A Quick Guide to Referencing | Cite Your Sources Correctly

Referencing means acknowledging the sources you have used in your writing. Including references helps you support your claims and ensures that you avoid plagiarism .

There are many referencing styles, but they usually consist of two things:

  • A citation wherever you refer to a source in your text.
  • A reference list or bibliography at the end listing full details of all your sources.

The most common method of referencing in UK universities is Harvard style , which uses author-date citations in the text. Our free Harvard Reference Generator automatically creates accurate references in this style.

Referencing styles, citing your sources with in-text citations, creating your reference list or bibliography, harvard referencing examples, frequently asked questions about referencing.

Each referencing style has different rules for presenting source information. For in-text citations, some use footnotes or endnotes , while others include the author’s surname and date of publication in brackets in the text.

The reference list or bibliography is presented differently in each style, with different rules for things like capitalisation, italics, and quotation marks in references.

Your university will usually tell you which referencing style to use; they may even have their own unique style. Always follow your university’s guidelines, and ask your tutor if you are unsure. The most common styles are summarised below.

Harvard referencing, the most commonly used style at UK universities, uses author–date in-text citations corresponding to an alphabetical bibliography or reference list at the end.

Vancouver referencing, used in biomedicine and other sciences, uses reference numbers in the text corresponding to a numbered reference list at the end.

APA referencing, used in the social and behavioural sciences, uses author–date in-text citations corresponding to an alphabetical reference list at the end.

MHRA referencing, used in the humanities, uses footnotes in the text with source information, in addition to an alphabetised bibliography at the end.

OSCOLA referencing, used in law, uses footnotes in the text with source information, and an alphabetical bibliography at the end in longer texts.

In-text citations should be used whenever you quote, paraphrase, or refer to information from a source (e.g. a book, article, image, website, or video).

Quoting and paraphrasing

Quoting is when you directly copy some text from a source and enclose it in quotation marks to indicate that it is not your own writing.

Paraphrasing is when you rephrase the original source into your own words. In this case, you don’t use quotation marks, but you still need to include a citation.

In most referencing styles, page numbers are included when you’re quoting or paraphrasing a particular passage. If you are referring to the text as a whole, no page number is needed.

In-text citations

In-text citations are quick references to your sources. In Harvard referencing, you use the author’s surname and the date of publication in brackets.

Up to three authors are included in a Harvard in-text citation. If the source has more than three authors, include the first author followed by ‘ et al. ‘

The point of these citations is to direct your reader to the alphabetised reference list, where you give full information about each source. For example, to find the source cited above, the reader would look under ‘J’ in your reference list to find the title and publication details of the source.

Placement of in-text citations

In-text citations should be placed directly after the quotation or information they refer to, usually before a comma or full stop. If a sentence is supported by multiple sources, you can combine them in one set of brackets, separated by a semicolon.

If you mention the author’s name in the text already, you don’t include it in the citation, and you can place the citation immediately after the name.

  • Another researcher warns that the results of this method are ‘inconsistent’ (Singh, 2018, p. 13) .
  • Previous research has frequently illustrated the pitfalls of this method (Singh, 2018; Jones, 2016) .
  • Singh (2018, p. 13) warns that the results of this method are ‘inconsistent’.

The terms ‘bibliography’ and ‘reference list’ are sometimes used interchangeably. Both refer to a list that contains full information on all the sources cited in your text. Sometimes ‘bibliography’ is used to mean a more extensive list, also containing sources that you consulted but did not cite in the text.

A reference list or bibliography is usually mandatory, since in-text citations typically don’t provide full source information. For styles that already include full source information in footnotes (e.g. OSCOLA and Chicago Style ), the bibliography is optional, although your university may still require you to include one.

Format of the reference list

Reference lists are usually alphabetised by authors’ last names. Each entry in the list appears on a new line, and a hanging indent is applied if an entry extends onto multiple lines.

Harvard reference list example

Different source information is included for different source types. Each style provides detailed guidelines for exactly what information should be included and how it should be presented.

Below are some examples of reference list entries for common source types in Harvard style.

  • Chapter of a book
  • Journal article

Your university should tell you which referencing style to follow. If you’re unsure, check with a supervisor. Commonly used styles include:

  • Harvard referencing , the most commonly used style in UK universities.
  • MHRA , used in humanities subjects.
  • APA , used in the social sciences.
  • Vancouver , used in biomedicine.
  • OSCOLA , used in law.

Your university may have its own referencing style guide.

If you are allowed to choose which style to follow, we recommend Harvard referencing, as it is a straightforward and widely used style.

References should be included in your text whenever you use words, ideas, or information from a source. A source can be anything from a book or journal article to a website or YouTube video.

If you don’t acknowledge your sources, you can get in trouble for plagiarism .

To avoid plagiarism , always include a reference when you use words, ideas or information from a source. This shows that you are not trying to pass the work of others off as your own.

You must also properly quote or paraphrase the source. If you’re not sure whether you’ve done this correctly, you can use the Scribbr Plagiarism Checker to find and correct any mistakes.

Harvard referencing uses an author–date system. Sources are cited by the author’s last name and the publication year in brackets. Each Harvard in-text citation corresponds to an entry in the alphabetised reference list at the end of the paper.

Vancouver referencing uses a numerical system. Sources are cited by a number in parentheses or superscript. Each number corresponds to a full reference at the end of the paper.

How to Cite Sources

Here is a complete list for how to cite sources. Most of these guides present citation guidance and examples in MLA, APA, and Chicago.

If you’re looking for general information on MLA or APA citations , the EasyBib Writing Center was designed for you! It has articles on what’s needed in an MLA in-text citation , how to format an APA paper, what an MLA annotated bibliography is, making an MLA works cited page, and much more!

MLA Format Citation Examples

The Modern Language Association created the MLA Style, currently in its 9th edition, to provide researchers with guidelines for writing and documenting scholarly borrowings.  Most often used in the humanities, MLA style (or MLA format ) has been adopted and used by numerous other disciplines, in multiple parts of the world.

MLA provides standard rules to follow so that most research papers are formatted in a similar manner. This makes it easier for readers to comprehend the information. The MLA in-text citation guidelines, MLA works cited standards, and MLA annotated bibliography instructions provide scholars with the information they need to properly cite sources in their research papers, articles, and assignments.

  • Book Chapter
  • Conference Paper
  • Documentary
  • Encyclopedia
  • Google Images
  • Kindle Book
  • Memorial Inscription
  • Museum Exhibit
  • Painting or Artwork
  • PowerPoint Presentation
  • Sheet Music
  • Thesis or Dissertation
  • YouTube Video

APA Format Citation Examples

The American Psychological Association created the APA citation style in 1929 as a way to help psychologists, anthropologists, and even business managers establish one common way to cite sources and present content.

APA is used when citing sources for academic articles such as journals, and is intended to help readers better comprehend content, and to avoid language bias wherever possible. The APA style (or APA format ) is now in its 7th edition, and provides citation style guides for virtually any type of resource.

Chicago Style Citation Examples

The Chicago/Turabian style of citing sources is generally used when citing sources for humanities papers, and is best known for its requirement that writers place bibliographic citations at the bottom of a page (in Chicago-format footnotes ) or at the end of a paper (endnotes).

The Turabian and Chicago citation styles are almost identical, but the Turabian style is geared towards student published papers such as theses and dissertations, while the Chicago style provides guidelines for all types of publications. This is why you’ll commonly see Chicago style and Turabian style presented together. The Chicago Manual of Style is currently in its 17th edition, and Turabian’s A Manual for Writers of Research Papers, Theses, and Dissertations is in its 8th edition.

6 Interesting Citation Facts

The world of citations may seem cut and dry, but there’s more to them than just specific capitalization rules, MLA in-text citations , and other formatting specifications. Citations have been helping researches document their sources for hundreds of years, and are a great way to learn more about a particular subject area.

Ever wonder what sets all the different styles apart, or how they came to be in the first place? Read on for some interesting facts about citations!

1. There are Over 7,000 Different Citation Styles

You may be familiar with MLA and APA citation styles, but there are actually thousands of citation styles used for all different academic disciplines all across the world. Deciding which one to use can be difficult, so be sure to ask you instructor which one you should be using for your next paper.

2. Some Citation Styles are Named After People

While a majority of citation styles are named for the specific organizations that publish them (i.e. APA is published by the American Psychological Association, and MLA format is named for the Modern Language Association), some are actually named after individuals. The most well-known example of this is perhaps Turabian style, named for Kate L. Turabian, an American educator and writer. She developed this style as a condensed version of the Chicago Manual of Style in order to present a more concise set of rules to students.

3. There are Some Really Specific and Uniquely Named Citation Styles

How specific can citation styles get? The answer is very. For example, the “Flavour and Fragrance Journal” style is based on a bimonthly, peer-reviewed scientific journal published since 1985 by John Wiley & Sons. It publishes original research articles, reviews and special reports on all aspects of flavor and fragrance. Another example is “Nordic Pulp and Paper Research,” a style used by an international scientific magazine covering science and technology for the areas of wood or bio-mass constituents.

4. More citations were created on  EasyBib.com  in the first quarter of 2018 than there are people in California.

The US Census Bureau estimates that approximately 39.5 million people live in the state of California. Meanwhile, about 43 million citations were made on EasyBib from January to March of 2018. That’s a lot of citations.

5. “Citations” is a Word With a Long History

The word “citations” can be traced back literally thousands of years to the Latin word “citare” meaning “to summon, urge, call; put in sudden motion, call forward; rouse, excite.” The word then took on its more modern meaning and relevance to writing papers in the 1600s, where it became known as the “act of citing or quoting a passage from a book, etc.”

6. Citation Styles are Always Changing

The concept of citations always stays the same. It is a means of preventing plagiarism and demonstrating where you relied on outside sources. The specific style rules, however, can and do change regularly. For example, in 2018 alone, 46 new citation styles were introduced , and 106 updates were made to exiting styles. At EasyBib, we are always on the lookout for ways to improve our styles and opportunities to add new ones to our list.

Why Citations Matter

Here are the ways accurate citations can help your students achieve academic success, and how you can answer the dreaded question, “why should I cite my sources?”

They Give Credit to the Right People

Citing their sources makes sure that the reader can differentiate the student’s original thoughts from those of other researchers. Not only does this make sure that the sources they use receive proper credit for their work, it ensures that the student receives deserved recognition for their unique contributions to the topic. Whether the student is citing in MLA format , APA format , or any other style, citations serve as a natural way to place a student’s work in the broader context of the subject area, and serve as an easy way to gauge their commitment to the project.

They Provide Hard Evidence of Ideas

Having many citations from a wide variety of sources related to their idea means that the student is working on a well-researched and respected subject. Citing sources that back up their claim creates room for fact-checking and further research . And, if they can cite a few sources that have the converse opinion or idea, and then demonstrate to the reader why they believe that that viewpoint is wrong by again citing credible sources, the student is well on their way to winning over the reader and cementing their point of view.

They Promote Originality and Prevent Plagiarism

The point of research projects is not to regurgitate information that can already be found elsewhere. We have Google for that! What the student’s project should aim to do is promote an original idea or a spin on an existing idea, and use reliable sources to promote that idea. Copying or directly referencing a source without proper citation can lead to not only a poor grade, but accusations of academic dishonesty. By citing their sources regularly and accurately, students can easily avoid the trap of plagiarism , and promote further research on their topic.

They Create Better Researchers

By researching sources to back up and promote their ideas, students are becoming better researchers without even knowing it! Each time a new source is read or researched, the student is becoming more engaged with the project and is developing a deeper understanding of the subject area. Proper citations demonstrate a breadth of the student’s reading and dedication to the project itself. By creating citations, students are compelled to make connections between their sources and discern research patterns. Each time they complete this process, they are helping themselves become better researchers and writers overall.

When is the Right Time to Start Making Citations?

Make in-text/parenthetical citations as you need them.

As you are writing your paper, be sure to include references within the text that correspond with references in a works cited or bibliography. These are usually called in-text citations or parenthetical citations in MLA and APA formats. The most effective time to complete these is directly after you have made your reference to another source. For instance, after writing the line from Charles Dickens’ A Tale of Two Cities : “It was the best of times, it was the worst of times…,” you would include a citation like this (depending on your chosen citation style):

(Dickens 11).

This signals to the reader that you have referenced an outside source. What’s great about this system is that the in-text citations serve as a natural list for all of the citations you have made in your paper, which will make completing the works cited page a whole lot easier. After you are done writing, all that will be left for you to do is scan your paper for these references, and then build a works cited page that includes a citation for each one.

2. Understand the General Formatting Rules of Your Citation Style Before You Start Writing

While reading up on paper formatting may not sound exciting, being aware of how your paper should look early on in the paper writing process is super important. Citation styles can dictate more than just the appearance of the citations themselves, but rather can impact the layout of your paper as a whole, with specific guidelines concerning margin width, title treatment, and even font size and spacing. Knowing how to organize your paper before you start writing will ensure that you do not receive a low grade for something as trivial as forgetting a hanging indent.

Don’t know where to start? Here’s a formatting guide on APA format .

3. Double-check All of Your Outside Sources for Relevance and Trustworthiness First

Collecting outside sources that support your research and specific topic is a critical step in writing an effective paper. But before you run to the library and grab the first 20 books you can lay your hands on, keep in mind that selecting a source to include in your paper should not be taken lightly. Before you proceed with using it to backup your ideas, run a quick Internet search for it and see if other scholars in your field have written about it as well. Check to see if there are book reviews about it or peer accolades. If you spot something that seems off to you, you may want to consider leaving it out of your work. Doing this before your start making citations can save you a ton of time in the long run.

Finished with your paper? It may be time to run it through a grammar and plagiarism checker , like the one offered by EasyBib Plus. If you’re just looking to brush up on the basics, our grammar guides  are ready anytime you are.

How to Write an Academic Essay with References and Citations

#scribendiinc

Written by  Scribendi

If you're wondering how to write an academic essay with references, look no further. In this article, we'll discuss how to use in-text citations and references, including how to cite a website, how to cite a book, and how to cite a Tweet, according to various style guides.

How to Cite a Website

You might need to cite sources when writing a paper that references other sources. For example, when writing an essay, you may use information from other works, such as books, articles, or websites. You must then inform readers where this information came from. Failure to do so, even accidentally, is plagiarism—passing off another person's work as your own.

You can avoid plagiarism and show readers where to find information by using citations and references. 

Citations tell readers where a piece of information came from. They take the form of footnotes, endnotes, or parenthetical elements, depending on your style guide. In-text citations are usually placed at the end of a sentence containing the relevant information. 

A reference list , bibliography, or works cited list at the end of a text provides additional details about these cited sources. This list includes enough publication information allowing readers to look up these sources themselves.

Referencing is important for more than simply avoiding plagiarism. Referring to a trustworthy source shows that the information is reliable. Referring to reliable information can also support your major points and back up your argument. 

Learning how to write an academic essay with references and how to use in-text citations will allow you to cite authors who have made similar arguments. This helps show that your argument is objective and not entirely based on personal biases.

How Do You Determine Which Style Guide to Use?

How to Write an Academic Essay with References

Often, a professor will assign a style guide. The purpose of a style guide is to provide writers with formatting instructions. If your professor has not assigned a style guide, they should still be able to recommend one. 

If you are entirely free to choose, pick one that aligns with your field (for example, APA is frequently used for scientific writing). 

Some of the most common style guides are as follows:

AP style for journalism

Chicago style for publishing

APA style for scholarly writing (commonly used in scientific fields)

MLA style for scholarly citations (commonly used in English literature fields)

Some journals have their own style guides, so if you plan to publish, check which guide your target journal uses. You can do this by locating your target journal's website and searching for author guidelines.

How Do You Pick Your Sources?

When learning how to write an academic essay with references, you must identify reliable sources that support your argument. 

As you read, think critically and evaluate sources for:

Objectivity

Keep detailed notes on the sources so that you can easily find them again, if needed.

Tip: Record these notes in the format of your style guide—your reference list will then be ready to go.

Many documentation styles pair in-text citations with a detailed list of sources, called references in APA and works cited in MLA, that provides enough information for readers to find the sources themselves. This section of the tutorial includes guidelines for how to cite the most common types of sources. To learn how to cite others, consult Chapters 6 and 7 of the Publication Manual of the American Psychological Association , 6th ed. or the MLA Handbook for Writers of Research Papers , 8th ed.

General Format for References (APA) / Works Cited (MLA)

  • Begin the list of sources on a separate numbered page at the end of the document.
  • Provide a title at the top of the page, “References” for APA or “Works Cited” for MLA, with no special formatting: bolding, underlining, quotation marks, larger font size, etc.
  • List all sources used in the document in alphabetical order.
  • Use a hanging indent so that only the first line of each entry lines up at the left margin; if an entry is more than one line long, all subsequent lines should be indented 0.5 inches.
  • Double space the entire list with no extra space between sources.

Rule to Remember

Any source cited in text must be included in the list of sources, and sources in the list of sources must be cited in text.

This tutorial includes only the most commonly cited kinds of sources. To learn how to cite less commonly seen works, consult the MLA Handbook for Writers of Research Papers , 6th ed. by Joseph Gribaldi (New York: MLA, 2003) or the Publication Manual of the American Psychological Association , 5th ed.

How to Properly List Sources in My Essay in the MLA Format

Modern Language Association style is commonly used for structuring papers related to English and the humanities. The seventh edition of the "MLA Handbook for Writers of Research Papers" provides guidelines on how to cite sources within your essay and how to list these sources in your references. When using MLA style, your reference page is called a Works Cited page.

In-Text Citations

When you quote, summarize or paraphrase someone else’s work within your essay, you must provide in-text citation. This information clearly points your readers to the specific sources on your Works Cited page. The general MLA format for in-text citations is the author’s last name and the page number within parentheses at the end of the referencing sentence before the punctuation.

The page number refers to the specific page from the author's work where you found the information you are using within your essay. For example,

"Broadcast news influences the decision-making process" (Postman 51-63).

If the author’s name is included in the sentence, you only need to include the page number within the parenthetical reference. For example,

“According to Postman, broadcast news influences the decision-making process" (51-63).

Works Cited Page

In MLA format, a Works Cited page appears at the end of your paper, listing all the sources you used. On its own separate page, the words “Works Cited” are centered on the first line; they do not need quotation marks or any extra formatting. This page uses the same formatting as the rest of your paper, with 1-inch margins, a legible 12-point font and a header featuring your last name and page number. The entries are alphabetized by author’s last name. All your citations are double-spaced, with no extra space between entries. For any citation that is more than one line long, the second and subsequent lines are indented five spaces.

Works Cited Entries

In MLA format, each entry on your Works Cited page features the author’s name, the title, city of publication, publisher’s name, date of publication and medium, such as a book, website or interview. The general format for a single author book in MLA style is the author’s last name, a comma, the author’s first name and a period. Next type the title of the book, in italics and title case, followed by a period. Then write the city of publication, a colon, the publisher’s name, a comma, the year of publication and a period. Finally, list the medium and end with a period. For example:

Wood, James. How Fiction Works. New York: Farrar, 2008. Print.

Internet Sources

Unlike other styles, MLA does not require you to include the URL when listing an Internet source on your Works Cited page. You list the author’s last name, a comma, first name and a period. If no name is available, you start with the title. Then comes the title of the website in italics and title case, followed by a period. Next, list the publisher or sponsor of the site, if given, a comma, the year it was published and a period. Write the medium, which in this case is Web, a period, the date you accessed the information and end with a period. For example:

Linder, Douglas O. Famous Trials. Univ. of Missouri Kansas-City Law School, 2009. Web. 29 Apr. 2009.

How to Reference in an Essay (9 Strategies of Top Students)

Are you feeling overwhelmed by referencing?

When you’re first asked to do referencing in an essay it can be hard to get your head around it. If it’s been a while since you were first taught how to reference, it can be intimidating to ask again how to do it!

I have so many students who consistently lose marks just because they didn’t get referencing right! They’re either embarrassed to ask for extra help or too lazy to learn how to solve the issues.

So, here’s a post that will help you solve the issues on your own.

Already think you’re good at referencing? No worries. This post goes through some surprising and advanced strategies for anyone to improve no matter what level you are at!

In this post I’m going to show you exactly how to reference in an essay. I’ll explain why we do it and I’ll show you 9 actionable tips on getting referencing right that I’m sure you will not have heard anywhere else!

The post is split into three parts:

  • What is a Reference and What is a Citation?
  • Why Reference? (4 Things you Should Know)
  • How to Reference (9 Strategies of Top Students)

If you think you’ve already got a good understanding of the basics, you can jump to our 9 Advanced Strategies section.

Part 1: What is a Reference and What is a Citation?

What is a citation.

An in-text mention of your source. A citation is a short mention of the source you got the information from, usually in the middle or end of a sentence in the body of your paragraph. It is usually abbreviated so as not to distract the reader too much from your own writing. Here’s two examples of citations. The first is in APA format. The second is in MLA format:

  • APA: Archaeological records trace the original human being to equatorial Africa about 250,000–350,000 years ago (Schlebusch & Jakobsson, 2018) .
  • MLA: Archaeological records trace the original human being to equatorial Africa about 250,000–350,000 years ago (Schlebusch and Jakobsson 1) .

In APA format, you’ve got the authors and year of publication listed. In MLA format, you’ve got the authors and page number listed. If you keep reading, I’ll give some more tips on formatting further down in this article.

And a Reference is:

What is a Reference?

A reference is the full details of a source that you list at the end of the article. For every citation (see above) there needs to be a corresponding reference at the end of the essay showing more details about that source. The idea is that the reader can see the source in-text (i.e. they can look at the citation) and if they want more information they can jump to the end of the page and find out exactly how to go about finding the source.

Here’s how you would go about referencing the Schlebusch and Jakobsson source in a list at the end of the essay. Again, I will show you how to do it in APA and MLA formats:

  • APA: Schlebusch, C. & Jakobsson, M. (2018). Tales of Human Migration, Admixture, and Selection in Africa. Annual Review of Genomics and Human Genetics , 11 (33), 1–24.
  • MLA: Schlebusch, Carina and Mattias Jakobsson. “Tales of Human Migration, Admixture, and Selection in Africa.” Annual Review of Genomics and Human Genetics , vol. 11, no. 33, 2018, pp. 1–24.

In strategy 1 below I’ll show you the easiest and fool proof way to write these references perfectly every time.

One last quick note: sometimes we say ‘reference’ when we mean ‘citation’. That’s pretty normal. Just roll with the punches. It’s usually pretty easy to pick up on what our teacher means regardless of whether they use the word ‘reference’ or ‘citation’.

Part 2: Why Reference in an Essay? (4 Things you Should Know)

Referencing in an essay is important. By the time you start doing 200-level courses, you probably won’t pass the course unless you reference appropriately. So, the biggest answer to ‘why reference?’ is simple: Because you Have To!

Okay let’s be serious though … here’s the four top ‘real’ reasons to reference:

1. Referencing shows you Got an Expert’s Opinion

You can’t just write an essay on what you think you know. This is a huge mistake of beginning students. Instead this is what you need to do:

Top Tip: Essays at university are supposed to show off that you’ve learned new information by reading the opinions of experts.

Every time you place a citation in your paragraph, you’re showing that the information you’re presenting in that paragraph was provided to you by an expert. In other words, it means you consulted an expert’s opinion to build your knowledge.

If you have citations throughout the essay with links to a variety of different expert opinions, you’ll show your marker that you did actually genuinely look at what the experts said with an open mind and considered their ideas.

This will help you to grow your grades.

2. Referencing shows you read your Assigned Readings

Your teacher will most likely give you scholarly journal articles or book chapters to read for homework between classes. You might have even talked about those assigned readings in your seminars and tutorials.

Great! The assigned readings are very important to you.

You should definitely cite the assigned readings relevant to your essay topic in your evaluative essay (unless your teacher tells you not to). Why? I’ll explain below.

  • Firstly, the assigned readings were selected by your teacher because your teacher (you know, the person who’s going to mark your essay) believes they’re the best quality articles on the topic. Translation: your teacher gave you the best source you’re going to find. Make sure you use it!
  • Secondly, by citing the assigned readings you are showing your teacher that you have been paying attention throughout the course. You are showing your teacher that you have done your homework, read those assigned readings and paid attention to them. When my students submit an essay that has references to websites, blogs, wikis and magazines I get very frustrated. Why would you cite low quality non-expert sources like websites when I gave you the expert’s article!? Really, it frustrates me so, so much.

So, cite the assigned readings to show your teacher you read the scholarly articles your teacher gave to you. It’ll help you grow your marks.

3. Referencing deepens your Knowledge

Okay, so you understand that you need to use referencing to show you got experts’ opinions on the topic.

But there’s more to it than that. There’s actually a real benefit for your learning.

If you force yourself to cite two expert sources per paragraph, you’re actually forcing yourself to get two separate pieces of expert knowledge. This will deepen your knowledge!

So, don’t treat referencing like a vanity exercise to help you gain more marks. Actually view it as an opportunity to develop deeper understandings of the topic!

When you read expert sources, aim to pick up on some new gems of knowledge that you can discuss in your essays. Some things you should look out for when finding sources to reference:

  • Examples that link ideas to real life. Do the experts provide real-life examples that you can mention in your essay?
  • Facts and figures. Usually experts have conducted research on a topic and provide you with facts and figures from their research. Use those facts and figures to deepen your essay!
  • Short Quotes. Did your source say something in a really interesting, concise or surprising way? Great! You can quote that source in your essay .
  • New Perspectives. Your source might give you another perspective, angle or piece of information that you can add to your paragraph so that it’s a deep, detailed and interesting paragraph.

So, the reason we ask you to reference is at the end of the day because it’s good for you: it helps you learn!

4. Referencing backs up your Claims

You might think you already know a ton of information about the topic and be ready to share your mountains of knowledge with your teacher. Great!

So, should you still reference?

Yes. Definitely.

You need to show that you’re not the only person with your opinion. You need to ‘stand on the shoulders of giants.’ Show what other sources have said about your points to prove that experts agree with you.

You should be saying: this is my opinion and it’s based on facts, expert opinions and deep, close scrutiny of all the arguments that exist out there .

If you make a claim that no one else has made, your teacher is going to be like “Have you even been reading the evidence on this topic?” The answer, if there are no citations is likely: No. You haven’t.

Even if you totally disagree with the experts, you still need to say what their opinions are! You’ll need to say: “This is the experts’ opinions. And this is why I disagree.”

So, yes, you need to reference to back up every claim. Try to reference twice in every paragraph to achieve this.

Part 3: Strategies for How to Reference in an Essay (9 Strategies of Top Students)

Let’s get going with our top strategies for how to reference in an essay! These are strategies that you probably haven’t heard elsewhere. They work for everyone – from beginner to advanced! Let’s get started:

1. Print out your Reference Style Cheat Sheet

Referencing is hard and very specific. You need to know where to place your italics, where the commas go and whether to use an initial for full name for an author.

There are so many details to get right.

And here’s the bad news: The automated referencing apps and websites nearly always get it wrong! They tell you they can generate the citation for you. The fact of the matter is: they can’t!

Here’s the best way to get referencing right: Download a referencing cheat sheet and have it by your side while writing your essay.

Your assignment outline should tell you what type of referencing you should use. Different styles include: APA Style, MLA Style, Chicago Style, Harvard Style, Vancouver Style … and many more!

You need to find out which style you need to use and download your cheat sheet. You can jump onto google to find a cheat sheet by typing in the google bar:

Download a pdf version of the referencing style cheat sheet, print it out, and place it on your pinboard or by your side when writing your essay.

2. Only cite Experts

There are good and bad sources to cite in an essay.

You should only cite sources written, critiqued and edited by experts. This shows that you have got the skill of finding information that is authoritative. You haven’t just used information that any old person popped up on their blog. You haven’t just gotten information from your local newspaper. Instead, you got information from the person who is an absolute expert on the topic.

Here’s an infographic listing sources that you should and shouldn’t cite. Feel free to share this infographic on social media, with your teachers and your friends:

good and bad sources infographic

3. Always use Google Scholar

Always. Use. Google. Scholar.

Ten years ago students only had their online university search database to find articles. Those university databases suck. They rarely find the best quality sources and there’s always a big mix of completely irrelevant sources mixed in there.

Google Scholar is better at finding the sources you want. That’s because it looks through the whole article abstract and analyses it to see if it’s relevant to your search keywords. By contrast, most university search databases rely only on the titles of articles.

Use the power of the best quality search engine in the world to find scholarly sources .

Note: Google and Google Scholar are different search engines.

To use Google Scholar, go to: https://scholar.google.com

Then, search on google scholar using keywords. I’m going to search keywords for an essay on the topic: “What are the traits of a good nurse?”

how to reference in an essay

If you really like the idea of that first source, I recommend copying the title and trying your University online search database. Your university may give you free access.

4. Cite at least 50% sources you found on your Own Research

Okay, so I’ve told you that you should cite both assigned readings and readings you find from Google Scholar.

Here’s the ideal mix of assigned sources and sources that you found yourself: 50/50.

Your teacher will want to see that you can use both assigned readings and do your own additional research to write a top essay . This shows you’ve got great research skills but also pay attention to what is provided in class.

I recommend that you start with the assigned readings and try to get as much information out of them, then find your own additional sources beyond that using Google Scholar.

So, if your essay has 10 citations, a good mix is 5 assigned readings and 5 readings you found by yourself.

5. Cite Newer Sources

As a general rule, the newer the source the better .

The best rule of thumb that most teachers follow is that you should aim to mostly cite sources from the past 10 years . I usually accept sources from the past 15 years when marking essays.

However, sometimes you have a really great source that’s 20, 30 or 40 years old. You should only cite these sources if they’re what we call ‘seminal texts’. A seminal text is one that was written by an absolute giant in your field and revolutionized the subject.

Here’s some examples of seminal authors whose old articles you would be able to cite despite the fact that they’re old:

  • Education: Vygotsky, Friere, Piaget
  • Sociology: Weber, Marx, C. Wright Mills
  • Psychology: Freud, Rogers, Jung

Even if I cite seminal authors, I always aim for at least 80% of my sources to have been written in the past 10 years.

6. Reference twice per Paragraph

How much should you reference?

Here’s a good strategy: Provide two citations in every paragraph in the body of the essay.

It’s not compulsory to reference in the introduction and conclusion . However, in all the other paragraphs, aim for two citations.

Let’s go over the key strategies for achieving this:

  • These two citations should be to different sources, not the same sources twice;
  • Two citations per paragraph shows your points are backed up by not one, but two expert sources;
  • Place one citation in the first half of the paragraph and one in the second half. This will indicate to your marker that all the points in the whole paragraph are backed up by your citations.

This is a good rule of thumb for you when you’re not sure when and how often to reference. When you get more confident with your referencing, you can mix this up a little.

7. The sum total of your sources should be minimum 1 per 150 words

You can, of course, cite one source more than once throughout the essay. You might cite the same source in the second, fourth and fifth paragraphs. That’s okay.

Essay Writing Tip: Provide one unique citation in the reference list for every 150 words in the essay.

But, you don’t want your whole essay to be based on a narrow range of sources. You want your marker to see that you have consulted multiple sources to get a wide range of information on the topic. Your marker wants to know that you’ve seen a range of different opinions when coming to your conclusions.

When you get to the end of your essay, check to see how many sources are listed in the end-text reference list. A good rule of thumb is 1 source listed in the reference list per 150 words. Here’s how that breaks down by essay size:

  • 1500 word essay: 10 sources (or more) listed in the reference list
  • 2000 word essay: 13 sources (or more) listed in the reference list
  • 3000 word essay: 20 sources (or more) listed in the reference list
  • 5000 word essay: 33 sources (or more) listed in the reference list

8. Instantly improve your Reference List with these Three Tips

Here’s two things you can do to instantly improve your reference list. It takes less than 20 seconds and gives your reference list a strong professional finish:

a) Ensure the font size and style are the same

You will usually find that your whole reference list ends up being in different font sizes and styles. This is because you tend to copy and paste the titles and names in the citations from other sources. If you submit the reference list with font sizes and styles that are not the same as the rest of the essay, the piece looks really unprofessional.

So, quickly highlight the whole reference list and change its font to the same font size and style as the rest of your essay. The screencast at the end of Step 8 walks you through this if you need a hand!

b) List your sources in alphabetical order.

Nearly every referencing style insists that references be listed in alphabetical order. It’s a simple thing to do before submitting and makes the piece look far more professional.

If you’re using Microsoft Word, simply highlight your whole reference list and click the A>Z button in the toolbar. If you can’t see it, you need to be under the ‘home’ tab (circled below):

how to reference in an essay

You’ve probably never heard of a hanging indent. It’s a style where the second line of the reference list is indented further from the left-hand side of the page than the first line. It’s a strategy that’s usually used in reference lists provided in professional publications.

If you use the hanging indent, your reference list will look far more professional.

Here’s a quick video of me doing it for you:

9. Do one special edit especially for Referencing Style

The top students edit their essays three to five times spaced out over a week or more before submitting. One of those edits should be specifically for ensuring your reference list adheres to the referencing style that your teacher requires.

To do this, I recommend you get that cheat sheet printout that I mentioned in Step 1 and have it by your side while you read through the piece. Pay special attention to the use of commas, capital letters, brackets and page numbers for all citations. Also pay attention to the reference list: correct formatting of the reference list can be the difference between getting the top mark in the class and the fifth mark in the class. At the higher end of the marking range, things get competitive and formatting of the reference list counts.

A Quick Summary of the 9 Top Strategies…

How to reference in an essay

Follow the rules of your referencing style guide (and that cheat sheet I recommended!) and use the top 9 tips above to improve your referencing and get top marks. Not only will your referencing look more professional, you’ll probably increase the quality of the content of your piece as well when you follow these tips!

A Source's Role in Your Paper

When you begin to draft your paper, you will need to decide what role each of your sources will play in your argument. In other words, you will need to figure out what you're going to do with the source in your paper. As you consider what role each source will play in your paper, you should begin by thinking about the role that source played in your research process. How did the source shape your thinking about the topic when you encountered it? If a source provided you with context for a particular problem or issue, then it may well do the same thing for your reader. If a source provided you with evidence that supports your claim, then you will probably want to lay out that evidence to your reader and explain how it leads you to the position you've staked out in your paper. If a source made an argument that challenged your own argument and made you refine your thinking, then you'll likely want to introduce that source in your paper as a counterargument before explaining why you have concluded that your own argument is stronger. On the other hand, if a source offered evidence or ideas that complicated your own thinking and made you shift your argument, you should explain how the source has led you to your new position.

Some assignments will ask you to respond in a specific way to a source. For example, you might be asked to test a theory developed in one source by using a body of evidence found in another source. Or you might be asked to respond to a claim or assumption laid out in a particular source. Other assignments may specify the number of sources you should use, but will not include instructions on how you should use those sources.

Here are some common roles that sources can play in your argument:

  • Provide primary evidence : a source can serve as the main object of your analysis, or offer evidence that has not yet been analyzed by others.
  • Establish what’s at stake : a source can present or highlight a problem, question or issue that provides a “so what” for your essay.
  • Serve as a lens : a source can offer a theory or concept that gives you a framework or focus for analyzing your evidence and building your argument.
  • Provide key terms/concepts : a source offers a central concept or key term that you apply to your own argument.
  • Provide context : a source can offer background (historical, cultural, etc.) that readers need to understand the argument you’re making or the issue you’re analyzing.
  • Serve as a supporting expert : you want to offer a claim, and you cite a scholar or researcher who notices the same or similar idea, thereby supporting your claim.
  • Advance your argument : a source provides a new insight that helps establish a main supporting claim to your overall argument; your use of that source should usually agree with and extend the idea or insight, demonstrating its application to your own analysis.
  • Provide a complication or counterargument : a source introduces an idea or raises a question that presents a problem for your argument, or an objection to contend with; your response to that complication enriches and adds nuance to your discussion.
  • Create a critical conversation : one source offers an idea that another source can respond to, sometimes in a very direct way (i.e. critic A explicitly disagrees with critic B), or by providing a different angle on or approach to the question (i.e. source A offers a new way of thinking about an idea raised in source B, a different "take" on the issue).

Selecting appropriate information

Using boolean operators, cautions from ib on using online encyclopedias (such as wikipedia) and other similar information websites.

Hazard warning attention sign - Britannica ImageQuest

  • they tend to be general encyclopedias
  • very often the author is unknown
  • there is no guarantee that the content meets standards of academic rigor —it may not, for example, have been through a process of peer review
  • the content can be unstable , in that it can change at any time.

Your teachers and EE supervisor may choose to caution you against using free online encyclopedias and other similar information websites. A bibliography that only cites these for reference or an argument that is overly reliant on them will not demonstrate the necessary “range of sources” required by the assessment criteria for the extended essay. They may also not be relevant or appropriate for the research question being explored.

Many online encyclopedias are not scholarly sources; however, if used appropriately and critically they can offer a useful starting point when undertaking research. 

If using free online encyclopedias, do the following.

  • Follow the references provided by the encyclopedia; this will help to verify the information given.
  • Consider whether the article is part of a larger project, where a number of people are contributing to the discussion. If it is, then it implies that the writers have more than a casual interest in the topic being written about.
  • Look to see if there is a rating for the information provided. If there is then this means that the information has undergone some sort of peer review and been given a rating. While not the same as an academic peer review, it can aid the judgment of the “quality” of the information.

The key point to remember, if you do use information that is found on the Internet, is that you are responsible for ensuring that it is both reliable and accurate. One way to make sure you are considering the quality of your sources is to produce an annotated bibliography as part of your Researcher’s reflection space. An annotated bibliography provides a concise summary of each source and some assessment of its value and relevance.

A good annotated bibliography will:

  • encourage you to think critically about the sources you are using and how these relate to  yourchosen research area in terms of their relevance 
  • provide a way to help you determine whether a source is of use to you in your research
  • allow you to keep track of your reading and enable you  to make informed decisions about which sources to use in writing your essay.

Twelve-step Plan for Researching the Extended Essay - Step 7

7.  Begin to identify how and where you will gather source material for your research.

how to list sources in an essay

Why you Need a Range of Sources

There are many information sources, from the obvious ones like books, magazines, newspapers and Internet sites to those you may not immediately think of such as maps, annual reports, conference proceedings and theses.  All sources have strengths and weaknesses and you should consider these when deciding on the most appropriate sources to use in your research.

Searching effectively in databases and on the Internet

By using effective search techniques you can find useful, relevant information without having to waste lots of time trawling through all those unwanted search results!

Use these tips to help you search a variety of information sources including databases, library catalogs, and the Internet.

  • If you have a choice, choose the Advanced Search  option, it will allow you to limit your search in a number of ways.
  • When planning your search, remember to use the keywords you identified in the 'Define' section.
  • Don't forget to use Boolean Operators (find more information on this page) to create your search strings.
  • The truncation symbol (*) can be used to find variations of a keyword that begin with the same letters.  For example econom* would find economy, economic, economics, economical etc.
  • Keep track of the searches you use so you don't go round in circles.  Note down particularly useful search strings.
  • Use quotation marks to group a number of words together (ie "Top Gear" would search for all results with the phrase 'Top Gear' but would ignore those where 'top' and 'gear' only appear seperately).
  • Verify important information by looking for the same information in a number of reliable sources.

Writing a good college essay can be tough and time-consuming. It will cost you several trips to the library, hours of pouring over your notes, and sleepless nights scouring online databases. ⏳

And while the internet is a huge pool of information, it is crucial to identify and use credible sources . So, the big question is: How can you find the right academic references for your college essay? 

Here’s a guide to finding essay sources that will impress your professor and get you that well-deserved A! 🔍

Start With Wikipedia 

Yes, we all know academic researchers frown upon Wikipedia since it’s user-generated (so anyone can write anything). But it’s actually a great springboard to get an overview of your essay topic . 💻

At the bottom of each Wikipedia page, you’ll find a treasure trove of legitimate sources and citations that you can use in your essay.

Check Out Primary Sources

Primary sources are the building blocks of any research project. They must serve as the foundation of your research, whereas secondary sources should inform and supplement the primary sources.

Primary sources are first-hand accounts on a subject, often unedited, that offer a close, personal overview of a topic. They encourage students to read between the lines and approach them with a critical mindset. 🤔

When analyzing primary sources, ask yourself key questions like, “Who is the intended audience?” or “What does the source tell me about the period?”

By considering these questions, you can effectively understand the historical context and cultural perspectives and avoid potential bias or inaccuracy . This will also help you develop well-supported arguments and strengthen your essay. 💪

Get the Most Out of the Library

Students may gravitate toward online research but the good old library is still a trusted source of information . In fact, 58 percent of Americans aged 16 and older have a library card — and for good reason! 

Library databases allow you to efficiently search for published information, such as magazines, journals, and newspaper articles . 

These sources contain scholarly articles by notable authors, journalists, and researchers. If you hit a paywall for a journal or newspaper, verify if your library has a subscription — problem solved! ✅

But the most underutilized tool in libraries is the staff. Librarians know all about research methods, using information systems, statistics, and management. 

They’re experts when it comes to finding the information you need. All you have to do is ask your university librarian for help finding top-tier resources on your essay topic. 📚

Use Academic Search Engines 

Let’s get this straight: It’s hard to write a research paper without consulting the internet . 

Most of us start our search with Google, but unfortunately, search engines don’t always churn out credible results . That’s why it’s crucial to explore other portals with an academic focus when searching for essay sources . ⚠️

Check out these options:

  • BASE : The Bielefeld Academic Search Engine (BASE) contains 4,000 sources and provides search results from more than 100 million documents. They also offer an advanced search option that allows users to narrow down their research. The BASE advanced search lets users use filters such as author names, publication dates, and document types to find more relevant results, saving time and improving academic research efficiency.
  • Refseek : A web search tool for students and researchers. You can access over a billion documents, books, newspapers, and journals without getting distracted by ads or sponsored links. 
  • Google Scholar : This connects you with hundreds of relevant scholarly journals. What’s more, it provides formatted citations in MLA, AP, or APA that you can export to RefWorks or BibTex. 
  • JSTOR : The platform provides a large collection of academic journals, books, and original sources from a variety of subjects.
  • PubMed : This includes articles from scholarly journals and research institutes with a focus on biomedical and life sciences research.
  • LexisNexis Academic : It focuses on researching legal and news-related subjects, including reports, legal publications, and court cases.

Opt for Digital Libraries and Databases 

Digital libraries have specialized collections in all fields of study. They are easy to access and contain millions of books, audiobooks, journals, and videos that can help you further your essay research. 

The best part? No more waiting for popular books to become available! Digital libraries let you read and download content instantly, anytime, anywhere, using your computer or phone . 📱 

Of course, there may be some occasions where you’ll find your university doesn’t have access to a particular online database.  

If you’ve found the perfect journal article but can’t get access, try emailing the professor who wrote it and ask for a PDF — most academics will be quite happy to provide you access to their work. 📧

Don’t Forget the Bibliography of Your Sources

After you have a list of credible sources, take a closer look at their citations. Seek out the primary sources these citations used for research. This will open up a new set of materials to work with for your essay. 🗒️ 

Plus, they often contain references to publications that make alternate viewpoints or offer diverse interpretations of the topic at hand. 

TIP: Once you start your research, you may find the same sources pop up over and over again. Consult Google Scholar to see the articles in a publication that are cited the most (along with who cited them). Make a list of these and incorporate them in your essay. 

Look Beyond Journals and Books

The world of research is your oyster, and with a diverse array of sources, your academic essay can shine if you dare to explore the unconventional.

Peruse through thrilling audio and video recordings that transport you to historic moments or cultural events, or explore interviews with experts who can add personal insights and real-life perspectives to your essay . 🎧

Incorporate variety in the resources you add to make your essay an interesting read. This will also show your professor that you’ve gone above and beyond to create a well-researched essay. 👌

Note: Critically assess the reliability and validity of sources outside of the conventional academic channels because their level of accuracy may vary. Always check the author’s qualifications, and the reputation of the source, and cross-reference information from various sources.

Learn to Quickly Evaluate a Source

Essays and research papers come with deadlines. In an ideal world, you would meticulously examine each potential essay source, but there’s a smarter way to do it to save time! 🗓️

Here’s a helpful approach to evaluating a source: First, read the abstract or introduction of the source to decide if it’s useful for your work . 

Then, take a look at the citations and references at the end of the source . You can also check the publication date to ensure the information is current.

If it’s an online source, check out the domain name. Sites with .edu domains are associated with educational facilities, while .gov domains belong to government agencies. These sources are generally reliable due to their affiliation with reputable institutions. 

Additionally, examine the author’s credentials and expertise in the field . Look for authors who have relevant academic backgrounds or professional experience related to the topic. ✍️

Lastly, consider the reputation of the publisher . Reputable publishers are known for maintaining high standards of quality and accuracy in their publications. 

Don’t know where to start? Check the publisher’s website, browse through its publication list, and look for details about its editorial board and reviewers. 🧐

Putting together a top-notch essay is a Herculean task — but if you can collect the right resources you’re already halfway there! 💯

  • Engaging With Sources Effectively

by acburton | Apr 30, 2024 | Resources for Students , Writing Resources

We’ve talked about the three ways to integrate sources effectively that allow writers to provide evidence and support for their argument, enter the scholarly conversation, and give credit to the original authors of the work that has helped and informed them. Sources also encourage writers to share their own knowledge and authority with others, help readers find additional sources related to the topic they are interested in, and protect you by giving credit where credit is due (thus avoiding plagiarism). In other words, sources are much more than just something we add on at the end of our writing!

When writing about a source or simply referencing it, we are positioning ourselves in response to, or in conversation with that source, with the goal of focusing our writing on our own argument/thesis. Sources do not stand on their own within a piece of writing and that is why, alongside finding strong and reputable sources worth responding to and making sure that we fully understand sources (even before writing about them), it is critical to engage with our sources in meaningful ways. But how exactly do we effectively engage with our sources in our writing?

Joseph Harris, in How To Do Things with Texts , presents four different ways of “rewriting the work of others”, three of which provide insight into the how of engaging sources. When a writer forwards the work of another writer, they are applying the concepts, topics, or terms from one reading, text, or situation to a different reading, text or situation. By countering the ideas found in source material, a writer argues “against the grain of a text” by underlining and countering ideas that a writer may be in disagreement with. Taking an approach is the adaptation of a theory or method from one writer to a new set of issues or texts. Harris’ book provides a thorough classification of methods to engage with a source. For something a little simpler, here are three basic ways you can get started effectively engaging with sources (Harris 5-7).

3 Basic Ways to Engage with Sources Effectively

  • Disagree and Explain Why. Persuade your reader that the argument or information in a source should be questioned or challenged.
  • Agree, But With Your Own Take. Add something new to the conversation. Expand a source’s insights or argument to a new situation or your own example. Provide new evidence and discuss new implications.
  • Agree and Disagree Simultaneously. This is a nuanced approach to complex sources or complex topics. You can, for example, agree with a source’s overall thesis, but disagree with some of its reasoning or evidence.

Remember that this is not an exhaustive list. When engaging with others’ sources as a way to support our own ideas and argument, it is crucial that we engage with critical thinking, nuance, and objectivity to ensure that we are constructing unbiased, thoughtful, and compelling arguments.

Some of the different areas throughout your essay that will benefit from effective engagement with source material include: your thesis statement, analysis, and conclusion.

  • Thesis Statement. The argument that you make in your thesis statement can challenge, weaken, support, or strengthen what is being argued by your source or sources.

Analysis. Thorough analysis in your body paragraphs emphasize the role of your argument in comparison to that found in your source material. Bring your analysis back to your thesis statement to reinforce the connection between the two.

  • Conclusion. Consider the “big picture” or “takeaways” to leave your reader with.

There are many other, sometimes optional, essay sections or writing styles that benefit from critical engagement with a source. These can include literature reviews, reflections, critiques, and so on.

Strategies for Engaging Critically From Start to Finish

  • Aim to dig deeper than surface level. Ask the ‘how’ and ‘why’ of a source, as well as ‘how’ and ‘why’ it is relevant to the topic at hand and the argument you are making.
  • Ask yourself if you’ve addressed every possible question, concern, critique, or “what if” that comes to mind; put yourself in the place of your readers.
  • Use TEAL body paragraph development as a template and guide for developing thorough analysis in your body paragraphs. Effectively engaging with your sources is essential to the analysis portion of the TEAL formula and to creating meaningful engagement with your sources.
  • Visit the Writing Center for additional support on crafting engaging analyses and for other ways to engage with your source material from thesis to conclusion.

Thousands Believe Covid Vaccines Harmed Them. Is Anyone Listening?

All vaccines have at least occasional side effects. But people who say they were injured by Covid vaccines believe their cases have been ignored.

Apoorva Mandavilli

By Apoorva Mandavilli

Apoorva Mandavilli spent more than a year talking to dozens of experts in vaccine science, policymakers and people who said they had experienced serious side effects after receiving a Covid-19 vaccine.

  • Published May 3, 2024 Updated May 4, 2024

Within minutes of getting the Johnson & Johnson Covid-19 vaccine, Michelle Zimmerman felt pain racing from her left arm up to her ear and down to her fingertips. Within days, she was unbearably sensitive to light and struggled to remember simple facts.

She was 37, with a Ph.D. in neuroscience, and until then could ride her bicycle 20 miles, teach a dance class and give a lecture on artificial intelligence, all in the same day. Now, more than three years later, she lives with her parents. Eventually diagnosed with brain damage, she cannot work, drive or even stand for long periods of time.

“When I let myself think about the devastation of what this has done to my life, and how much I’ve lost, sometimes it feels even too hard to comprehend,” said Dr. Zimmerman, who believes her injury is due to a contaminated vaccine batch .

The Covid vaccines, a triumph of science and public health, are estimated to have prevented millions of hospitalizations and deaths . Yet even the best vaccines produce rare but serious side effects . And the Covid vaccines have been given to more than 270 million people in the United States, in nearly 677 million doses .

Dr. Zimmerman’s account is among the more harrowing, but thousands of Americans believe they suffered serious side effects following Covid vaccination. As of April, just over 13,000 vaccine-injury compensation claims have been filed with the federal government — but to little avail. Only 19 percent have been reviewed. Only 47 of those were deemed eligible for compensation, and only 12 have been paid out, at an average of about $3,600 .

Some scientists fear that patients with real injuries are being denied help and believe that more needs to be done to clarify the possible risks.

“At least long Covid has been somewhat recognized,” said Akiko Iwasaki, an immunologist and vaccine expert at Yale University. But people who say they have post-vaccination injuries are “just completely ignored and dismissed and gaslighted,” she added.

Michelle Zimmerman sits on the floor of a ballroom where she used to dance, with a pair of dancing shoes next to her. She wears a dark skirt and a red velvet shirt.

In interviews and email exchanges conducted over several months, federal health officials insisted that serious side effects were extremely rare and that their surveillance efforts were more than sufficient to detect patterns of adverse events.

“Hundreds of millions of people in the United States have safely received Covid vaccines under the most intense safety monitoring in U.S. history,” Jeff Nesbit, a spokesman for the Department of Health and Human Services, said in an emailed statement.

But in a recent interview, Dr. Janet Woodcock, a longtime leader of the Food and Drug Administration, who retired in February, said she believed that some recipients had experienced uncommon but “serious” and “life-changing” reactions beyond those described by federal agencies.

“I feel bad for those people,” said Dr. Woodcock, who became the F.D.A.’s acting commissioner in January 2021 as the vaccines were rolling out. “I believe their suffering should be acknowledged, that they have real problems, and they should be taken seriously.”

“I’m disappointed in myself,” she added. “I did a lot of things I feel very good about, but this is one of the few things I feel I just didn’t bring it home.”

Federal officials and independent scientists face a number of challenges in identifying potential vaccine side effects.

The nation’s fragmented health care system complicates detection of very rare side effects, a process that depends on an analysis of huge amounts of data. That’s a difficult task when a patient may be tested for Covid at Walgreens, get vaccinated at CVS, go to a local clinic for minor ailments and seek care at a hospital for serious conditions. Each place may rely on different health record systems.

There is no central repository of vaccine recipients, nor of medical records, and no easy to way to pool these data. Reports to the largest federal database of so-called adverse events can be made by anyone, about anything. It’s not even clear what officials should be looking for.

“I mean, you’re not going to find ‘brain fog’ in the medical record or claims data, and so then you’re not going to find” a signal that it may be linked to vaccination, Dr. Woodcock said. If such a side effect is not acknowledged by federal officials, “it’s because it doesn’t have a good research definition,” she added. “It isn’t, like, malevolence on their part.”

The government’s understaffed compensation fund has paid so little because it officially recognizes few side effects for Covid vaccines. And vaccine supporters, including federal officials, worry that even a whisper of possible side effects feeds into misinformation spread by a vitriolic anti-vaccine movement.

‘I’m Not Real’

Patients who believe they experienced serious side effects say they have received little support or acknowledgment.

Shaun Barcavage, 54, a nurse practitioner in New York City who has worked on clinical trials for H.I.V. and Covid, said that ever since his first Covid shot, merely standing up sent his heart racing — a symptom suggestive of postural orthostatic tachycardia syndrome , a neurological disorder that some studies have linked to both Covid and, much less often, vaccination .

He also experienced stinging pain in his eyes, mouth and genitals, which has abated, and tinnitus, which has not.

“I can’t get the government to help me,” Mr. Barcavage said of his fruitless pleas to federal agencies and elected representatives. “I am told I’m not real. I’m told I’m rare. I’m told I’m coincidence.”

Renee France, 49, a physical therapist in Seattle, developed Bell’s palsy — a form of facial paralysis, usually temporary — and a dramatic rash that neatly bisected her face. Bell’s palsy is a known side effect of other vaccines, and it has been linked to Covid vaccination in some studies.

But Dr. France said doctors were dismissive of any connection to the Covid vaccines. The rash, a bout of shingles, debilitated her for three weeks, so Dr. France reported it to federal databases twice.

“I thought for sure someone would reach out, but no one ever did,” she said.

Similar sentiments were echoed in interviews, conducted over more than a year, with 30 people who said they had been harmed by Covid shots. They described a variety of symptoms following vaccination, some neurological, some autoimmune, some cardiovascular.

All said they had been turned away by physicians, told their symptoms were psychosomatic, or labeled anti-vaccine by family and friends — despite the fact that they supported vaccines.

Even leading experts in vaccine science have run up against disbelief and ambivalence.

Dr. Gregory Poland, 68, editor in chief of the journal Vaccine, said that a loud whooshing sound in his ears had accompanied every moment since his first shot, but that his entreaties to colleagues at the Centers for Disease Control and Prevention to explore the phenomenon, tinnitus, had led nowhere.

He received polite responses to his many emails, but “I just don’t get any sense of movement,” he said.

“If they have done studies, those studies should be published,” Dr. Poland added. In despair that he might “never hear silence again,” he has sought solace in meditation and his religious faith.

Dr. Buddy Creech, 50, who led several Covid vaccine trials at Vanderbilt University, said his tinnitus and racing heart lasted about a week after each shot. “It’s very similar to what I experienced during acute Covid, back in March of 2020,” Dr. Creech said.

Research may ultimately find that most reported side effects are unrelated to the vaccine, he acknowledged. Many can be caused by Covid itself.

“Regardless, when our patients experience a side effect that may or may not be related to the vaccine, we owe it to them to investigate that as completely as we can,” Dr. Creech said.

Federal health officials say they do not believe that the Covid vaccines caused the illnesses described by patients like Mr. Barcavage, Dr. Zimmerman and Dr. France. The vaccines may cause transient reactions, such as swelling, fatigue and fever, according to the C.D.C., but the agency has documented only four serious but rare side effects .

Two are associated with the Johnson & Johnson vaccine, which is no longer available in the United States: Guillain-Barré syndrome , a known side effect of other vaccines , including the flu shot; and a blood-clotting disorder.

The C.D.C. also links mRNA vaccines made by Pfizer-BioNTech and Moderna to heart inflammation, or myocarditis, especially in boys and young men. And the agency warns of anaphylaxis, or severe allergic reaction, which can occur after any vaccination.

Listening for Signals

Agency scientists are monitoring large databases containing medical information on millions of Americans for patterns that might suggest a hitherto unknown side effect of vaccination, said Dr. Demetre Daskalakis, director of the C.D.C.’s National Center for Immunization and Respiratory Diseases.

“We toe the line by reporting the signals that we think are real signals and reporting them as soon as we identify them as signals,” he said. The agency’s systems for monitoring vaccine safety are “pretty close” to ideal, he said.

how to list sources in an essay

Those national surveillance efforts include the Vaccine Adverse Event Reporting System (VAERS). It is the largest database, but also the least reliable: Reports of side effects can be submitted by anyone and are not vetted, so they may be subject to bias or manipulation.

The system contains roughly one million reports regarding Covid vaccination, the vast majority for mild events, according to the C.D.C.

Federal researchers also comb through databases that combine electronic health records and insurance claims on tens of millions of Americans. The scientists monitor the data for 23 conditions that may occur following Covid vaccination. Officials remain alert to others that may pop up, Dr. Daskalakis said.

But there are gaps, some experts noted. The Covid shots administered at mass vaccination sites were not recorded in insurance claims databases, for example, and medical records in the United States are not centralized.

“It’s harder to see signals when you have so many people, and things are happening in different parts of the country, and they’re not all collected in the same system,” said Rebecca Chandler, a vaccine safety expert at the Coalition for Epidemic Preparedness Innovations.

An expert panel convened by the National Academies concluded in April that for the vast majority of side effects, there was not enough data to accept or reject a link.

Asked at a recent congressional hearing whether the nation’s vaccine-safety surveillance was sufficient, Dr. Peter Marks, director of the F.D.A.’s Center for Biologics Evaluation and Research, said, “I do believe we could do better.”

In some countries with centralized health care systems, officials have actively sought out reports of serious side effects of Covid vaccines and reached conclusions that U.S. health authorities have not.

In Hong Kong, the government analyzed centralized medical records of patients after vaccination and paid people to come forward with problems. The strategy identified “a lot of mild cases that other countries would not otherwise pick up,” said Ian Wong, a researcher at the University of Hong Kong who led the nation’s vaccine safety efforts.

That included the finding that in rare instances — about seven per million doses — the Pfizer-BioNTech vaccine triggered a bout of shingles serious enough to require hospitalization.

The European Medicines Agency has linked the Pfizer and Moderna vaccines to facial paralysis, tingling sensations and numbness. The E.M.A. also counts tinnitus as a side effect of the Johnson & Johnson vaccine, although the American health agencies do not. There are more than 17,000 reports of tinnitus following Covid vaccination in VAERS.

Are the two linked? It’s not clear. As many as one in four adults has some form of tinnitus. Stress, anxiety, grief and aging can lead to the condition, as can infections like Covid itself and the flu.

There is no test or scan for tinnitus, and scientists cannot easily study it because the inner ear is tiny, delicate and encased in bone, said Dr. Konstantina Stankovic, an otolaryngologist at Stanford University.

Still, an analysis of health records from nearly 2.6 million people in the United States found that about 0.04 percent , or about 1,000, were diagnosed with tinnitus within three weeks of their first mRNA shot. In March, researchers in Australia published a study linking tinnitus and vertigo to the vaccines .

The F.D.A. is monitoring reports of tinnitus, but “at this time, the available evidence does not suggest a causal association with the Covid-19 vaccines,” the agency said in a statement.

Despite surveillance efforts, U.S. officials were not the first to identify a significant Covid vaccine side effect: myocarditis in young people receiving mRNA vaccines. It was Israeli authorities who first raised the alarm in April 2021. Officials in the United States said at the time that they had not seen a link.

On May 22, 2021, news broke that the C.D.C. was investigating a “relatively few” cases of myocarditis. By June 23, the number of myocarditis reports in VAERS had risen to more than 1,200 — a hint that it is important to tell doctors and patients what to look for.

Later analyses showed that the risk for myocarditis and pericarditis, a related condition, is highest after a second dose of an mRNA Covid vaccine in adolescent males aged 12 to 17 years.

In many people, vaccine-related myocarditis is transient. But some patients continue to experience pain, breathlessness and depression, and some show persistent changes on heart scans . The C.D.C. has said there were no confirmed deaths related to myocarditis, but in fact there have been several accounts of deaths reported post-vaccination .

Pervasive Misinformation

The rise of the anti-vaccine movement has made it difficult for scientists, in and out of government, to candidly address potential side effects, some experts said. Much of the narrative on the purported dangers of Covid vaccines is patently false, or at least exaggerated, cooked up by savvy anti-vaccine campaigns.

Questions about Covid vaccine safety are core to Robert F. Kennedy Jr.’s presidential campaign. Citing debunked theories about altered DNA, Florida’s surgeon general has called for a halt to Covid vaccination in the state.

“The sheer nature of misinformation, the scale of misinformation, is staggering, and anything will be twisted to make it seem like it’s not just a devastating side effect but proof of a massive cover-up,” said Dr. Joshua Sharfstein, a vice dean at Johns Hopkins University.

Among the hundreds of millions of Americans who were immunized for Covid, some number would have had heart attacks or strokes anyway. Some women would have miscarried. How to distinguish those caused by the vaccine from those that are coincidences? The only way to resolve the question is intense research .

But the National Institutes of Health is conducting virtually no studies on Covid vaccine safety, several experts noted. William Murphy, a cancer researcher who worked at the N.I.H. for 12 years, has been prodding federal health officials to initiate these studies since 2021.

The officials each responded with “that very tired mantra: ‘But the virus is worse,’” Dr. Murphy recalled. “Yes, the virus is worse, but that doesn’t obviate doing research to make sure that there may be other options.”

A deeper understanding of possible side effects, and who is at risk for them, could have implications for the design of future vaccines, or may indicate that for some young and healthy people, the benefit of Covid shots may no longer outweigh the risks — as some European countries have determined.

Thorough research might also speed assistance to thousands of Americans who say they were injured.

The federal government has long run the National Vaccine Injury Compensation Program , designed to compensate people who suffer injuries after vaccination. Established more than three decades ago, the program sets no limit on the amounts awarded to people found to have been harmed.

But Covid vaccines are not covered by that fund because Congress has not made them subject to the excise tax that pays for it. Some lawmakers have introduced bills to make the change.

Instead, claims regarding Covid vaccines go to the Countermeasures Injury Compensation Program . Intended for public health emergencies, this program has narrow criteria to pay out and sets a limit of $50,000, with stringent standards of proof.

It requires applicants to prove within a year of the injury that it was “the direct result” of getting the Covid vaccine, based on “compelling, reliable, valid, medical, and scientific evidence.”

The program had only four staff members at the beginning of the pandemic, and now has 35 people evaluating claims. Still, it has reviewed only a fraction of the 13,000 claims filed, and has paid out only a dozen.

Dr. Ilka Warshawsky, a 58-year-old pathologist, said she lost all hearing in her right ear after a Covid booster shot. But hearing loss is not a recognized side effect of Covid vaccination.

The compensation program for Covid vaccines sets a high bar for proof, she said, yet offers little information on how to meet it: “These adverse events can be debilitating and life-altering, and so it’s very upsetting that they’re not acknowledged or addressed.”

Dr. Zimmerman, the neuroscientist, submitted her application in October 2021 and provided dozens of supporting medical documents. She received a claim number only in January 2023.

In adjudicating her claim for workers’ compensation, Washington State officials accepted that Covid vaccination caused her injury, but she has yet to get a decision from the federal program.

One of her therapists recently told her she might never be able to live independently again.

“That felt like a devastating blow,” Dr. Zimmerman said. “But I’m trying not to lose hope there will someday be a treatment and a way to cover it.”

APA style dictates that authors are named with their last name followed by their initials; publication year goes between parentheses, followed by a period. The title of the article is in sentence-case, meaning only the first word and proper nouns in the title are capitalized. The periodical title is run in title case, and is followed by the volume number which, with the title, is also italicized. If a DOI has been assigned to the article that you are using, you should include this after the page numbers for the article. If no DOI has been assigned and you are accessing the periodical online, use the URL of the website from which you are retrieving the periodical.

Article in Print Journal

Note: APA 7 advises writers to include a DOI (if available), even when using the print source. The example above assumes no DOI is available.

Article in Electronic Journal

Note :  This content also appears on Reference List: Online Media .

As noted above, when citing an article in an electronic journal, include a DOI if one is associated with the article.

DOIs may not always be available. In these cases, use a URL. Many academic journals provide stable URLs that function similarly to DOIs. These are preferable to ordinary URLs copied and pasted from the browser's address bar.
