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):

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!

Reference List: Basic Rules

OWL logo

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.

This resourse, revised according to the 7 th  edition APA Publication Manual, offers basic guidelines for formatting the reference list at the end of a standard APA research paper. Most sources follow fairly straightforward rules. However, because sources obtained from academic journals  carry special weight in research writing, these sources are subject to special rules . Thus, this page presents basic guidelines for citing academic journals separate from its "ordinary" basic guidelines. This distinction is made clear below.

Note:  Because the information on this page pertains to virtually all citations, we've highlighted one important difference between APA 6 and APA 7 with an underlined note written in red.  For more information, please consult the   Publication Manual of the American Psychological Association , (7 th  ed.).

Formatting a Reference List

Your reference list should appear at the end of your paper. It provides the information necessary for a reader to locate and retrieve any source you cite in the body of the paper. Each source you cite in the paper must appear in your reference list; likewise, each entry in the reference list must be cited in your text.

Your references should begin on a new page separate from the text of the essay; label this page "References" in bold, centered at the top of the page (do NOT underline or use quotation marks for the title). All text should be double-spaced just like the rest of your essay.

Basic Rules for Most Sources

  • All lines after the first line of each entry in your reference list should be indented one-half inch from the left margin. This is called hanging indentation.
  • All authors' names should be inverted (i.e., last names should be provided first).
  • For example, the reference entry for a source written by Jane Marie Smith would begin with "Smith, J. M."
  • If a middle name isn't available, just initialize the author's first name: "Smith, J."
  • Give the last name and first/middle initials for all authors of a particular work up to and including 20 authors ( this is a new rule, as APA 6 only required the first six authors ). Separate each author’s initials from the next author in the list with a comma. Use an ampersand (&) before the last author’s name. If there are 21 or more authors, use an ellipsis (but no ampersand) after the 19th author, and then add the final author’s name.
  • Reference list entries should be alphabetized by the last name of the first author of each work.
  • For multiple articles by the same author, or authors listed in the same order, list the entries in chronological order, from earliest to most recent.
  • Note again that the titles of academic journals are subject to special rules. See section below.
  • Italicize titles of longer works (e.g., books, edited collections, names of newspapers, and so on).
  • Do not italicize, underline, or put quotes around the titles of shorter works such as chapters in books or essays in edited collections.

Basic Rules for Articles in Academic Journals

  • Present journal titles in full.
  • Italicize journal titles.
  • For example, you should use  PhiloSOPHIA  instead of  Philosophia,  or  Past & Present   instead of  Past and Present.
  • This distinction is based on the type of source being cited. Academic journal titles have all major words capitalized, while other sources' titles do not.
  • Capitalize   the first word of the titles and subtitles of   journal articles , as well as the   first word after a colon or a dash in the title, and   any proper nouns .
  • Do not italicize or underline the article title.
  • Deep blue: The mysteries of the Marianas Trench.
  • Oceanographic Study: A Peer-Reviewed Publication

Please note:  While the APA manual provides examples of how to cite common types of sources, it does not cover all conceivable sources. If you must cite a source that APA does not address, the APA suggests finding an example that is similar to your source and using that format. For more information, see page 282 of the   Publication Manual of the American Psychological Association , 7 th  ed.

Referencing styles

Author-date citations (Harvard) Numbered notes Numbered reference citations (Vancouver) OSCOLA

Introduction

Source references are vital to academic works (both print and digital) and so it is essential that they are clear, complete, and consistently formatted. Online bibliographical material is hyperlinked to provide readers with instant access to relevant sources or additional information.

Reference styles vary greatly across disciplines. This section details the main reference styles supported by OUP (Harvard, Vancouver, and OSCOLA) and provides examples that you can follow. If you are in doubt, your OUP editorial contact will be able to advise you on the best citation system for your text.

Author-date citations (Harvard)

The author-date style is an efficient and clear method of providing citations to published sources, which appear in a reference list at the end of the chapter or book. No superscripts are used, which means that reordering of the text does not require renumbering of notes. Instead of superscript numbers, a parenthetical citation (consisting of author name and date of publication) appears in the text and leads the reader to a full entry in a reference list that appears at the end of the chapter or book.

The method works particularly well when most of your citations are to published books or journal articles. It works less well if you are citing a lot of unauthored material or untraditional sources. Unlike numbered notes, author-date citations cannot accommodate translations or commentary outside the main text, although it is possible to combine author-date citations (for bibliographic citations) with numbered notes (for explanatory text).

In-text citation

References are cited within the text by including the author’s last name and a date parenthetically. A page number can be added if needed. If the author’s name appears in the sentence containing the citation, you need only use the date. Complete bibliographical reference information is listed at the end of the chapter or text.

Up to two author names can be used in the in-text citation. When citing a work with three or more authors, use the first author’s last name plus ‘et al.’

If you cite multiple references by the same author that were published in the same year, distinguish between them by adding labels (e.g. ‘a’ and ‘b’) to the year, in both the citation and the reference list.

Structure of the reference list

The reference list appears at the end of the chapter or text in alphabetical order. The name of the first author is inverted. In science literature, initials are often used in place of author first names.

The bibliographic elements listed below are required for the most common types of reference citations. Additional elements are mentioned that may be optional or to be used in only certain instances (e.g. a page number or other locator that is required if you are quoting a precise part of a large work, but not if the reference is to the work as a whole). Consistency in application is important.

Do not use long dashes (“—") to substitute for the name of an author who is identified in the bibliography due to how that entry will be linked in digital versions. Because the entry may not appear immediately following the entry with the full name, repeat the name in full.

Psychoanalytic studies, along with other literary and cultural texts, not only contribute to the new discourse of the jungle but also reflect the imperialist history that brings West Europeans and Americans into contact with the geographic jungles of India, Africa, and other parts of the world (Rogers et al. 2010, 1). This colonial context needs to be sketched here as well in order to reveal how the birth of the jungle eventually produces new constructions of sexuality in the United States. Billops (1999a) notes that the word ‘jungle’ comes from the Hindi and Marathi word jangal, meaning ‘desert’, ‘waste’, ‘forest’; as well as from the Sanskrit jangala, meaning ‘dry’, ‘dry ground’, or ‘desert’. Its first appearance in English is in 1776, with its meaning already shifted towards what might be more recognizable today: ‘Land overgrown with underwood, long grass, or tangled vegetation; also, the luxuriant and often almost impenetrable growth of vegetation covering such a tract’ (Dreft and Smithers 1978, 87). Brought into English as a result of an imperialist presence in India, ‘jungle’ is intimately related to the larger rise of Western imperialism around the world, particularly in the nineteenth century (Billops 1999b). Western powers such as Britain and France went from controlling 35 per cent of the earth’s surface in 1800 to, by 1914, ‘a grand total of roughly 85 per cent of the earth as colonies, protectorates, dependencies, dominions, and commonwealths’ (Said 1993, ch.2, ‘Colonial impacts’).

Reference list vs. bibliography

Note that a reference list in the author-date system can contain only items that are actually cited in the work. The reference list must contain all of those items. This differs from a bibliography in the numbered-note system, which can contain both cited items and items of interest that have not been specifically cited. If there are uncited works that you would like to draw to the reader’s attention, these can be placed after the references in a separate listed titled ‘Further reading’.

Numbered notes

Using numbered notes is a common method of citing sources, particularly in the humanities. Sequential superscript numbers appear in the text to direct the reader to bibliographic or explanatory information that appears in a note.

This is a flexible style that allows authors to combine bibliographic information with annotation, translation, or other commentary. Scholars who frequently cite unpublished material will find numbered notes more useful than author-date citations.

Endnotes or footnotes?

In print publishing, notes can be placed at the bottom of the page as footnotes or at the end of a chapter or book in a separate section as endnotes.

Footnotes are preferred in cases where the information in the note is important enough that readers need it to fully engage with the material. Please note that in a digital context, footnotes in the traditional sense are not possible. Depending on the format, footnotes can appear at the end of a section or chapter, or they may be viewed by clicking or hovering over the superscript numbers in the text to display individual footnotes.

Endnotes are a better choice in print if the material in the notes does not need immediate engagement by the reader. For digital publications where individual chapters may be made available to readers, the notes should appear with the chapter, rather than separately at the end of the work. This varies according to discipline, so please consult your OUP editorial contact if you are unsure.

The formatting of bibliographic information is identical for footnotes and endnotes.

Please use the following guidance:

  • Numbered notes appear sequentially in the text as superscripts, ideally at the end of a sentence, following the closing punctuation.
  • Use Arabic numerals.
  • Numbers should restart at 1 at the beginning of each chapter and run consecutively to the end of each chapter. Do not start renumbering within a chapter (e.g. per page or per double-page spread) or use asterisks, as this will cause confusion in a digital environment.
  • Do not number the notes continuously throughout a book, because a later change would necessitate extensive renumbering.

Note structure and format

Required bibliographic elements are given below for the most common types of reference citations, along with optional elements that if used, must be consistent.

  • Page numbers are useful locators when referencing in print publications.
  • Give page ranges using the fewest number of figures as possible (e.g. pp. 126–27, not pp. 126–127).
  • When referencing a digital publication, you may not have access to a print page number. Cite a specific locator (e.g. chapter titles and sub-headings). Do not use location numbers from a proprietary e-reader (e.g. Kindle location numbers).
  • Edition numbers are not required when citing a first edition but are necessary for subsequent editions.

Numbered notes in combination with a bibliography

It is possible to combine notes and bibliography so that all the notes, including the first reference, are short citations that lead the reader to a full citation in the bibliography. This system results in shorter notes and less work for the reader, since complete information is easily available in the alphabetical bibliography and need not be hunted for through all the chapter notes. This requires that all cited sources appear in a bibliography, which can also contain works that are not cited but are germane to the topic.

Structure of a bibliography entry

Bibliographies are structured similarly to notes, but there are some important differences. The first author name (and only the first) is inverted for alphabetization. Punctuation format also varies slightly between notes and bibliographic entries.

Do not use long dashes (e.g. “—") to substitute for an author’s name if it is repeated in the bibliography. Repeat the name in full because in a digital version, the shortened entry may not follow the complete one immediately.

Numbered reference citations (Vancouver)

Numbered reference citations (also known as author–number or Vancouver references) are used in scientific and medical texts. In this system, each reference used is assigned a number. When that reference is cited in the text, its number appears, either in parentheses or brackets or as a superscript. All cited references appear in a numbered reference list at the end of the chapter or book.

An advantage of numbered references over the author–date style is that less space in the main text is required for in-text citations. The system also avoids ambiguity in the case of two works by the same author published the same year, an occasional issue in author–date citations. A disadvantage is that late addition or removal of references usually requires renumbering of both the reference list and the citations. Numbered reference citations cannot be used to provide commentary or other explanatory material to the text.

References are cited within the text by using a number in a superscript, in parentheses, or in square brackets. Although each of these variants is acceptable, only one can be used in a single text. The examples in this guide will enclose citation numbers in parentheses. Note that although citations are numbered in the order of their first appearance in the text, non-consecutive note numbers are possible, to allow references to be cited more than once. Citations can take the form of a range: for example (4–7) would cite references 4, 5, 6, and 7 simultaneously. If it is necessary to cite specific page numbers that are not present in the reference list, page numbers can be inserted into the citation: for example (4p6, 5pp1–11).

Please note the following:

  • Author first names are usually given as initials only, with no full stops (e.g. “AN” not “A.N.”) between initials. In the case of multiple authors, you can list up to six full names; for more than six authors, list the first three plus ‘et al’. All author names are inverted (i.e. last name, first name).
  • Names of journals can be abbreviated, as in the examples in this section, but must follow the standard abbreviations used by PubMed. Journal article titles are given without quotation marks and in sentence-style capitalization.
  • Do not use long dashes (e.g. “—") to substitute for the name of an author whose name is repeated in the bibliography. Repeat the name in full because linking in a digital publication may not immediately follow the entry with the full name.
  • Citations are numbered in the order in which they first appear in the text.

Required bibliographic elements are given below for the most common types of reference citations, along with optional elements (if used, be consistent). Other elements below are required if applicable (for example, you need a page number or other locator if you are quoting a precise part of a large work, but you can skip it if the reference is to the work as a whole).

Example: Numbered reference citations and reference list—British style

Colorectal cancer (cRc) is one of the most common malignancies and the second leading cause of death from cancer in Europe and North America (1). While early stage cRc is associated with an excellent 5-year survival rate (90% for localized disease), approximately 20% of patients present with metastatic disease, and many patients diagnosed with stage ii or iii cancer will experience a recurrence and develop distant metastases (2). At present, established clinico-pathological criteria are used to estimate risks of recurrence in stage ii and iii disease, and this is routinely used in the selection of patients or adjuvant systemic therapy following surgical resection. The clinical outcome of patients who receive such adjuvant treatment can, however, vary widely, when additional molecular factors are taken into consideration. Identification of novel prognostic markers is, therefore, vital in improving the prognosis of this disease (3). One of the recently described substances important for angiogenesis is endoglin. Endoglin, also known as cD105, is a receptor for transforming growth factor-ß1 molecule, which binds preferentially to the activated endothelial cells that participate in tumour angiogenesis, with weak or negative expression in vascular endothelium of normal tissues. Endoglin is induced by hypoxia. Therefore, it is very useful for assessment of neo-angiogenesis of malignant neoplasms (4–6). Many reports indicate that endoglin assessed immunohistochemically in colorectal cancer correlates not only with tumour microvessel density, but also with survival. It has also been reported as a valuable parameter predicting patients having an increased risk of developing metastatic disease. Endoglin is expressed not only on cell surfaces since its soluble form (sol-end) can be detected also in blood (4–7). A few studies evaluated the clinical significance of elevated sol-end levels in colorectal cancer patients (7).

A Quick Guide to Harvard Referencing | Citation Examples

Published on 14 February 2020 by Jack Caulfield . Revised on 15 September 2023.

Referencing is an important part of academic writing. It tells your readers what sources you’ve used and how to find them.

Harvard is the most common referencing style used in UK universities. In Harvard style, the author and year are cited in-text, and full details of the source are given in a reference list .

Harvard in-text citation, creating a harvard reference list, harvard referencing examples, referencing sources with no author or date, frequently asked questions about harvard referencing.

A Harvard in-text citation appears in brackets beside any quotation or paraphrase of a source. It gives the last name of the author(s) and the year of publication, as well as a page number or range locating the passage referenced, if applicable:

Note that ‘p.’ is used for a single page, ‘pp.’ for multiple pages (e.g. ‘pp. 1–5’).

An in-text citation usually appears immediately after the quotation or paraphrase in question. It may also appear at the end of the relevant sentence, as long as it’s clear what it refers to.

When your sentence already mentions the name of the author, it should not be repeated in the citation:

Sources with multiple authors

When you cite a source with up to three authors, cite all authors’ names. For four or more authors, list only the first name, followed by ‘ et al. ’:

Sources with no page numbers

Some sources, such as websites , often don’t have page numbers. If the source is a short text, you can simply leave out the page number. With longer sources, you can use an alternate locator such as a subheading or paragraph number if you need to specify where to find the quote:

Multiple citations at the same point

When you need multiple citations to appear at the same point in your text – for example, when you refer to several sources with one phrase – you can present them in the same set of brackets, separated by semicolons. List them in order of publication date:

Multiple sources with the same author and date

If you cite multiple sources by the same author which were published in the same year, it’s important to distinguish between them in your citations. To do this, insert an ‘a’ after the year in the first one you reference, a ‘b’ in the second, and so on:

A bibliography or reference list appears at the end of your text. It lists all your sources in alphabetical order by the author’s last name, giving complete information so that the reader can look them up if necessary.

The reference entry starts with the author’s last name followed by initial(s). Only the first word of the title is capitalised (as well as any proper nouns).

Harvard reference list example

Sources with multiple authors in the reference list

As with in-text citations, up to three authors should be listed; when there are four or more, list only the first author followed by ‘ et al. ’:

Reference list entries vary according to source type, since different information is relevant for different sources. Formats and examples for the most commonly used source types are given below.

  • Entire book
  • Book chapter
  • Translated book
  • Edition of a book

Journal articles

  • Print journal
  • Online-only journal with DOI
  • Online-only journal with no DOI
  • General web page
  • Online article or blog
  • Social media post

Sometimes you won’t have all the information you need for a reference. This section covers what to do when a source lacks a publication date or named author.

No publication date

When a source doesn’t have a clear publication date – for example, a constantly updated reference source like Wikipedia or an obscure historical document which can’t be accurately dated – you can replace it with the words ‘no date’:

Note that when you do this with an online source, you should still include an access date, as in the example.

When a source lacks a clearly identified author, there’s often an appropriate corporate source – the organisation responsible for the source – whom you can credit as author instead, as in the Google and Wikipedia examples above.

When that’s not the case, you can just replace it with the title of the source in both the in-text citation and the reference list:

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.

A Harvard in-text citation should appear in brackets every time you quote, paraphrase, or refer to information from a source.

The citation can appear immediately after the quotation or paraphrase, or at the end of the sentence. If you’re quoting, place the citation outside of the quotation marks but before any other punctuation like a comma or full stop.

In Harvard referencing, up to three author names are included in an in-text citation or reference list entry. When there are four or more authors, include only the first, followed by ‘ et al. ’

Though the terms are sometimes used interchangeably, there is a difference in meaning:

  • A reference list only includes sources cited in the text – every entry corresponds to an in-text citation .
  • A bibliography also includes other sources which were consulted during the research but not cited.

How to Reference Essays

Last Updated: January 8, 2024 Fact Checked

This article was co-authored by Alexander Peterman, MA . Alexander Peterman is a Private Tutor in Florida. He received his MA in Education from the University of Florida in 2017. There are 14 references cited in this article, which can be found at the bottom of the page. This article has been fact-checked, ensuring the accuracy of any cited facts and confirming the authority of its sources. This article has been viewed 359,359 times.

When you begin writing a research essay, you must take into account the format of your writing and reference pages. There are several reference styles that may be assigned to you, including MLA (Modern Language Association), APA (American Psychological Association), and Chicago. Each one has its own set of rules. There's no need to familiarize yourself with all 3 unless you have to, but you do need to learn at least one if you’re in any field involving academic writing. Here are summaries of each style to help you start your essay on the right track.

Referencing Essays Templates

reference types essay

  • You will need a citation directly after every sentence (or group of sentences if you're citing the same source in multiple consecutive sentences) containing information you didn't think of yourself. These include: paraphrases, facts, statistics, quotes, and examples.
  • An in-text citation using MLA will simply have the author last name (or title if no author) followed by the page number. No comma between author and page number. For example: (Richards 456) Richards is the author last name, and 456 is the page number.
  • If you have an author name (or title, if no author) but no page number, simply use author last name (or title).

Step 2 Gather information.

  • The easiest way to keep track of MLA citations while doing research is to copy and paste copyright information into a word processing document as you go, or to write it down in a notebook.
  • Things to include for any source are author(s), date published, publisher, page number, volume and issue number, website, date accessed, anything that appears on the copyright page or indicates how to find it again. [2] X Trustworthy Source Purdue Online Writing Lab Trusted resource for writing and citation guidelines Go to source

Step 3 Organize the sources.

  • As an example, the format for a standard book citation using MLA style is as follows: Last name of author, First name. Title of Book. City published: Publisher Name, Year published. Source Medium.
  • An MLA website citation looks like the following. If there's no author listed, begin citation with the name of the page: Last name, first name. "Page Title." Website Title. Publisher. Date published. Source Medium. Date accessed.
  • An MLA scholarly article citation looks like the following: Last name, First name. "Title of Article." Title of Journal . Volume.Issue (Year): page numbers. Source Medium.
  • Write the title of the main work (book, magazine, journal, website, etc.) in italics, or underline if you’re writing references by hand.
  • Chapter or article titles should be in quotation marks.

Step 4 Alphabetize the list.

  • If there is no author listed, as is common on websites, simply skip the author’s name and begin the entry with the title of the work.
  • Alphabetize by the first letter that appears in the entry, whether it has an author name or not.

Step 5 Format the Works Cited page.

  • The formatting should be in Times New Roman font, size 12, with “Works Cited” centered at the top of a new page.
  • Each entry should have hanging indent, meaning all lines below the first line are indented by half an inch.
  • Make sure there is a period after each section of the citations. A period should always end the citation.

Step 1 Cite while you write.

  • Place a parenthetical citation at the end of every sentence (or group of sentences if you're using the same source for multiple consecutive sentences) containing information you didn't know before doing research.
  • An in-text citation using APA will simply have the author last name (or title if no author) followed by the year it was published. No comma between name and year. For example: (Richards 2005) Richards is the author last name, and 2005 is the year.
  • If you have an author name (or title if no author) but no page number, simply use author last name (or title). This is common when citing websites.
  • APA document formatting is very important. APA papers are divided up into 4 sections: the title page, the abstract, the main body, and the references page. The citations of a research paper using APA appear in the References section, the last portion of an APA document. [7] X Research source

Step 2 Gather information.

  • To form APA reference page citations, you will need such information as author name(s), date published, website URL, date you accessed the website, title of work, and so on. [8] X Trustworthy Source Purdue Online Writing Lab Trusted resource for writing and citation guidelines Go to source

Step 3 Organize the list.

  • For example, the format for an APA reference of a scholarly journal article is as follows: Author last name, First initial. (Year published). Article or chapter title. Journal or book title, Issue number , page number range. [10] X Trustworthy Source Purdue Online Writing Lab Trusted resource for writing and citation guidelines Go to source
  • The format for an APA book reference looks like: Last name, First name. (Year.) Title of Book: Capital letter also for subtitle . Location: Publisher.
  • The format for an APA website reference looks like: Author, A.A. First name, & Author, B.B. (Date published.) Title of article. In Title of webpage or larger document or book (chapter or section number). Retrieved from URL address

Step 4 Format the page.

  • Capitalize the author's last name and first initial, followed by a period.
  • Only capitalize the first word of a journal article title, unless the title contains a proper noun (called sentence case). Titles of books should preserve the published capitalization.
  • Capitalize the city of publication, and use correct state abbreviations for states. Also capitalize the name of the publisher and end the reference with a period.
  • The title of larger works, whether a book, journal, website, or magazine, is in italics (or underlined if handwriting), as is the issue number that appears right after the title. Titles for shorter works like articles and chapters should not have any indicative punctuation in an APA entry. [12] X Trustworthy Source Purdue Online Writing Lab Trusted resource for writing and citation guidelines Go to source
  • A period should end all citations.

Using Chicago Manual of Style

Step 1 Cite while you write.

  • For Notes and Bibliography, you will use a superscript at the instance of each quote in the text with a corresponding footnote at the end of the page. All footnotes are compiled into endnotes at the end of the work, on the bibliography page. [14] X Trustworthy Source Purdue Online Writing Lab Trusted resource for writing and citation guidelines Go to source
  • For Author Date, you will use parenthetical in-text citations that include author last name and year published, using no punctuation between name and year. The full version of each parenthetical citation is listed alphabetically on the references page. For example: (Simon 2011) Simon is the author last name, and 2011 is the year.
  • You will need a citation directly after every sentence (or group of sentences if you're using the same source for multiple consecutive sentences) containing information you didn't think of yourself. These include: paraphrases, facts, statistics, quotes, and examples.

Step 2 Gather information.

  • If using a book, write down all pertinent information found on the copyright page, including the name of the publisher and the city and year of publication.
  • For other sources, look for this information near the title of the piece you’re looking at. Publication date is often at the bottom of webpages.

Step 3 Use Notes and Bibliography if instructed.

  • Title your references page “Bibliography” centered at the top of the page. Leave 2 blank lines between this title and the first entry, and one blank line between entries.
  • Notes and Bibliography style uses footnotes for page endings and endnotes for chapter endings. The bibliography page will be an alphabetized list of all sources in hanging indent.
  • An example format for a book is as follows: Last name, First name. Book Title . City: Publisher, Year.
  • An example format for a chapter in a print scholarly journal is as follows: Author last name, first name. "Title of Chapter or Article." Book or journal Title Issue Number (Year): Page number range. (For an online scholarly journal article, tack on the following at the end: Date accessed. URL address.)
  • When there is no known author, the entry should begin with the title of the document, whether it's a webpage, chapter, article, and so on.
  • When there are multiple authors, the first listed author appears last name, first name, so that the citation is alphabetized by this author's last name. Subsequent authors are listed by first name, like this: Alcott, Louisa May, Charles Dickens, and Elizabeth Gaskell.
  • Always end a citation with a period.

Step 4 Use Author Date if instructed.

  • When using Author Date style, title your references page “References” centered at the top of the page. Leave 2 blank lines between this title and the first entry, and 1 blank line between entries.
  • Author Date style bibliographies should be organized alphabetically by last name (or by title if no author) in hanging indent.
  • An example format for a book is as follows: Last name, first name. Year. Book Title . City Published: Publisher.
  • An example format for a chapter in a print scholarly journal is as follows: Author last name, first name. Year. "Title of Chapter or Article." Book or journal title issue number: page numbers. (for an online scholarly journal article tack this onto the end: Date accessed. URL address.)
  • An example format for a website is as follows: Name of Website. Year. "Page Title." Date last modified. Date accessed. URL address.

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.

How to Use In-Text Citations in MLA

An in-text citation in MLA includes the author's last name and the relevant page number:

<https://www.scribendi.com/academy/articles/how_to_cite_a_website.en.html>

How Do You Cite a Tweet in MLA ?

MLA uses the full text of a short Tweet (under 140 characters) as its title. Longer Tweets can be shortened using ellipses. 

MLA Tweet references should be formatted as follows:

@twitterhandle (Author Name). "Text of Tweet." Twitter, Date Month, Year, time of

publication, URL.

How to  Cite a Paraphrase in MLA

You can cite a paraphrase in MLA exactly the same way as you would cite a direct quotation. 

Make sure to include the author's name (either in the text or in the parenthetical citation) and the relevant page number.

How to Use In-Text Citations in APA

(Author, 2021, p. 123)

How to Cite a Website in APA

How to Cite a Paraphrase

How to Cite a Paraphrase in APA

Learning how to cite a website, how to cite a book, and how to cite a paraphrase can also help you avoid plagiarism —an academic offense with serious consequences for your education or professional reputation.

How to Write a Reference List (or Bibliography) For an Essay

An essay without a reference list is like a house without foundations – weak and unsupported!

After all, the reference list is ‘proof’ that the books and journals you referred to in your essay do exist. In turn, this makes your essay seem more credible.

But a reference list will only enhance your essay if it is accurate . That said, let’s explore how to write a clear and accurate reference list for an essay.

How to label your list of references

Firstly, make sure you know what to call the list of references at the end of your essay. The most common name for this list is a ‘reference list’. But some referencing styles call it a ‘bibliography’ or even a ‘works cited’ list. Also, it’s possible to have a ‘reference list’ and a ‘bibliography’ in the same essay.

What’s the difference between a reference list and a bibliography?

Generally speaking, a ‘reference list’ includes a list of all the sources that were cited in the essay – nothing more and nothing less. A bibliography, on the other hand, includes works that were consulted but not specifically cited in the essay. This is the traditional meaning of the term bibliography, at least.

But, in OSCOLA style, the ‘bibliography’ functions more like a ‘reference list’.

Confused? Don’t worry! This table will show you how to label the list of references according to your chosen referencing style.

Referencing styleHow to label the refs at the end of the essayDescriptionAPA

General rules to follow

Once you know how to label your list of references, you can start putting the list together. Here are some general rules that apply to all referencing styles:

  • Start your list of references on a new page – it looks a lot neater!
  • Get the placement right – references usually come at the end of the essay but before the appendix (if applicable).
  • Alphabetical order – the references should be arranged in alphabetical order (by surname).
  • Remove hyperlinks – that way, your reference list will look neat and tidy when it’s viewed on-screen.
  • Don’t change Americanisms – References should be written in their original form. So, if you’re citing the ‘Journal of Behavior Studies’ , don’t be tempted to change this to the ‘Journal of Behaviour Studies’ .
  • Word count – Remember that the reference list does not contribute to the total word count, so remember to deduct these words when you calculate the final word count.

When looking for sources, you might have noticed that some publications offer ‘suggested citations’. It can be helpful to copy and paste these suggested citations, but you will probably need to make some changes to ensure the citation is compliant with your referencing style. That said, let’s take a look at each referencing style in a bit more depth.

How to write a reference list in APA style

Key points to remember:

  • As a minimum, the reference should contain the author’s name , the date of the publication, the title , and the source (I.e. where it came from).
  • Additional information is also required for journals, such as the page number(s), the volume number and the issue number (see example).
  • The doi should be provided at the end of the reference (if applicable).
  • All lines except the first line should be indented – this is called a hanging indent. (Word: Paragraph>Special>Hanging).
  • Remember to put a full stop at the end of each reference.

For further guidance, check out APA Seventh Edition ! This resource is great as it provides plenty of examples.

How to write a bibliography in OSCOLA

At the end of your essay, you should report a ‘Table of Cases’ a ‘Table of Legislation’, and finally, a ‘Bibliography’. In OSCOLA, the bibliography should include all secondary sources that were cited in the essay.

The secondary sources are listed in a very similar way to the footnotes except that the author’s name is inverted (surname, first initial).

If there are any unattributed works, these should begin with ——.

You’ll notice that OSCOLA is a pretty minimalist referencing style. This means it’s quite easy to get the hang of. You can find full and detailed guidance in this OSCOLA referencing handbook .

How to write a reference list in Harvard style

There is no official manual for Harvard style like there is for APA and Chicago. Rather, universities adopt their own versions of Harvard style. So, if your faculty uses Harvard style, get a hold of your university’s referencing guide to check the requirements.

  • Generally speaking, though, a Harvard-style reference list is similar to an APA-style reference list, in that you must provide the author’s name, date of publication, title, and source. Similarly, book titles and journal titles should be italicised.
  • Unlike APA, there is no need to add a hanging indent.
  • Finally, when citing books, you should provide both the publisher’s name and location (Publisher Location: Publisher Name).

This Harvard referencing guide from The University of East Anglia is comprehensive yet easy to understand – definitely one of the best guides out there!

ASA reference list guidance

  • ASA is fairly similar to APA but notice the differences in punctuation (see examples).
  • The reference list must be double-spaced.
  • You should include the author’s first name and surname (unless the first name was not included in the original publication).
  • Also, the first author’s name should be inverted (surname, first name) but any subsequent names should not be inverted (first name, surname).

Note how a colon is used to introduce the page numbers. This is one of the key differences between APA and ASA style. For more information, check out the ASA quick style guide .

MLA ‘works cited’ guidance

As mentioned, the works cited list is equivalent to a reference list, so it must list all the publications that were cited in the essay.

  • The references should be formatted with a hanging indent (like APA).
  • Uniquely, the date comes towards the end of the reference.
  • First and last names are required (inverted)
  • The publisher’s name is required but the location is not.

Want to know more? This MLA resource is highly recommended!

How to write a reference list in Chicago style (in-text references)

  • Like APA and MLA, the references should be indented (hanging)
  • The author’s first name and surname should be provided
  • For books, the publisher’s location and name are required.
  • Notice that commas are rarely used (except to separate the volume and issue number of a journal).
  • A doi should be provided after an electronic resource. If there is no doi, a URL is acceptable.

The Chicago Manual of Style is updated regularly so always use the latest guidance. Finally, if you are using the Chicago footnote style of referencing, check out the bibliography guidance here .

Is the reference list really that important?

In a word, yes!

Imagine, for a moment, that you’ve just finished reading an essay…

Overall, it made some interesting points, but there were no references to back up the claims that were made. Would you think this was a good essay? Would you trust what the author had written? Or would you think it was lacking?

Once you see things from the reader’s perspective, the importance of the reference list suddenly becomes clear.

In essence, this special list boosts the credibility of your essay. So, don’t make it an after-thought.

Styles of referencing

Particular referencing styles are preferred by particular academic disciplines because they work better with the kind of texts that are most commonly used in that discipline. This page includes brief details of each style of referencing used by different departments at Reading. You should always check your course handbook to see which is their preferred style.  Remember that if you are studying modules in different departments or schools, they may each prefer a different referencing style.

Find out which style is used in your Department:

  • AMS referencing style Updated February 2023

Note that AMS style requires that journal names are abbreviated. The following is a source of suitable abbreviations: 

  • Chemical Abstracts Service Source Index (CASSI)

APA referencing is a variant on Harvard style. Many of the conventions are the same, with brief author-date citations in brackets in the body of the text and full citations in the reference list. It is usual to include a reference list only rather than a bibliography in APA style. Citations for websites are also slightly different, with no need to include an access or retrieval date unless the page content is likely to change over time.

Sources for more information

7th edition guidance

A new version of the APA style was published in 2019. Departments will gradually switch to this version - check your course handbook.

APA 7th edition differs significantly from APA 6th edition and other Harvard styles in that the place of publication is usually omitted from the reference.

Chicago style referencing offers two options for citations: 

So if you are asked to use Chicago style referencing, it is especially important to check which format your department wants you to use - notes and bibliography or author-date. You should be able to find more information in your course or module handbook . If you cannot find anything there, do ask your course tutor.

  • Chicago Manual of Style: Quick Guide Basic principles.

Also known as 'author-date' style. In Harvard style the in-text citation can be in brackets in the body of the text or in footnotes, and uses the author's surname and the date of publication, with the page number if it is a reference to a particular page. Full details are only listed in the bibliography or reference list.

Note that because Harvard is a 'style' rather than a system or set of rules, the preferred punctuation and formatting of the text may differ and your School/Department might have their own preferred version. Check your course handbook or the information in your subject guide for details of any local variations:

OSCOLA stands for Oxford Standard for the Citation of Legal Authorities. It is preferred by the School of Law at Reading, as it has rules for dealing with the kind of sources that law students will frequently use, including cases, statutes and command papers. In-text citations are placed in footnotes, with a formal set of abbreviations for key sources, e.g. AC for Appeal Cases. Punctuation is kept at a minimum, and there are specific rules for dealing with subsequent mentions.

In Vancouver referencing, which is a numeric referencing style, each source is given a number which corresponds to the order in which it appears in the text. If the same source is referred to again in the text, the same number is used. The reference list comprises a single numbered list of citations with full details. You may also include a separate bibliography, alphabetically ordered by author, which lists works that you have used as part of your research for your assignment but not cited in the text.

Use the DOI number for the source whenever one is available. DOI stands for "digital object identifier," a number specific to the article that can help others locate the source. In APA 7, format the DOI as a web address. Active hyperlinks for DOIs and URLs should be used for documents meant for screen reading.

If an article does not have a DOI and you retrieved it from a common academic research database through the university library, there is no need to include any additional electronic retrieval information. The reference list entry looks like the entry for a print copy of the article. (This format differs from APA 6 guidelines that recommended including the URL of a journal's homepage when the DOI was not available.) Note that APA 7 has additional guidance on reference list entries for articles found only in specific databases or archives such as Cochrane Database of Systematic Reviews, UpToDate, ProQuest Dissertations and Theses Global, and university archives. See APA 7, Section 9.30 for more information.

As a change from APA 6 to APA 7, it is no longer necessary to include the ebook format in the title. However, if you listened to an audiobook and the content differs from the text version (e.g., abridged content) or your discussion highlights elements of the audiobook (e.g., narrator's performance), then note that it is an audiobook in the title element in brackets. For ebooks and online audiobooks, also include the DOI number (if available) or nondatabase URL but leave out the electronic retrieval element if the ebook was found in a common academic research database, as with journal articles. APA 7 allows for the shortening of long DOIs and URLs, as shown in this example. See APA 7, Section 9.36 for more information.

When a text has been republished as part of an anthology collection, after the author’s name include the date of the version that was read. At the end of the entry, place the date of the original publication inside parenthesis along with the note “original work published.” For in-text citations of republished work, use both dates in the parenthetical citation, original date first with a slash separating the years, as in this example: Freud (1923/1961). For more information on reprinted or republished works, see APA 7, Sections 9.40-9.41.

Classroom Resources

Citing classroom resources.

If you need to cite content found in your online classroom, use the author (if there is one listed), the year of publication (if available), the title of the document, and the main URL of Walden classrooms. For example, you are citing study notes titled "Health Effects of Exposure to Forest Fires," but you do not know the author's name, your reference entry will look like this:

Health effects of exposure to forest fires [Lecture notes]. (2005). Walden University Canvas. https://waldenu.instructure.com

If you do know the author of the document, your reference will look like this:

Smith, A. (2005). Health effects of exposure to forest fires [PowerPoint slides]. Walden University Canvas. https://waldenu.instructure.com  

A few notes on citing course materials:

  • [Lecture notes]
  • [Course handout]
  • [Study notes]
  • It can be difficult to determine authorship of classroom documents. If an author is listed on the document, use that. If the resource is clearly a product of Walden (such as the course-based videos), use Walden University as the author. If you are unsure or if no author is indicated, place the title in the author spot, as above.
  • If you cannot determine a date of publication, you can use n.d. (for "no date") in place of the year.

Note:  The web location for Walden course materials is not directly retrievable without a password, and therefore, following APA guidelines, use the main URL for the class sites: https://class.waldenu.edu.

Merriam-Webster. (n.d.). Leadership. In Merriam-Webster.com dictionary . Retrieved May 28, 2020, from https://www.merriam-webster.com/dictionary/leadership

When constructing a reference for an entry in a dictionary or other reference work that has no byline (i.e., no named individual authors), use the name of the group—the institution, company, or organization—as author (e.g., Merriam Webster, American Psychological Association, etc.). The name of the entry goes in the title position, followed by "In" and the italicized name of the reference work (e.g., Merriam-Webster.com dictionary , APA dictionary of psychology ). In this instance, APA 7 recommends including a retrieval date as well for this online source since the contents of the page change over time. End the reference entry with the specific URL for the defined word.

Use this format for online videos such as Walden videos in classrooms. Most of our classroom videos are produced by Walden University, which will be listed as the author in your reference and citation. Note: Some examples of audiovisual materials in the APA manual show the word “Producer” in parentheses after the producer/author area. In consultation with the editors of the APA manual, we have determined that parenthetical is not necessary for the videos in our courses. The manual itself is unclear on the matter, however, so either approach should be accepted. Note that the speaker in the video does not appear in the reference list entry, but you may want to mention that person in your text. For instance, if you are viewing a video where Tobias Ball is the speaker, you might write the following: Tobias Ball stated that APA guidelines ensure a consistent presentation of information in student papers (Walden University, 2013). For more information on citing the speaker in a video, see our page on Common Citation Errors .

Technical and research reports by governmental agencies and other research institutions usually follow a different publication process than scholarly, peer-reviewed journals. However, they present original research and are often useful for research papers. Sometimes, researchers refer to these types of reports as gray literature , and white papers are a type of this literature. See APA 7, Section 10.4 for more information.

Reference list entires for TED Talks follow the usual guidelines for multimedia content found online. There are two common places to find TED talks online, with slightly different reference list entry formats for each.

TED Talk on the TED website

If you find the TED Talk on the TED website, follow the format for an online video on an organizational website:

Owusu-Kesse, K. (2020, June). 5 needs that any COVID-19 response should meet [Video]. TED Conferences. https://www.ted.com/talks/kwame_owusu_kesse_5_needs_that_any_covid_19_response_should_meet

The speaker is the author in the reference list entry if the video is posted on the TED website. For citations, use the speaker's surname.

TED Talk on YouTube

If you find the TED Talk on YouTube or another streaming video website, follow the usual format for streaming video sites:

TED. (2021, February 5). The shadow pandemic of domestic violence during COVID-19 | Kemi DaSilvalbru [Video]. YouTube. https://www.youtube.com/watch?v=PGdID_ICFII

TED is the author in the reference list entry if the video is posted on YouTube since it is the channel on which the video is posted. For citations, use TED as the author.

Walden University Course Catalog

To include the Walden course catalog in your reference list, use this format:

Walden University. (2020). 2019-2020 Walden University catalog . https://catalog.waldenu.edu/index.php

If you cite from a specific portion of the catalog in your paper, indicate the appropriate section and paragraph number in your text:

...which reflects the commitment to social change expressed in Walden University's mission statement (Walden University, 2020, Vision, Mission, and Goals section, para. 2).

And in the reference list:

Walden University. (2020). Vision, mission, and goals. In 2019-2020 Walden University catalog. https://catalog.waldenu.edu/content.php?catoid=172&navoid=59420&hl=vision&returnto=search

Vartan, S. (2018, January 30). Why vacations matter for your health . CNN. https://www.cnn.com/travel/article/why-vacations-matter/index.html

For webpages on the open web, include the author, date, webpage title, organization/site name, and URL. (There is a slight variation for online versions of print newspapers or magazines. For those sources, follow the models in the previous sections of this page.)

American Federation of Teachers. (n.d.). Community schools . http://www.aft.org/issues/schoolreform/commschools/index.cfm

If there is no specified author, then use the organization’s name as the author. In such a case, there is no need to repeat the organization's name after the title.

In APA 7, active hyperlinks for DOIs and URLs should be used for documents meant for screen reading. Present these hyperlinks in blue and underlined text (the default formatting in Microsoft Word), although plain black text is also acceptable. Be consistent in your formatting choice for DOIs and URLs throughout your reference list.

Writing Research Papers

  • What Types of References Are Appropriate?

When writing a research paper, there are many different types of sources that you might consider citing.  Which are appropriate?  Which are less appropriate?  Here we discuss the different types of sources that you may wish to use when working on a research paper.   

Please note that the following represents a general set of recommended guidelines that is not specific to any class and does not represent department policy.  The types of allowable sources may vary by course and instructor.

Highly appropriate: peer-reviewed journal articles

In general, you should primarily cite peer-reviewed journal articles in your research papers.  Peer-reviewed journal articles are research papers that have been accepted for publication after having undergone a rigorous editorial review process.  During that review process, the article was carefully evaluated by at least one journal editor and a group of reviewers (usually scientists that are experts in the field or topic under investigation).  Often the article underwent revisions before it was judged to be satisfactory for publication. 

Most articles submitted to high quality journals are not accepted for publication.  As such, research that is successfully published in a respected peer-reviewed journal is generally regarded as higher quality than research that is not published or is published elsewhere, such as in a book, magazine, or on a website.  However, just because a study was published in a peer-reviewed journal does not mean that it is free from error or that its conclusions are correct.  Accordingly, it is important to critically read and carefully evaluate all sources, including peer-reviewed journal articles.

Tips for finding and using peer-reviewed journal articles:

  • Many databases, such as PsycINFO, can be set to only search for peer-reviewed journal articles. Other search engines, such as Google Scholar, typically include both peer-reviewed and not peer-reviewed articles in search results, and thus should be used with greater caution. 
  • Even though a peer-reviewed journal article is, by definition, a source that has been carefully vetted through an editorial process, it should still be critically evaluated by the reader. 

Potentially appropriate: books, encyclopedias, and other scholarly works

Another potential source that you might use when writing a research paper is a book, encyclopedia, or an official online source (such as demographic data drawn from a government website).  When relying on such sources, it is important to carefully consider its accuracy and trustworthiness.  For example, books vary in quality; most have not undergone any form of review process other than basic copyediting.  In many cases, a book’s content is little more than the author’s informed or uninformed opinion. 

However, there are books that have been edited prior to publication, as is the case with many reputable encyclopedias; also, many books from academic publishers are comprised of multiple chapters, each written by one or more researchers, with the entire volume carefully reviewed by one or more editors.  In those cases, the book has undergone a form of peer review, albeit often not as rigorous as that for a peer-reviewed journal article.

Tips for using books, encyclopedias, and other scholarly works:

  • When using books, encyclopedias, and other scholarly works (that is, works written or produced by researchers, official agencies, or corporations), it is important to very carefully evaluate the quality of that source.
  • If the source is an edited volume (in which case in the editor(s) will be listed on the cover), is published by a reputable source (such as Academic Press, MIT Press, and others), or is written by a major expert in the field (such as a researcher with a track record of peer-reviewed journal articles on the subject), then it is more likely to be trustworthy.
  • For online encyclopedias such as Wikipedia, an instructor may or may not consider that an acceptable source (by default, don’t assume that a non-peer reviewed source will be considered acceptable). It is best to ask the instructor for clarification. 1

Usually inappropriate: magazines, blogs, and websites  

Most research papers can be written using only peer-reviewed journal articles as sources.  However, for many topics it is possible to find a plethora of sources that have not been peer-reviewed but also discuss the topic.  These may include articles in popular magazines or postings in blogs, forums, and other websites.  In general, although these sources may be well-written and easy to understand, their scientific value is often not as high as that of peer-reviewed articles.  Exceptions include some magazine and newspaper articles that might be cited in a research paper to make a point about public awareness of a given topic, to illustrate beliefs and attitudes about a given topic among journalists, or to refer to a news event that is relevant to a given topic. 

Tips for using magazines, blogs, and websites:

  • Avoid such references if possible. You should primarily focus on peer-reviewed journal articles as sources for your research paper.  High quality research papers typically do not rely on non-academic and not peer-reviewed sources.
  • Refer to non-academic, not peer-reviewed sources sparingly, and if you do, be sure to carefully evaluate the accuracy and scientific merit of the source.

  • Place the section label “References” in bold at the top of the page (centered).
  • Order the references alphabetically .
  • Double-space all text.

Prevent plagiarism. Run a free check.

References are ordered alphabetically by the first author’s last name. If the author is unknown, order the reference entry by the first meaningful word of the title (ignoring articles: “the”, “a”, or “an”).

Word processors like Word or Google Docs and citation generators can usually order the reference list automatically. However, ordering becomes challenging when citing multiple works by the same author or works by authors with the same last name.

Our in-depth article on ordering references in APA Style explains what to do in these situations.

Only include references for sources cited in the body text (with an APA in-text citation ). Don’t include references for:

  • Sources that you only consulted;
  • Personal communications (e.g., emails or phone calls);
  • General mentions of websites or periodicals ;
  • Common knowledge .

For some student papers, it’s common to describe or evaluate the source in an annotation . These annotations are placed on a new line below the corresponding reference entry. The entire annotation is indented 0.5 inches.

If an annotation consists of multiple paragraphs, the first line of the second and any subsequent paragraphs is indented an additional 0.5 inches.
