Annotation Fundamentals

How to start annotating , how to annotate digital texts, how to annotate a textbook, how to annotate a scholarly article or book, how to annotate literature, how to annotate images, videos, and performances, additional resources for teachers.

Writing in your books can make you smarter. Or, at least (according to education experts), annotation–an umbrella term for underlining, highlighting, circling, and, most importantly, leaving comments in the margins–helps students to remember and comprehend what they read. Annotation is like a conversation between reader and text. Proper annotation allows students to record their own opinions and reactions, which can serve as the inspiration for research questions and theses. So, whether you're reading a novel, poem, news article, or science textbook, taking notes along the way can give you an advantage in preparing for tests or writing essays. This guide contains resources that explain the benefits of annotating texts, provide annotation tools, and suggest approaches for diverse kinds of texts; the last section includes lesson plans and exercises for teachers.

Why annotate? As the resources below explain, annotation allows students to emphasize connections to material covered elsewhere in the text (or in other texts), material covered previously in the course, or material covered in lectures and discussion. In other words, proper annotation is an organizing tool and a time saver. The links in this section will introduce you to the theory, practice, and purpose of annotation. 

How to Mark a Book, by Mortimer Adler

This famous, charming essay lays out the case for marking up books, and provides practical suggestions at the end including underlining, highlighting, circling key words, using vertical lines to mark shifts in tone/subject, numbering points in an argument, and keeping track of questions that occur to you as you read.

Here, a sixth grade teacher demonstrates the strategies she uses for getting her students to annotate with sticky notes. This resource includes a link to the teacher's free Annotation Bookmark (via Teachers Pay Teachers).

Digital texts can present a special challenge when it comes to annotation; emerging research suggests that many students struggle to critically read and retain information from digital texts. However, proper annotation can solve the problem. This section contains links to the most highly-utilized platforms for electronic annotation.

Evernote is one of the two big players in the "digital annotation apps" game. In addition to allowing users to annotate digital documents, the service (for a fee) allows users to group multiple formats (PDF, webpages, scanned hand-written notes) into separate notebooks, create voice recordings, and sync across all sorts of devices. 

OneNote is Evernote's main competitor. Reviews suggest that OneNote allows for more freedom for digital note-taking than Evernote, but that it is slightly more awkward to import and annotate a PDF, especially on certain platforms. However, OneNote's free version is slightly more feature-filled, and OneNote allows you to link your notes to time stamps on an audio recording.

Diigo is a basic browser extension that allows a user to annotate webpages. Diigo also offers a Screenshot app that allows for direct saving to Google Drive.

Narrative Essay

How to write an annotation.

One of the greatest challenges students face is adjusting to college reading expectations.  Unlike high school, students in college are expected to read more “academic” type of materials in less time and usually recall the information as soon as the next class.

The problem is many students spend hours reading and have no idea what they just read.  Their eyes are moving across the page, but their mind is somewhere else. The end result is wasted time, energy, and frustration…and having to read the text again.

Although students are taught  how to read  at an early age, many are not taught  how to actively engage  with written text or other media. Annotation is a tool to help you learn how to actively engage with a text or other media.

View the following video about how to annotate a text.

Annotating a text or other media (e.g. a video, image, etc.) is as much about you as it is the text you are annotating. What are YOUR responses to the author’s writing, claims and ideas? What are YOU thinking as you consider the work? Ask questions, challenge, think!

When we annotate an author’s work, our minds should encounter the mind of the author, openly and freely. If you met the author at a party, what would you like to tell to them; what would you like to ask them? What do you think they would say in response to your comments? You can be critical of the text, but you do not have to be. If you are annotating properly, you often begin to get ideas that have little or even nothing to do with the topic you are annotating. That’s fine: it’s all about generating insights and ideas of your own. Any good insight is worth keeping because it may make for a good essay or research paper later on.

The Secret is in the Pen

One of the ways proficient readers read is with a pen in hand. They know their purpose is to keep their attention on the material by:

• Predicting  what the material will be about
• Questioning  the material to further understanding
• Determining  what’s important
• Identifying  key vocabulary
• Summarizing  the material in their own words, and
• Monitoring  their comprehension (understanding) during and after engaging with the material

The same applies for mindfully viewing a film, video, image or other media.

Annotating a Text

Review the video, “How to Annotate a Text.”  Pay attention to both how to make annotations and what types of thoughts and ideas may be part of your annotations as you actively read a written text.

Example Assignment Format: Annotating a Written Text

For the annotation of reading assignments in this class, you will cite and comment on a minimum of FIVE (5) phrases, sentences or passages from notes you take on the selected readings.

Here is an example format for an assignment to annotate a written text:

Example Assignment Format: Annotating Media

In addition to annotating written text, at times you will have assignments to annotate media (e.g., videos, images or other media). For the annotation of media assignments in this class, you will cite and comment on a minimum of THREE (3) statements, facts, examples, research or any combination of those from the notes you take about selected media.

Annotating Texts

What is annotation.

Annotation can be:

• A systematic summary of the text that you create within the document
• A key tool for close reading that helps you uncover patterns, notice important words, and identify main points
• An active learning strategy that improves comprehension and retention of information

Why annotate?

• Isolate and organize important material
• Identify key concepts
• Monitor your learning as you read
• Make exam prep effective and streamlined
• Can be more efficient than creating a separate set of reading notes

How do you annotate?

Summarize key points in your own words .

• Use headers and words in bold to guide you
• Look for main ideas, arguments, and points of evidence
• Notice how the text organizes itself. Chronological order? Idea trees? Etc.

Circle key concepts and phrases

• What words would it be helpful to look-up at the end?
• What terms show up in lecture? When are different words used for similar concepts? Why?

Write brief comments and questions in the margins

• Be as specific or broad as you would like—use these questions to activate your thinking about the content
• See our handout on reading comprehension tips for some examples

Use abbreviations and symbols

• Try ? when you have a question or something you need to explore further
• Try ! When something is interesting, a connection, or otherwise worthy of note
• Try * For anything that you might use as an example or evidence when you use this information.
• Ask yourself what other system of symbols would make sense to you.

Highlight/underline

• Highlight or underline, but mindfully. Check out our resource on strategic highlighting for tips on when and how to highlight.

Use comment and highlight features built into pdfs, online/digital textbooks, or other apps and browser add-ons

• Are you using a pdf? Explore its highlight, edit, and comment functions to support your annotations
• Some browsers have add-ons or extensions that allow you to annotate web pages or web-based documents
• Does your digital or online textbook come with an annotation feature?
• Can your digital text be imported into a note-taking tool like OneNote, EverNote, or Google Keep? If so, you might be able to annotate texts in those apps

What are the most important takeaways?

• Annotation is about increasing your engagement with a text
• Increased engagement, where you think about and process the material then expand on your learning, is how you achieve mastery in a subject
• As you annotate a text, ask yourself: how would I explain this to a friend?
• Put things in your own words and draw connections to what you know and wonder

The table below demonstrates this process using a geography textbook excerpt (Press 2004):

A common concern about annotating texts: It takes time!

Yes, it can, but that time isn’t lost—it’s invested.

Spending the time to annotate on the front end does two important things:

• It saves you time later when you’re studying. Your annotated notes will help speed up exam prep, because you can review critical concepts quickly and efficiently.
• It increases the likelihood that you will retain the information after the course is completed. This is especially important when you are supplying the building blocks of your mind and future career.

One last tip: Try separating the reading and annotating processes! Quickly read through a section of the text first, then go back and annotate.

Sample Papers

This page contains sample papers formatted in seventh edition APA Style. The sample papers show the format that authors should use to submit a manuscript for publication in a professional journal and that students should use to submit a paper to an instructor for a course assignment. You can download the Word files to use as templates and edit them as needed for the purposes of your own papers.

Most guidelines in the Publication Manual apply to both professional manuscripts and student papers. However, there are specific guidelines for professional papers versus student papers, including professional and student title page formats. All authors should check with the person or entity to whom they are submitting their paper (e.g., publisher or instructor) for guidelines that are different from or in addition to those specified by APA Style.

Sample student paper templates by paper type

These sample papers demonstrate APA Style formatting standards for different student paper types. Students may write the same types of papers as professional authors (e.g., quantitative studies, literature reviews) or other types of papers for course assignments (e.g., reaction or response papers, discussion posts), dissertations, and theses.

APA does not set formal requirements for the nature or contents of an APA Style student paper. Students should follow the guidelines and requirements of their instructor, department, and/or institution when writing papers. For instance, an abstract and keywords are not required for APA Style student papers, although an instructor may request them in student papers that are longer or more complex. Specific questions about a paper being written for a course assignment should be directed to the instructor or institution assigning the paper.

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 their 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 they may have a different style they want 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 they want 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 they expect 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!

• How to Write an Annotation

One of the greatest challenges students face is adjusting to college reading expectations.  Unlike high school, students in college are expected to read more “academic” type of materials in less time and usually recall the information as soon as the next class.

The problem is many students spend hours reading and have no idea what they just read.  Their eyes are moving across the page, but their mind is somewhere else. The end result is wasted time, energy, and frustration…and having to read the text again.

Although students are taught  how to read  at an early age, many are not taught  how to actively engage  with written text or other media. Annotation is a tool to help you learn how to actively engage with a text or other media.

View the following video about how to annotate a text.

Annotating a text or other media (e.g. a video, image, etc.) is as much about you as it is the text you are annotating. What are YOUR responses to the author’s writing, claims and ideas? What are YOU thinking as you consider the work? Ask questions, challenge, think!

When we annotate an author’s work, our minds should encounter the mind of the author, openly and freely. If you met the author at a party, what would you like to tell to them; what would you like to ask them? What do you think they would say in response to your comments? You can be critical of the text, but you do not have to be. If you are annotating properly, you often begin to get ideas that have little or even nothing to do with the topic you are annotating. That’s fine: it’s all about generating insights and ideas of your own. Any good insight is worth keeping because it may make for a good essay or research paper later on.

The Secret is in the Pen

One of the ways proficient readers read is with a pen in hand. They know their purpose is to keep their attention on the material by:

• Predicting  what the material will be about
• Questioning  the material to further understanding
• Determining  what’s important
• Identifying  key vocabulary
• Summarizing  the material in their own words, and
• Monitoring  their comprehension (understanding) during and after engaging with the material

The same applies for mindfully viewing a film, video, image or other media.

Annotating a Text

Review the video, “How to Annotate a Text.”  Pay attention to both how to make annotations and what types of thoughts and ideas may be part of your annotations as you actively read a written text.

Example Assignment Format: Annotating a Written Text

For the annotation of reading assignments in this class, you will cite and comment on a minimum of FIVE (5) phrases, sentences or passages from notes you take on the selected readings.

Here is an example format for an assignment to annotate a written text:

Example Assignment Format: Annotating Media

In addition to annotating written text, at times you will have assignments to annotate media (e.g., videos, images or other media). For the annotation of media assignments in this class, you will cite and comment on a minimum of THREE (3) statements, facts, examples, research or any combination of those from the notes you take about selected media.

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

Below you will find sample annotations from annotated bibliographies, each with a different research project. Remember that the annotations you include in your own bibliography should reflect your research project and/or the guidelines of your assignment.

As mentioned elsewhere in this resource, depending on the purpose of your bibliography, some annotations may summarize, some may assess or evaluate a source, and some may reflect on the source’s possible uses for the project at hand. Some annotations may address all three of these steps. Consider the purpose of your annotated bibliography and/or your instructor’s directions when deciding how much information to include in your annotations.

Please keep in mind that all your text, including the write-up beneath the citation, must be indented so that the author's last name is the only text that is flush left.

Sample MLA Annotation

Lamott, Anne. Bird by Bird: Some Instructions on Writing and Life . Anchor Books, 1995.

Lamott's book offers honest advice on the nature of a writing life, complete with its insecurities and failures. Taking a humorous approach to the realities of being a writer, the chapters in Lamott's book are wry and anecdotal and offer advice on everything from plot development to jealousy, from perfectionism to struggling with one's own internal critic.

In the process, Lamott includes writing exercises designed to be both productive and fun. Lamott offers sane advice for those struggling with the anxieties of writing, but her main project seems to be offering the reader a reality check regarding writing, publishing, and struggling with one's own imperfect humanity in the process. Rather than a practical handbook to producing and/or publishing, this text is indispensable because of its honest perspective, its down-to-earth humor, and its encouraging approach.

Chapters in this text could easily be included in the curriculum for a writing class. Several of the chapters in Part 1 address the writing process and would serve to generate discussion on students' own drafting and revising processes. Some of the writing exercises would also be appropriate for generating classroom writing exercises. Students should find Lamott's style both engaging and enjoyable.

In the sample annotation above, the writer includes three paragraphs: a summary, an evaluation of the text, and a reflection on its applicability to his/her own research, respectively.

For information on formatting MLA citations, see our MLA 9th Edition (2021) Formatting and Style Guide .

Sample APA Annotation

Ehrenreich, B. (2001). Nickel and dimed: On (not) getting by in America . Henry Holt and Company.

In this book of nonfiction based on the journalist's experiential research, Ehrenreich attempts to ascertain whether it is currently possible for an individual to live on a minimum-wage in America. Taking jobs as a waitress, a maid in a cleaning service, and a Walmart sales employee, the author summarizes and reflects on her work, her relationships with fellow workers, and her financial struggles in each situation.

An experienced journalist, Ehrenreich is aware of the limitations of her experiment and the ethical implications of her experiential research tactics and reflects on these issues in the text. The author is forthcoming about her methods and supplements her experiences with scholarly research on her places of employment, the economy, and the rising cost of living in America. Ehrenreich’s project is timely, descriptive, and well-researched.

The annotation above both summarizes and assesses the book in the citation. The first paragraph provides a brief summary of the author's project in the book, covering the main points of the work. The second paragraph points out the project’s strengths and evaluates its methods and presentation. This particular annotation does not reflect on the source’s potential importance or usefulness for this person’s own research.

For information on formatting APA citations, see our APA Formatting and Style Guide .

Sample Chicago Manual of Style Annotation

Davidson, Hilda Ellis. Roles of the Northern Goddess . London: Routledge, 1998.

Davidson's book provides a thorough examination of the major roles filled by the numerous pagan goddesses of Northern Europe in everyday life, including their roles in hunting, agriculture, domestic arts like weaving, the household, and death. The author discusses relevant archaeological evidence, patterns of symbol and ritual, and previous research. The book includes a number of black and white photographs of relevant artifacts.

This annotation includes only one paragraph, a summary of the book. It provides a concise description of the project and the book's project and its major features.

Sample Annotations

This example uses MLA format for an online magazine.  It both summarizes and assesses the article in the annotation. First it provides a brief summary of the article, covering the main points of the work. Then it notes its limitation.

Dickenson’s article gives a history of the oil spill created by the explosion on the Deepwater Horizon rig and efforts to downplay the disaster by BP and the Obama administration. The author concedes the role of the Bush administration in allowing oil companies to control the Mineral Management Service (MMS), but he blames the Obama administration for not correcting this problem and not taking responsibility for the cleanup immediately after the spill. BP drilled the well using cost-cutting methods instead of safer construction plans and without a strategy for sealing a leak. BP has a history of safety violations and should not have been trusted with the cleanup. Officials from NOAA warned of the extent of the spill immediately, but both BP and the President downplayed the damage. Dickenson concludes that the President’s decision not to act immediately after the spill will affect the Gulf region for many years. This article provides readers with details about obvious problems with the Deepwater Horizon well before the explosion and explains how a quicker response by the President could have prevented some of the damage to the fragile Gulf ecosystem. Although the article was written only a month after the disaster, it shows early reactions to the spill and cleanup attempts. 

Dolgin begins his essay by describing research into RNA vaccines.  In 2012, researcher Andy Geall used RNA nucleotides to vaccinate rats against a respiratory virus, and in 2013 he developed a vaccination against an avian flu, but his vaccine was not used. The advent of COVID-19 speeded up research into the development of RNA vaccines, and now major pharmaceutical companies are researching using them to prevent diseases like rabies, malaria, and HIV. Once the genome sequence of a virus in known, developing a vaccine is quicker when using RNA technology. One issue with RNA vaccines is that they must be stored at cold temperatures, although two companies claim to have solved this problem. Although RNA vaccines require two injections at this time, researchers are looking for easier ways to deliver them; one example is using patches placed on the skin to deliver the vaccine slowly, which may reduce side effects. Research is continuing in hopes of creating vaccines for diseases like muscular dystrophy and cystic fibrosis, although many believe that this research will slow when COVID-19 is no longer in the news. Dolgin’s essay is documented with footnotes citing major medical publications like Lancet and Vaccine and published in Nature, a respected journal that includes peer-reviewed research. Dolgin is a science journalist with a PhD in evolutionary genetics who contributes articles to journals like Scientific American and The Scientist. Although this essay does include scientific terms, it is easy to understand because it is written for a general audience.

How to Write an Annotated Bibliography

Writing annotations.

• Introduction
• New RefWorks
• Formatting Citations
• Sample Annotated Bibliographies

An annotation is a brief note following each citation listed on an annotated bibliography.  The goal is to briefly summarize the source and/or explain why it is important for a topic.  They are typically a single concise paragraph, but might be longer if you are summarizing and evaluating.

Annotations can be written in a variety of different ways and it’s important to consider the style you are going to use.  Are you simply summarizing the sources, or evaluating them?  How does the source influence your understanding of the topic?  You can follow any style you want if you are writing for your own personal research process, but consult with your professor if this is an assignment for a class.

Annotation Styles

• Combined Informative/Evaluative Style - This style is recommended by the library as it combines all the styles to provide a more complete view of a source.  The annotation should explain the value of the source for the overall research topic by providing a summary combined with an analysis of the source.  

Aluedse, O. (2006). Bullying in schools: A form of child abuse in schools.  Educational Research Quarterly ,  30 (1), 37.

The author classifies bullying in schools as a “form of child abuse,” and goes well beyond the notion that schoolyard bullying is “just child’s play.” The article provides an in-depth definition of bullying, and explores the likelihood that school-aged bullies may also experience difficult lives as adults. The author discusses the modern prevalence of bullying in school systems, the effects of bullying, intervention strategies, and provides an extensive list of resources and references.

Statistics included provide an alarming realization that bullying is prevalent not only in the United States, but also worldwide. According to the author, “American schools harbor approximately 2.1 million bullies and 2.7 million victims.” The author references the National Association of School Psychologists and quotes, “Thus, one in seven children is a bully or a target of bullying.” A major point of emphasis centers around what has always been considered a “normal part of growing up” versus the levels of actual abuse reached in today’s society.

The author concludes with a section that addresses intervention strategies for school administrators, teachers, counselors, and school staff. The concept of school staff helping build students’ “social competence” is showcased as a prevalent means of preventing and reducing this growing social menace. Overall, the article is worthwhile for anyone interested in the subject matter, and provides a wealth of resources for researching this topic of growing concern.

(Renfrow & Teuton, 2008)

• Informative Style -  Similar to an abstract, this style focuses on the summarizing the source.  The annotation should identify the hypothesis, results, and conclusions presented by the source.

Plester, B., Wood, C, & Bell, V. (2008). Txt msg n school literacy: Does texting and knowledge of text abbreviations adversely affect children's literacy attainment? Literacy , 42(3), 137-144.

Reports on two studies that investigated the relationship between children's texting behavior, their knowledge of text abbreviations, and their school attainment in written language skills. In Study One, 11 to 12 year-old children reported their texting behavior and translated a standard English sentence into a text message and vice versa. In Study Two, children's performance on writing measures were examined more specifically, spelling proficiency was also assessed, and KS2 Writing scores were obtained. Positive correlations between spelling ability and performance on the translation exercise were found, and group-based comparisons based on the children's writing scores also showed that good writing attainment was associated with greater use of texting abbreviations (textisms), although the direction of this association is not clear. Overall, these findings suggest that children's knowledge of textisms is not associated with poor written language outcomes for children in this age range. 

(Beach et al., 2009)

• Evaluative Style - This style analyzes and critically evaluates the source.  The annotation should comment on the source's the strengths, weaknesses, and how it relates to the overall research topic.

Amott, T. (1993). Caught in the Crisis: Women in the U.S. Economy Today . New York: Monthly Review Press.

A very readable (140 pp) economic analysis and information book which I am currently considering as a required collateral assignment in Economics 201. Among its many strengths is a lucid connection of "The Crisis at Home" with the broader, macroeconomic crisis of the U.S. working class (which various other authors have described as the shrinking middle class or the crisis of de-industrialization).

(Papadantonakis, 1996)

• Indicative Style - This style of annotation identifies the main theme and lists the significant topics included in the source.  Usually no specific details are given beyond the topic list . 

Example: 

Gambell, T.J., & Hunter, D. M. (1999). Rethinking gender differences in literacy. Canadian Journal of Education , 24(1) 1-16.

Five explanations are offered for recently assessed gender differences in the literacy achievement of male and female students in Canada and other countries. The explanations revolve around evaluative bias, home socialization, role and societal expectations, male psychology, and equity policy.

What Is an Annotated Bibliography - and Why Write it at the Beginning of Your Research?

An annotated bibliography is a bibliography that includes a summary and/or evaluation of each of the sources. Each citation is followed by a brief note – or annotation – that describes various aspects of the source such as a summary, an evaluation of the content, and applicability to your topic.

Why should an annotated bibliography come at the BEGINNING of your research assignment?   A researcher can use an annotated bibliography to do a critical summary of each source: its importance, its strengths and weaknesses, and the ways in which the source will fit into your research. When doing an annotated bibliography, researchers analyze and don't summarize.

How Can a Good Annotated Bibliography Help Me With My EE?

The process is not just a matter of listing possible sources. It also requires you to think critically. Consider your sources in terms of:

• what has already been written about their chosen topic and
• how your own research will fit into this.

As you examine each source, you will need to identify the issues and different perspectives of others. This will help you to develop a reasoned argument.

• allow you to keep track of your reading
• encourage you to think critically about the sources you are using in relation to your research area
• allow you, quite early on in the process, to become aware of possible concerns about using certain sources
• help you determine whether a source is of use to you in your research
• help you to justify your use of particular sources, both to your supervisor and to the IB examiner who will be reading your essay
• help you with the planning of your research, and ultimately save you time
• enable you to develop critical-thinking skills in selecting and evaluating source material.

What Should an Annotation Include?

• the bibliographic information
• the annotations (a concise summary of the source).

The annotations will vary in length depending on whether you are writing a summary of the source or analyzing it.

A summary should include:         

• a concise summary of the content and theme(s) of the source
• a comment on the authority of the author
• a comment on the purpose of the source
• a comment on how this source might be useful.         

What Do Sample Annotations Look Like?

The following are examples of annotations in several IB disciplines.

Social and cultural anthropology

What Should the Annotation Include?

This video tutorial from Champlain College Library explains what an annotated bibliography is and what each annotation should include.  The short paragraphs describing each source on the list should summarize the source, evaluate it, and discuss how it would fit into your topic.

Champlain College Library, prod. What's an Annotated Bibliography? YouTube.       Champlain College Lib., 2 Feb. 2012. Web. 17 Apr. 2016.       <https://youtu.be/RZoIXuRyTgI>. 

How Do I Write an Annotation?

The Cornell University Library has defined an annotated bibliography as: a list of citations to books, articles, and documents. Each citation is followed by a brief  (usually about 150 words)  descriptive and evaluative paragraph. This means you are creating a paragraph that others may read to get a general idea of what your sources are about. The hardest part is being concise with your information. Annotations take practice but once you get the hang of it they are easy. Here are the steps to follow:   Step 1: Talk about the author. (1 sentence) Is this a professor? Maybe this is a professional in the field? Or is this person a hobbyist? Tell the audience about the author in the first part of the annotation. Step 2: Explain what the article is about. (1-3 sentences) Tell the audience what is in the article. This is the most difficult part of the annotation because it requires you to be very succinct. Don’t rewrite the article; just write the base facts and important notes about the article here. Step 3: Explain how this article illuminates your bibliography topic. (1-2 sentences) What about this article makes it relevant to your topic? Why did you select it? What pertinent bit of information makes this article stand out among the others? Step 4: Compare or contrast this work with another you have cited. (1-2 sentences) How does this specific article relate to another article in your annotated bibliography? Do they agree or not? Why not? What makes them unique?

Frequently asked questions

How do i write an annotation for a source.

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 .

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 .

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 !

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.
