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.

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.

In-text citations are brief references in the running text that direct readers to the reference entry at the end of the paper. You include them every time you quote or paraphrase someone else’s ideas or words to avoid plagiarism .

An APA in-text citation consists of the author’s last name and the year of publication (also known as the author-date system). If you’re citing a specific part of a source, you should also include a locator such as a page number or timestamp. For example: (Smith, 2020, p. 170) .

Parenthetical vs. narrative citation

The in-text citation can take two forms: parenthetical and narrative. Both types are generated automatically when citing a source with Scribbr’s APA Citation Generator.

• Parenthetical citation: According to new research … (Smith, 2020) .
• Narrative citation: Smith (2020) notes that …

Multiple authors and corporate authors

The in-text citation changes slightly when a source has multiple authors or an organization as an author. Pay attention to punctuation and the use of the ampersand (&) symbol.

Missing information

When the author, publication date or locator is unknown, take the steps outlined below.

APA references generally include information about the author , publication date , title , and source . Depending on the type of source, you may have to include extra information that helps your reader locate the source.

Reference examples

Citing a source starts with choosing the correct reference format. Use Scribbr’s Citation Example Generator to learn more about the format for the most common source types. Pay close attention to punctuation, capitalization, and italicization.

Generate APA citations for free

It is not uncommon for certain information to be unknown or missing, especially with sources found online. In these cases, the reference is slightly adjusted.

On the first line of the page, write the section label “References” (in bold and centered). On the second line, start listing your references in alphabetical order .

Apply these formatting guidelines to the APA reference page:

• Double spacing (within and between references)
• Hanging indent of ½ inch
• Legible font (e.g. Times New Roman 12 or Arial 11)
• Page number in the top right header

Which sources to include

On the reference page, you only include sources that you have cited in the text (with an in-text citation ). You should not include references to personal communications that your reader can’t access (e.g. emails, phone conversations or private online material).

Scribbr Citation Checker New

The AI-powered Citation Checker helps you avoid common mistakes such as:

• Missing commas and periods
• Incorrect usage of “et al.”
• Ampersands (&) in narrative citations
• Missing reference entries

When no individual author name is listed, but the source can clearly be attributed to a specific organization—e.g., a press release by a charity, a report by an agency, or a page from a company’s website—use the organization’s name as the author in the reference entry and APA in-text citations .

When no author at all can be determined—e.g. a collaboratively edited wiki or an online article published anonymously—use the title in place of the author. In the in-text citation, put the title in quotation marks if it appears in plain text in the reference list, and in italics if it appears in italics in the reference list. Shorten it if necessary.

When you quote or paraphrase a specific passage from a source, you need to indicate the location of the passage in your APA in-text citation . If there are no page numbers (e.g. when citing a website ) but the text is long, you can instead use section headings, paragraph numbers, or a combination of the two:

(Caulfield, 2019, Linking section, para. 1).

Section headings can be shortened if necessary. Kindle location numbers should not be used in ebook citations , as they are unreliable.

If you are referring to the source as a whole, it’s not necessary to include a page number or other marker.

The abbreviation “ et al. ” (meaning “and others”) is used to shorten APA in-text citations with three or more authors . Here’s how it works:

Only include the first author’s last name, followed by “et al.”, a comma and the year of publication, for example (Taylor et al., 2018).

APA Style usually does not require an access date. You never need to include one when citing journal articles , e-books , or other stable online sources.

However, if you are citing a website or online article that’s designed to change over time, it’s a good idea to include an access date. In this case, write it in the following format at the end of the reference: Retrieved October 19, 2020, from https://www.uva.nl/en/about-the-uva/about-the-university/about-the-university.html

Referencing sources

Tools and resources, a quick guide to working with sources.

Working with sources is an important skill that you’ll need throughout your academic career.

It includes knowing how to find relevant sources, assessing their authority and credibility, and understanding how to integrate sources into your work with proper referencing.

This quick guide will help you get started!

Finding relevant sources

Sources commonly used in academic writing include academic journals, scholarly books, websites, newspapers, and encyclopedias. There are three main places to look for such sources:

• Research databases: Databases can be general or subject-specific. To get started, check out this list of databases by academic discipline . Another good starting point is Google Scholar .
• Your institution’s library: Use your library’s database to narrow down your search using keywords to find relevant articles, books, and newspapers matching your topic.
• Other online resources: Consult popular online sources like websites, blogs, or Wikipedia to find background information. Be sure to carefully evaluate the credibility of those online sources.

When using academic databases or search engines, you can use Boolean operators to refine your results.

Generate Harvard, APA, MLA, and Chicago style references in seconds

Get started

In academic writing, your sources should be credible, up to date, and relevant to your research topic. Useful approaches to evaluating sources include the CRAAP test and lateral reading.

CRAAP is an abbreviation that reminds you of a set of questions to ask yourself when evaluating information.

• Currency: Does the source reflect recent research?
• Relevance: Is the source related to your research topic?
• Authority: Is it a respected publication? Is the author an expert in their field?
• Accuracy: Does the source support its arguments and conclusions with evidence?
• Purpose: What is the author’s intention?

Lateral reading

Lateral reading means comparing your source to other sources. This allows you to:

• Verify evidence
• Contextualize information
• Find potential weaknesses

If a source is using methods or drawing conclusions that are incompatible with other research in its field, it may not be reliable.

Integrating sources into your work

Once you have found information that you want to include in your paper, signal phrases can help you to introduce it. Here are a few examples:

Following the signal phrase, you can choose to quote, paraphrase or summarize the source.

• Quoting : This means including the exact words of another source in your paper. The quoted text must be enclosed in quotation marks or (for longer quotes) presented as a block quote . Quote a source when the meaning is difficult to convey in different words or when you want to analyze the language itself.
• Paraphrasing: This means putting another person’s ideas into your own words. It allows you to integrate sources more smoothly into your text, maintaining a consistent voice. It also shows that you have understood the meaning of the source.
• Summarizing : This means giving an overview of the essential points of a source. Summaries should be much shorter than the original text. You should describe the key points in your own words and not quote from the original text.

Whenever you quote, paraphrase, or summarize a source, you must include a citation crediting the original author.

Referencing your sources is important because it:

• Allows you to avoid plagiarism
• Establishes the credentials of your sources
• Backs up your arguments with evidence
• Allows your reader to verify the legitimacy of your conclusions

The most common citation styles in the UK are APA, MLA, Harvard, Vancouver, MHRA, and Oscola. Each citation style has specific rules for formatting citations.

Scribbr’s free Reference Generator can generate perfect references and in-text citations in both APA and MLA styles. More citation styles will be available soon!
