connects to it. You might help the reader understand the significance of studies in your field generally, or you might evaluate their significance with regard to the question you are researching."

Characteristics of an Excellent Annotated Bibliography

• "Annotated bibliographies are written alphabetically, by surname of author and should have a consistent format or structure. The annotation is usually quite short, just one or two sentences and comes immediately after the bibliographical source. The actual style and length may vary slightly from one discipline to another or even between institutions, so you should always check for any specific style or format to be used and be consistent in your writing and presentation." "What differentiates an excellent annotated bibliography from an average one? While the criteria may vary between courses, institutions, and subject and disciplinary areas, there are some common points that you should be aware of: a) Relevance to topic. . . . b) Currency of literature. . . . c) Breadth of scholarship. . . . d) Variety of sources. . . . e) Quality of individual annotation. . . ."

​​Excerpts From Collaborative Writing: An Annotated Bibliography

• In this introduction to the special issue, Beard and Rymer claim that collaborative writing is coming to be viewed as a way of constructing knowledge. They provide a brief overview for the many contexts of collaborative writing discussed in the special issue. Bruffee has observed an increase in the use of collaborative learning strategies in both the classroom and the workplace, and he attributes this increase to the growing discussion of social constructionist theory. In the writing classroom, collaborative learning can take the form of peer editing and reviewing, as well as group projects. The key to success for collaborative learning in any classroom is semi-autonomy for the students. While the teacher serves as the director of group processes, there must be some degree of autonomy for the students so that they may take some responsibility for the direction of their own learning.

Frequently asked questions

What types of sources should i use in an annotated bibliography.

Any credible sources on your topic can be included in an annotated bibliography . The exact sources you cover will vary depending on the assignment, but you should usually focus on collecting journal articles and scholarly books . When in doubt, utilize the CRAAP test !

Frequently asked questions: Citing sources

A scientific citation style is a system of source citation that is used in scientific disciplines. Some commonly used scientific citation styles are:

• Chicago author-date , CSE , and Harvard , used across various sciences
• ACS , used in chemistry
• AMA , NLM , and Vancouver , used in medicine and related disciplines
• AAA , APA , and ASA , commonly used in the social sciences

There are many different citation styles used across different academic disciplines, but they fall into three basic approaches to citation:

• Parenthetical citations : Including identifying details of the source in parentheses —usually the author’s last name and the publication date, plus a page number if available ( author-date ). The publication date is occasionally omitted ( author-page ).
• Numerical citations: Including a number in brackets or superscript, corresponding to an entry in your numbered reference list.
• Note citations: Including a full citation in a footnote or endnote , which is indicated in the text with a superscript number or symbol.

A source annotation in an annotated bibliography fulfills a similar purpose to an abstract : they’re both intended to summarize the approach and key points of a source.

However, an annotation may also evaluate the source , discussing the validity and effectiveness of its arguments. Even if your annotation is purely descriptive , you may have a different perspective on the source from the author and highlight different key points.

You should never just copy text from the abstract for your annotation, as doing so constitutes plagiarism .

Most academics agree that you shouldn’t cite Wikipedia as a source in your academic writing , and universities often have rules against doing so.

This is partly because of concerns about its reliability, and partly because it’s a tertiary source. Tertiary sources are things like encyclopedias and databases that collect information from other sources rather than presenting their own evidence or analysis. Usually, only primary and secondary sources are cited in academic papers.

A Wikipedia citation usually includes the title of the article, “Wikipedia” and/or “Wikimedia Foundation,” the date the article was last updated, and the URL.

In APA Style , you’ll give the URL of the current revision of the article so that you’re sure the reader accesses the same version as you.

There’s some disagreement about whether Wikipedia can be considered a reliable source . Because it can be edited by anyone, many people argue that it’s easy for misleading information to be added to an article without the reader knowing.

Others argue that because Wikipedia articles cite their sources , and because they are worked on by so many editors, misinformation is generally removed quickly.

However, most universities state that you shouldn’t cite Wikipedia in your writing.

Hanging indents are used in reference lists in various citation styles to allow the reader to easily distinguish between entries.

You should apply a hanging indent to your reference entries in APA , MLA , and Chicago style.

A hanging indent is used to indent all lines of a paragraph except the first.

When you create a hanging indent, the first line of the paragraph starts at the border. Each subsequent line is indented 0.5 inches (1.27 cm).

APA and MLA style both use parenthetical in-text citations to cite sources and include a full list of references at the end, but they differ in other ways:

• APA in-text citations include the author name, date, and page number (Taylor, 2018, p. 23), while MLA in-text citations include only the author name and page number (Taylor 23).
• The APA reference list is titled “References,” while MLA’s version is called “ Works Cited .”
• The reference entries differ in terms of formatting and order of information.
• APA requires a title page , while MLA requires a header instead.

A parenthetical citation in Chicago author-date style includes the author’s last name, the publication date, and, if applicable, the relevant page number or page range in parentheses . Include a comma after the year, but not after the author’s name.

For example: (Swan 2003, 6)

To automatically generate accurate Chicago references, you can use Scribbr’s free Chicago reference generator .

APA Style distinguishes between parenthetical and narrative citations.

In parenthetical citations , you include all relevant source information in parentheses at the end of the sentence or clause: “Parts of the human body reflect the principles of tensegrity (Levin, 2002).”

In narrative citations , you include the author’s name in the text itself, followed by the publication date in parentheses: “Levin (2002) argues that parts of the human body reflect the principles of tensegrity.”

In a parenthetical citation in MLA style , include the author’s last name and the relevant page number or range in parentheses .

For example: (Eliot 21)

A parenthetical citation gives credit in parentheses to a source that you’re quoting or paraphrasing . It provides relevant information such as the author’s name, the publication date, and the page number(s) cited.

How you use parenthetical citations will depend on your chosen citation style . It will also depend on the type of source you are citing and the number of authors.

APA does not permit the use of ibid. This is because APA in-text citations are parenthetical and there’s no need to shorten them further.

Ibid. may be used in Chicago footnotes or endnotes .

Write “Ibid.” alone when you are citing the same page number and source as the previous citation.

When you are citing the same source, but a different page number, use ibid. followed by a comma and the relevant page number(s). For example:

• Ibid., 40–42.

Only use ibid . if you are directing the reader to a previous full citation of a source .

Ibid. only refers to the previous citation. Therefore, you should only use ibid. directly after a citation that you want to repeat.

Ibid. is an abbreviation of the Latin “ibidem,” meaning “in the same place.” Ibid. is used in citations to direct the reader to the previous source.

Signal phrases can be used in various ways and can be placed at the beginning, middle, or end of a sentence.

To use signal phrases effectively, include:

• The name of the scholar(s) or study you’re referencing
• An attributive tag such as “according to” or “argues that”
• The quote or idea you want to include

Different citation styles require you to use specific verb tenses when using signal phrases.

• APA Style requires you to use the past or present perfect tense when using signal phrases.
• MLA and Chicago requires you to use the present tense when using signal phrases.

Signal phrases allow you to give credit for an idea or quote to its author or originator. This helps you to:

• Establish the credentials of your sources
• Display your depth of reading and understanding of the field
• Position your own work in relation to other scholars
• Avoid plagiarism

A signal phrase is a group of words that ascribes a quote or idea to an outside source.

Signal phrases distinguish the cited idea or argument from your own writing and introduce important information including the source of the material that you are quoting , paraphrasing , or summarizing . For example:

“ Cognitive psychologist Steven Pinker (1994) insists that humans possess an innate faculty for comprehending grammar.”

If you’re quoting from a text that paraphrases or summarizes other sources and cites them in parentheses , APA and Chicago both recommend retaining the citations as part of the quote. However, MLA recommends omitting citations within a quote:

• APA: Smith states that “the literature on this topic (Jones, 2015; Sill, 2019; Paulson, 2020) shows no clear consensus” (Smith, 2019, p. 4).
• MLA: Smith states that “the literature on this topic shows no clear consensus” (Smith, 2019, p. 4).

Footnote or endnote numbers that appear within quoted text should be omitted in all styles.

If you want to cite an indirect source (one you’ve only seen quoted in another source), either locate the original source or use the phrase “as cited in” in your citation.

In scientific subjects, the information itself is more important than how it was expressed, so quoting should generally be kept to a minimum. In the arts and humanities, however, well-chosen quotes are often essential to a good paper.

In social sciences, it varies. If your research is mainly quantitative , you won’t include many quotes, but if it’s more qualitative , you may need to quote from the data you collected .

As a general guideline, quotes should take up no more than 5–10% of your paper. If in doubt, check with your instructor or supervisor how much quoting is appropriate in your field.

To present information from other sources in academic writing , it’s best to paraphrase in most cases. This shows that you’ve understood the ideas you’re discussing and incorporates them into your text smoothly.

It’s appropriate to quote when:

• Changing the phrasing would distort the meaning of the original text
• You want to discuss the author’s language choices (e.g., in literary analysis )
• You’re presenting a precise definition
• You’re looking in depth at a specific claim

To paraphrase effectively, don’t just take the original sentence and swap out some of the words for synonyms. Instead, try:

• Reformulating the sentence (e.g., change active to passive , or start from a different point)
• Combining information from multiple sentences into one
• Leaving out information from the original that isn’t relevant to your point
• Using synonyms where they don’t distort the meaning

The main point is to ensure you don’t just copy the structure of the original text, but instead reformulate the idea in your own words.

“ Et al. ” is an abbreviation of the Latin term “et alia,” which means “and others.” It’s used in source citations to save space when there are too many authors to name them all.

Guidelines for using “et al.” differ depending on the citation style you’re following:

To insert endnotes in Microsoft Word, follow the steps below:

• Click on the spot in the text where you want the endnote to show up.
• In the “References” tab at the top, select “Insert Endnote.”
• Type whatever text you want into the endnote.

If you need to change the type of notes used in a Word document from footnotes to endnotes , or the other way around, follow these steps:

• Open the “References” tab, and click the arrow in the bottom-right corner of the “Footnotes” section.
• In the pop-up window, click on “Convert…”
• Choose the option you need, and click “OK.”

To insert a footnote automatically in a Word document:

• Click on the point in the text where the footnote should appear
• Select the “References” tab at the top and then click on “Insert Footnote”
• Type the text you want into the footnote that appears at the bottom of the page

Footnotes are notes indicated in your text with numbers and placed at the bottom of the page. They’re used to provide:

• Citations (e.g., in Chicago notes and bibliography )
• Additional information that would disrupt the flow of the main text

Be sparing in your use of footnotes (other than citation footnotes), and consider whether the information you’re adding is relevant for the reader.

Footnotes appear at the bottom of the page they refer to. This is convenient for the reader but may cause your text to look cluttered if there are a lot of footnotes.

Endnotes appear all together at the end of the whole text. This may be less convenient for the reader but reduces clutter.

Both footnotes and endnotes are used in the same way: to cite sources or add extra information. You should usually choose one or the other to use in your text, not both.

An in-text citation is an acknowledgement you include in your text whenever you quote or paraphrase a source. It usually gives the author’s last name, the year of publication, and the page number of the relevant text. In-text citations allow the reader to look up the full source information in your reference list and see your sources for themselves.

If you are reusing content or data you used in a previous assignment, make sure to cite yourself. You can cite yourself just as you would cite any other source: simply follow the directions for that source type in the citation style you are using.

Keep in mind that reusing your previous work can be considered self-plagiarism , so make sure you ask your professor or consult your university’s handbook before doing so.

A credible source should pass the CRAAP test  and follow these guidelines:

• The information should be up to date and current.
• The author and publication should be a trusted authority on the subject you are researching.
• The sources the author cited should be easy to find, clear, and unbiased.
• For a web source, the URL and layout should signify that it is trustworthy.

Peer review is a process of evaluating submissions to an academic journal. Utilizing rigorous criteria, a panel of reviewers in the same subject area decide whether to accept each submission for publication. For this reason, academic journals are often considered among the most credible sources you can use in a research project– provided that the journal itself is trustworthy and well-regarded.

Academic dishonesty can be intentional or unintentional, ranging from something as simple as claiming to have read something you didn’t to copying your neighbor’s answers on an exam.

You can commit academic dishonesty with the best of intentions, such as helping a friend cheat on a paper. Severe academic dishonesty can include buying a pre-written essay or the answers to a multiple-choice test, or falsifying a medical emergency to avoid taking a final exam.

Academic dishonesty refers to deceitful or misleading behavior in an academic setting. Academic dishonesty can occur intentionally or unintentionally, and varies in severity.

It can encompass paying for a pre-written essay, cheating on an exam, or committing plagiarism . It can also include helping others cheat, copying a friend’s homework answers, or even pretending to be sick to miss an exam.

Academic dishonesty doesn’t just occur in a classroom setting, but also in research and other academic-adjacent fields.

To apply a hanging indent to your reference list or Works Cited list in Word or Google Docs, follow the steps below.

Microsoft Word:

• Highlight the whole list and right click to open the Paragraph options.
• Under Indentation > Special , choose Hanging from the dropdown menu.
• Set the indent to 0.5 inches or 1.27cm.

Google Docs:

• Highlight the whole list and click on Format >  Align and indent >  Indentation options .
• Under  Special indent , choose Hanging from the dropdown menu.

When the hanging indent is applied, for each reference, every line except the first is indented. This helps the reader see where one entry ends and the next begins.

For a published interview (whether in video , audio, or print form ), you should always include a citation , just as you would for any other source.

For an interview you conducted yourself , formally or informally, you often don’t need a citation and can just refer to it in the text or in a footnote , since the reader won’t be able to look them up anyway. MLA , however, still recommends including citations for your own interviews.

The main elements included in a newspaper interview citation across APA , MLA , and Chicago style are the names of the interviewer and interviewee, the interview title, the publication date, the name of the newspaper, and a URL (for online sources).

The information is presented differently in different citation styles. One key difference is that APA advises listing the interviewer in the author position, while MLA and Chicago advise listing the interviewee first.

The elements included in a newspaper article citation across APA , MLA , and Chicago style are the author name, the article title, the publication date, the newspaper name, and the URL if the article was accessed online .

In APA and MLA, the page numbers of the article appear in place of the URL if the article was accessed in print. No page numbers are used in Chicago newspaper citations.

Untitled sources (e.g. some images ) are usually cited using a short descriptive text in place of the title. In APA Style , this description appears in brackets: [Chair of stained oak]. In MLA and Chicago styles, no brackets are used: Chair of stained oak.

For social media posts, which are usually untitled, quote the initial words of the post in place of the title: the first 160 characters in Chicago , or the first 20 words in APA . E.g. Biden, J. [@JoeBiden]. “The American Rescue Plan means a $7,000 check for a single mom of four. It means more support to safely.”

MLA recommends quoting the full post for something short like a tweet, and just describing the post if it’s longer.

The main elements included in image citations across APA , MLA , and Chicago style are the name of the image’s creator, the image title, the year (or more precise date) of publication, and details of the container in which the image was found (e.g. a museum, book , website ).

In APA and Chicago style, it’s standard to also include a description of the image’s format (e.g. “Photograph” or “Oil on canvas”). This sort of information may be included in MLA too, but is not mandatory.

The main elements included in a lecture citation across APA , MLA , and Chicago style are the name of the speaker, the lecture title, the date it took place, the course or event it was part of, and the institution it took place at.

For transcripts or recordings of lectures/speeches, other details like the URL, the name of the book or website , and the length of the recording may be included instead of information about the event and institution.

The main elements included in a YouTube video citation across APA , MLA , and Chicago style are the name of the author/uploader, the title of the video, the publication date, and the URL.

The format in which this information appears is different for each style.

All styles also recommend using timestamps as a locator in the in-text citation or Chicago footnote .

Each annotation in an annotated bibliography is usually between 50 and 200 words long. Longer annotations may be divided into paragraphs .

The content of the annotation varies according to your assignment. An annotation can be descriptive, meaning it just describes the source objectively; evaluative, meaning it assesses its usefulness; or reflective, meaning it explains how the source will be used in your own research .

An annotated bibliography is an assignment where you collect sources on a specific topic and write an annotation for each source. An annotation is a short text that describes and sometimes evaluates the source.

The elements included in journal article citations across APA , MLA , and Chicago style are the name(s) of the author(s), the title of the article, the year of publication, the name of the journal, the volume and issue numbers, the page range of the article, and, when accessed online, the DOI or URL.

In MLA and Chicago style, you also include the specific month or season of publication alongside the year, when this information is available.

In APA , MLA , and Chicago style citations for sources that don’t list a specific author (e.g. many websites ), you can usually list the organization responsible for the source as the author.

If the organization is the same as the website or publisher, you shouldn’t repeat it twice in your reference:

• In APA and Chicago, omit the website or publisher name later in the reference.
• In MLA, omit the author element at the start of the reference, and cite the source title instead.

If there’s no appropriate organization to list as author, you will usually have to begin the citation and reference entry with the title of the source instead.

The main elements included in website citations across APA , MLA , and Chicago style are the author, the date of publication, the page title, the website name, and the URL. The information is presented differently in each style.

When you want to cite a specific passage in a source without page numbers (e.g. an e-book or website ), all the main citation styles recommend using an alternate locator in your in-text citation . You might use a heading or chapter number, e.g. (Smith, 2016, ch. 1)

In APA Style , you can count the paragraph numbers in a text to identify a location by paragraph number. MLA and Chicago recommend that you only use paragraph numbers if they’re explicitly marked in the text.

For audiovisual sources (e.g. videos ), all styles recommend using a timestamp to show a specific point in the video when relevant.

The abbreviation “ et al. ” (Latin for “and others”) is used to shorten citations of sources with multiple authors.

“Et al.” is used in APA in-text citations of sources with 3+ authors, e.g. (Smith et al., 2019). It is not used in APA reference entries .

Use “et al.” for 3+ authors in MLA in-text citations and Works Cited entries.

Use “et al.” for 4+ authors in a Chicago in-text citation , and for 10+ authors in a Chicago bibliography entry.

Check if your university or course guidelines specify which citation style to use. If the choice is left up to you, consider which style is most commonly used in your field.

• APA Style is the most popular citation style, widely used in the social and behavioral sciences.
• MLA style is the second most popular, used mainly in the humanities.
• Chicago notes and bibliography style is also popular in the humanities, especially history.
• Chicago author-date style tends to be used in the sciences.

Other more specialized styles exist for certain fields, such as Bluebook and OSCOLA for law.

The most important thing is to choose one style and use it consistently throughout your text.

The main elements included in all book citations across APA , MLA , and Chicago style are the author, the title, the year of publication, and the name of the publisher. A page number is also included in in-text citations to highlight the specific passage cited.

In Chicago style and in the 6th edition of APA Style , the location of the publisher is also included, e.g. London: Penguin.

A block quote is a long quote formatted as a separate “block” of text. Instead of using quotation marks , you place the quote on a new line, and indent the entire quote to mark it apart from your own words.

The rules for when to apply block quote formatting depend on the citation style:

• APA block quotes are 40 words or longer.
• MLA block quotes are more than 4 lines of prose or 3 lines of poetry.
• Chicago block quotes are longer than 100 words.

In academic writing , there are three main situations where quoting is the best choice:

• To analyze the author’s language (e.g., in a literary analysis essay )
• To give evidence from primary sources
• To accurately present a precise definition or argument

Don’t overuse quotes; your own voice should be dominant. If you just want to provide information from a source, it’s usually better to paraphrase or summarize .

Every time you quote a source , you must include a correctly formatted in-text citation . This looks slightly different depending on the citation style .

For example, a direct quote in APA is cited like this: “This is a quote” (Streefkerk, 2020, p. 5).

Every in-text citation should also correspond to a full reference at the end of your paper.

A quote is an exact copy of someone else’s words, usually enclosed in quotation marks and credited to the original author or speaker.

The DOI is usually clearly visible when you open a journal article on an academic database. It is often listed near the publication date, and includes “doi.org” or “DOI:”. If the database has a “cite this article” button, this should also produce a citation with the DOI included.

If you can’t find the DOI, you can search on Crossref using information like the author, the article title, and the journal name.

A DOI is a unique identifier for a digital document. DOIs are important in academic citation because they are more permanent than URLs, ensuring that your reader can reliably locate the source.

Journal articles and ebooks can often be found on multiple different websites and databases. The URL of the page where an article is hosted can be changed or removed over time, but a DOI is linked to the specific document and never changes.

When a book’s chapters are written by different authors, you should cite the specific chapter you are referring to.

When all the chapters are written by the same author (or group of authors), you should usually cite the entire book, but some styles include exceptions to this.

• In APA Style , single-author books should always be cited as a whole, even if you only quote or paraphrase from one chapter.
• In MLA Style , if a single-author book is a collection of stand-alone works (e.g. short stories ), you should cite the individual work.
• In Chicago Style , you may choose to cite a single chapter of a single-author book if you feel it is more appropriate than citing the whole book.

Articles in newspapers and magazines can be primary or secondary depending on the focus of your research.

In historical studies, old articles are used as primary sources that give direct evidence about the time period. In social and communication studies, articles are used as primary sources to analyze language and social relations (for example, by conducting content analysis or discourse analysis ).

If you are not analyzing the article itself, but only using it for background information or facts about your topic, then the article is a secondary source.

A fictional movie is usually a primary source. A documentary can be either primary or secondary depending on the context.

If you are directly analyzing some aspect of the movie itself – for example, the cinematography, narrative techniques, or social context – the movie is a primary source.

If you use the movie for background information or analysis about your topic – for example, to learn about a historical event or a scientific discovery – the movie is a secondary source.

Whether it’s primary or secondary, always properly cite the movie in the citation style you are using. Learn how to create an MLA movie citation or an APA movie citation .

To determine if a source is primary or secondary, ask yourself:

• Was the source created by someone directly involved in the events you’re studying (primary), or by another researcher (secondary)?
• Does the source provide original information (primary), or does it summarize information from other sources (secondary)?
• Are you directly analyzing the source itself (primary), or only using it for background information (secondary)?

Some types of source are nearly always primary: works of art and literature, raw statistical data, official documents and records, and personal communications (e.g. letters, interviews ). If you use one of these in your research, it is probably a primary source.

Primary sources are often considered the most credible in terms of providing evidence for your argument, as they give you direct evidence of what you are researching. However, it’s up to you to ensure the information they provide is reliable and accurate.

Always make sure to properly cite your sources to avoid plagiarism .

Common examples of secondary sources include academic books, journal articles , reviews, essays , and textbooks.

Anything that summarizes, evaluates or interprets primary sources can be a secondary source. If a source gives you an overview of background information or presents another researcher’s ideas on your topic, it is probably a secondary source.

Common examples of primary sources include interview transcripts , photographs, novels, paintings, films, historical documents, and official statistics.

Anything you directly analyze or use as first-hand evidence can be a primary source, including qualitative or quantitative data that you collected yourself.
