Citing Sources: What are citations and why should I use them?

What is a citation.

Citations are a way of giving credit when certain material in your work came from another source. It also gives your readers the information necessary to find that source again-- it provides an important roadmap to your research process. Whenever you use sources such as books, journals or websites in your research, you must give credit to the original author by citing the source. 

Why do researchers cite?

Scholarship is a conversation  and scholars use citations not only to  give credit  to original creators and thinkers, but also to  add strength and authority  to their own work.  By citing their sources, scholars are  placing their work in a specific context  to show where they “fit” within the larger conversation.  Citations are also a great way to  leave a trail  intended to help others who may want to explore the conversation or use the sources in their own work.

In short, citations

(1) give credit

(2) add strength and authority to your work

(3) place your work in a specific context

(4) leave a trail for other scholars

"Good citations should reveal your sources, not conceal them. They should honeslty reflect the research you conducted." (Lipson 4)

What does a citation look like?

Different subject disciplines call for citation information to be written in very specific order, capitalization, and punctuation. There are therefore many different style formats. Three popular citation formats are MLA Style (for humanities articles) and APA or Chicago (for social sciences articles).

MLA style (print journal article):  

Whisenant, Warren A. "How Women Have Fared as Interscholastic Athletic Administrators Since the Passage of Title IX." Sex Roles Vol. 49.3 (2003): 179-182.

APA style (print journal article):

Whisenant, W. A. (2003) How Women Have Fared as Interscholastic Athletic Administrators Since the Passage of Title IX. Sex Roles , 49 (3), 179-182.

Chicago style (print journal article):

Whisenant, Warren A. "How Women Have Fared as Interscholastic Athletic Administrators Since the Passage of Title IX." Sex Roles 49, no. 3 (2003): 179-182.

No matter which style you use, all citations require the same basic information:

• Author or Creator
• Container (e.g., Journal or magazine, website, edited book)
• Date of creation or publication
• Publisher 

You are most likely to have easy access to all of your citation information when you find it in the first place. Take note of this information up front, and it will be much easier to cite it effectively later.

Tips for College Freshmen: From Social Life to Studying

Demure tiktok trend explained: what it is and why it’s going viral, college dorm checklist must-have things to take with you, how to develop a homework routine that works, what should you try before graduating senior bucket list, what is a citation.

When starting your first research work, you will find that citations play one of the central roles in building originality, credibility, and respect for both your work and intellectual property in general. Understanding what a citation is and how to use it effectively is fundamental for anyone engaging in scholarly writing.

Definition of a Citation

A citation is a formal reference to a source from which information or ideas have been drawn. I t is a way to credit the original author and to provide the readers with the necessary information to find the source themselves. Citations are vital in academic writing as they lend support and credibility to the writer’s own ideas and arguments, and they can be created via a free citation generator .

The Role of Citations in Scholarly Work

Creating citations is an inseparable part of academic writing, primarily serving as a guard against the unethical practice of plagiarizing. Plagiarism is the act of using another person’s work or ideas without giving them due credit, and it is considered a serious offense in the academic world. Citing sources demonstrates that writers respect the original author’s intellectual property and acknowledge their contribution to the field.

Moreover, citations illustrate that the writer has engaged in extensive research, adding depth and credibility to their work. They act as a roadmap, allowing readers to follow the trail of research and thought processes that led to the conclusions drawn in the paper. This transparency contributes to the audience’s understanding and allows them to verify the data and ideas presented, making sure the integrity and reliability of the scholarly discourse. Therefore, citations are essential to maintaining the honesty and trustworthiness of academic communication.

Types of Citations

Understanding the different types of citations is key to crafting well-researched and credible work. Each citation style, whether it’s APA, MLA, or Chicago, serves a specific purpose and follows distinct guidelines that build clarity and uniformity in academic communication. From in-text citations that subtly acknowledge sources within your narrative, to detailed bibliographies that offer a comprehensive overview of your research, mastering these various forms enhances the integrity and impact of your writing.

In-text Citations

In-text citations are integral to most academic writing formats. An example of an in-text citation in APA style is:

> (Smith, 2020).

This format briefly acknowledges the source within the text, typically featuring the author’s last name and the publication year. The purpose of in-text citations is to point the reader towards the more detailed reference list entry, allowing them to easily locate the full source details without cluttering the main text with extensive information.

Reference List Citations

Reference list citations are found at the end of an academic paper and provide comprehensive details about each source. For instance, a typical APA reference list entry might look like:

> Smith, J. (2020). Title of the Work . Publisher.

This format includes the author’s name, publication year, title of the work, and publisher details. The reference list ensures that every source mentioned in the in-text citations is accounted for, with sufficient information for the reader to find the original work.

Footnotes and Endnotes

Footnotes and endnotes serve as supplemental tools for citations or additional comments. An example of a footnote in Chicago style might appear as a superscript number within the text, with the corresponding note at the bottom of the page:

> ¹Smith, Title of the Work , 45.

Footnotes are found at the bottom of the page where the reference is made, while endnotes appear collectively at the end of the chapter or document. They can include full citation details or additional insights related to the content, providing further depth and context to the main text.

Citation Styles and Formats

Common Issues and Mistakes in Citation

In the world of academic writing, navigating the intricacies of citation can often be challenging, and it’s all too easy to stumble into common pitfalls. Incorrect citation format is a frequent error, where writers might mix up the requirements of different citation styles, such as confusing APA with MLA. This can lead to confusion and misinterpretation of the source material. Another common issue is missing information in citations, like omitting the publication date or the publisher’s name. This lack of detail can make it difficult for readers to locate the original sources, thereby affecting the paper’s reliability.

Inconsistency in citation styles throughout a document is another area where writers often err. For instance, using APA style in one section and then inadvertently switching to Chicago style in another can create a disjointed reading experience. Such inconsistencies not only disrupt the flow of your writing but also question its scholarly rigor . To maintain the integrity and credibility of your work, it is crucial to be thorough and consistent in your citation practices, carefully adhering to the rules of the chosen citation style. Remember, in the realm of academic writing, precision, and attention to detail in citations are as important as the content itself.

Citations are more than just formalities. They are a testament to a writer’s integrity, attention to detail, and engagement with the scholarly community. Proper citation practices honor the originality of ideas while building a reliable and verifiable body of knowledge. As such, mastering the art of citation is a key skill in academic writing.

What information should be included in a citation?

A citation should typically include the author’s name, the title of the work, publication date, and other relevant details like the publisher’s name, journal title, volume and issue numbers, and page numbers. For digital sources, URLs or DOIs (Digital Object Identifiers) are also essential.

Can I use online citation generators?

Yes, online citation generators can be used and are quite helpful in automating the citation process. However, it’s important to double-check the generated citations for accuracy, as these tools can sometimes make errors or be outdated in terms of citation style guidelines.

What are the consequences of not citing sources?

Not citing sources can lead to accusations of plagiarism, which is a serious academic offense. It can result in various consequences ranging from loss of credibility and academic penalties to legal repercussions. Proper citation is essential to maintain the integrity and reliability of your work.

Is there a difference between citing books and websites?

Yes, there is a difference in citing books and websites. Book citations typically require the author’s name, book title, publisher, and publication year. Website citations, however, often include the author’s name, title of the web page or article, the name of the website, the publication date, and the URL or DOI.

When do I need to use in-text citations?

In-text citations are used whenever you quote, paraphrase, or refer to information from a source in the body of your text. These citations provide a brief acknowledgment of the source, typically including the author’s last name and publication year, which correspond to a more detailed entry in the reference list or bibliography.

If you have questions after consulting this guide about how to cite, please contact your advisor/professor or the writing and communication center .

Why citing is important

It's important to cite sources you used in your research for several reasons:

• To show your reader you've done proper research by listing sources you used to get your information
• To be a responsible scholar by giving credit to other researchers and acknowledging their ideas
• To avoid plagiarism by quoting words and ideas used by other authors
• To allow your reader to track down the sources you used by citing them accurately in your paper by way of footnotes, a bibliography or reference list

About citations

Citing a source means that you show, within the body of your text, that you took words, ideas, figures, images, etc. from another place.

Citations are a short way to uniquely identify a published work (e.g. book, article, chapter, web site).  They are found in bibliographies and reference lists and are also collected in article and book databases.

Citations consist of standard elements, and contain all the information necessary to identify and track down publications, including:

• author name(s)
• titles of books, articles, and journals
• date of publication
• page numbers
• volume and issue numbers (for articles)

Citations may look different, depending on what is being cited and which style was used to create them. Choose an appropriate style guide for your needs.  Here is an example of an article citation using four different citation styles.  Notice the common elements as mentioned above:

Author - R. Langer

Article Title - New Methods of Drug Delivery

Source Title - Science

Volume and issue - Vol 249, issue 4976

Publication Date - 1990

Page numbers - 1527-1533

American Chemical Society (ACS) style:

Langer, R. New Methods of Drug Delivery. Science 1990 , 249 , 1527-1533.

IEEE Style:

R. Langer, " New Methods of Drug Delivery," Science , vol. 249 , pp. 1527-1533 , SEP 28, 1990 .

American Psychological Association   (APA) style:

Langer, R. (1990) . New methods of drug delivery. Science , 249 (4976), 1527-1533.

Modern Language Association (MLA) style:

Langer, R. " New Methods of Drug Delivery." Science 249.4976 (1990) : 1527-33.

What to cite

You must cite:

• Facts, figures, ideas, or other information that is not common knowledge

Publications that must be cited include:  books, book chapters, articles, web pages, theses, etc.

Another person's exact words should be quoted and cited to show proper credit 

When in doubt, be safe and cite your source!

Avoiding plagiarism

Plagiarism occurs when you borrow another's words (or ideas) and do not acknowledge that you have done so. In this culture, we consider our words and ideas intellectual property; like a car or any other possession, we believe our words belong to us and cannot be used without our permission.

Plagiarism is a very serious offense. If it is found that you have plagiarized -- deliberately or inadvertently -- you may face serious consequences. In some instances, plagiarism has meant that students have had to leave the institutions where they were studying.

The best way to avoid plagiarism is to cite your sources - both within the body of your paper and in a bibliography of sources you used at the end of your paper.

Why Are Citations Important?

What Does a Citation Look Like?

A citation is typically found in two places:, in-text citations.

Reference Lists/Bibliographies

Authors use in-text citations after they have paraphrased, summarized, quoted or otherwise used another author’s work. Examples of in-text citations include parentheses, footnotes or endnotes.

Reference Lists

A reference list includes information on all of the sources an author used. It can also be called a bibliography or works cited. Each item in the list includes information such as title, author and publication date. A reference list is usually listed at the end of a paper with the exception of footnotes which are at the bottom of each page.

Reading a Citation

Knowing how to read a citation in a reference list or bibliography will help you identify different types of sources that an author used in their research. You can use a reference list from another researcher to find related sources on your topic, or to find counterpoints to your research. Let’s look at citations for three common types of sources:

Reading Citations: Article Citations

A citation for an article can include:.

Why is this important?

The journal title is often what is listed in library catalogs.

How do you know if it is an article?

The presence of two titles (article and journal) are the biggest clue that this is an article. Volume Number and Issue Number are also big clues as books will not have those pieces in a citation.

Reading Citations: Book Citations

A citation for a book can include:.

Year, edition, format, and publisher help distinguish between versions.

How do you know if it is a book?

Reading Citations: Website Citations

A citation for a website can include:.

To find and verify a website, you need to know the URL. Since websites change frequently, knowing the date accessed is similar to knowing a publication date.

How do you know if it is a website?

The date accessed and the presence of a URL are the biggest clues that you are looking at a citation for a website.

Citation Styles

Different disciplines cite in different ways which means that there are many different citation styles.

Your professor or department will tell you what style to use.

Style guides, manuals and handbooks are available both in print and online.

Basic Principles of Citation

APA Style uses the author–date citation system , in which a brief in-text citation directs readers to a full reference list entry. The in-text citation appears within the body of the paper (or in a table, figure, footnote, or appendix) and briefly identifies the cited work by its author and date of publication. This enables readers to locate the corresponding entry in the alphabetical reference list at the end of the paper.

Each work cited must appear in the reference list, and each work in the reference list must be cited in the text (or in a table, figure, footnote, or appendix).

Both paraphrases and quotations require citations.

The following are guidelines to follow when writing in-text citations:

• Ensure that the spelling of author names and the publication dates in reference list entries match those in the corresponding in-text citations.
• Cite only works that you have read and ideas that you have incorporated into your writing. The works you cite may provide key background information, support or dispute your thesis, or offer critical definitions and data.
• Readers may find a long string of citations difficult to understand, especially if they are using assistive technology such as a screen reader; therefore, include only those citations needed to support your immediate point.
• Cite primary sources when possible, and cite secondary sources sparingly.
• Cite sources to document all facts and figures that you mention that are not common knowledge.
• To cite a specific part of a source , provide an author–date citation for the work plus information about the specific part.
• Even when sources cannot be retrieved (e.g., because they are personal communications ), still credit them in the text (however, avoid using online sources that are no longer recoverable).

Basic principles of citation are covered in the seventh edition APA Style manuals in the Publication Manual Sections 8.1 to 8.36 and the Concise Guide Sections 8.1 to 8.34

How to Cite Sources

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

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

MLA Format Citation Examples

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

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

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

APA Format Citation Examples

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

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

Chicago Style Citation Examples

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

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

6 Interesting Citation Facts

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

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

1. There are Over 7,000 Different Citation Styles

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

2. Some Citation Styles are Named After People

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

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

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

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

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

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

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

6. Citation Styles are Always Changing

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

Why Citations Matter

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

They Give Credit to the Right People

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

They Provide Hard Evidence of Ideas

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

They Promote Originality and Prevent Plagiarism

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

They Create Better Researchers

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

When is the Right Time to Start Making Citations?

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

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

(Dickens 11).

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

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

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

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

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

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

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

What is a Citation?

A  citation  is a reference that allows you to acknowledge the sources* you use in a formal academic paper, and enables a reader to locate those sources through the key information it provides.

Citations are placed both in the text and in an organized list at the end of the text. The format of the citations can vary depending on the citation style that is used. If a footnote or endnote system is used, citations can be self-contained without an organized list.

*Source material might come from books, journal articles, speeches, websites, on-line articles, films, government publications, legal proceedings, maps, and so on.

It is important to cite when borrowing the ideas and thoughts of others for several reasons.

Citing sources

• builds credibility in your work by showing you are not alone in your opinions;
• gives you a chance to show that you have thought about and investigated your topic;
• gives your reader the information he or she needs to verify your source or to find more information on the subject; and
• allows you to give credit where credit is due.

Not citing your sources is academically dishonest and may lead to charges of plagiarism.

In addition, citations are integral to scholarly literature. The scholarly literature on a topic is like a huge conversation that can include many experts from around the world and across the centuries. When an individual writer credits his sources, he ties his work to the larger scholarly discourse. Because citations identify intellectual links throughout scholarly literature, they can be helpful not only when writing but also when conducting research.

Citations enable you as a researcher to

• verify the facts and opinions set forth in a piece of writing;
• identify additional sources that may delve more deeply into a subject;
• distinguish the ideas of various experts regarding a specific topic;
• measure the influence of one thinker upon another; and
• trace the evolution of an idea as it passes from scholar to scholar, from culture to culture, and from era to era.

What are citations, and why are they important?

What is a citation.

A citation, also known as a reference, is a direct, specific description of a particular work. Each citation usually includes the date of creation or publication, the creator's name, and the title of the work.

Why use citations?

• It protects you against accidental plagiarism. When you give creators credit for their work through citation, you are not plagiarizing their ideas. 
• It creates authority for your ideas. If you use the work of experts to support your ideas, your arguments are stronger. 
• It gives your reader or audience an opportunity to learn more.

How do I use citations?

There are many different citation styles. Most citations have an in-text citation in the body of your writing and a list at the end of the document of all the citations. The most common for the scientific disciplines is APA. Social sciences and the humanities may use the Chicago Style or MLA. Your professor will tell you which to use. 

The Georgia Tech Library recommends the Purdue OWL online guide to citation styles. It is extensive and free for anyone to use. It can be found at Purdue OWL .

What is a Citation?

A citation identifies for the reader the original source for an idea, information, or image that is referred to in a work.

• In the body of a paper, the  in-text citation  acknowledges the source of information used.
• At the end of a paper, the citations are compiled on a  References  or  Works Cited  list. A basic citation includes the author, title, and publication information of the source. 

From:  Lemieux  Library,  University  of Seattle 

Why Should You Cite?

Quoting Are you quoting two or more consecutive words from a source? Then the original source should be cited and the words or phrase placed in quotes. 

Paraphrasing If an idea or information comes from another source,  even if you put it in your own words , you still need to credit the source.  General vs. Unfamiliar Knowledge You do not need to cite material which is accepted common knowledge. If in doubt whether your information is common knowledge or not, cite it. Formats We usually think of books and articles. However, if you use material from web sites, films, music, graphs, tables, etc. you'll also need to cite these as well.

Plagiarism is presenting the words or ideas of someone else as your own without proper acknowledgment of the source. When you work on a research paper and use supporting material from works by others, it's okay to quote people and use their ideas, but you do need to correctly credit them. Even when you summarize or paraphrase information found in books, articles, or Web pages, you must acknowledge the original author.

A citation , in college reading, writing, or speaking, is a reference to a source of information. The goal of all citations is to allow the audience (whether reading or listening) to identify and find the source of your information.  There are several different ways that information can be cited:

• In-text citation s are short notes that must be included with your text where the idea, data, or evidence from that source is used. In-text citations should match to a complete list of full citations, usually included as the last page of your paper.
• Verbal citations should be provided when you are giving a speech. You will need to mention the author and something about why the author is worthy of citing.
• Full citations provide all of the elements necessary for the reader to find the exact same source used by the writer. Full citations should be provided  for all the sources used or consulted in your research project. This will usually be in a list at the end of your paper called either a Works Cited list or References page.  It may also be on a separate sheet for speeches.

There are a variety of different formats that can be used for citations - MLA and APA are the two most commonly used at CR, but many other specialized styles exist as well.  Consult your assignment handout or ask your instructor which citation format you will be required to use. 

All citation styles will require you to include important elements from your source so that the reader can find that exact same source. Some of these important elements are author, title, publisher, place of publication, date of publication. APA and MLA styles format the citation elements slightly differently. Select the tab at the top of this guide for the style you need to find instructions, examples, and a PDF handout for that citation style that you can print.

What Is A Citation?

When to cite.

A citation is a reference to the source of information used in your research. Any time you directly quote, paraphrase or summarize the essential elements of someone else's idea in your work, an in-text citation should follow. An in-text citation is a brief notation within the text of your paper or presentation which refers the reader to a fuller notation, or end-of-paper citation , that provides all necessary details about that source of information. Direct quotations should be surrounded by quotations marks and are generally used when the idea you want to capture is best expressed by the source.  Paraphrasing and summarizing involve rewording an essential idea from someone else's work, usually to either condense the point or to make it better fit your writing style. You do not have to cite your own ideas, unless they have been published. And you do not have to cite  common knowledge , or information that most people in your audience would know without having to look it up.

In-Text Citations

In-text citations alert the reader to an idea from an outside source.  

Parenthetical Notes

In MLA and APA styles, in-text citations usually appear as parenthetical notes (sometimes called parenthetical documentation ). They are called parenthetical notes because brief information about the source, usually the author's name, year of publication, and page number, is enclosed in parentheses as follows:  

MLA style: (Smith 263)

APA style: (Smith, 2013, p. 263)  

Parenthetical notes are inserted into the text of the paper at the end of a sentence or paragraph:>

In MLA and APA styles, in-text citations are associated with end-of-paper citations that provide full details about an information source. Note: Different source types and situations require different information within the parentheses. Refer to a style guide for the style you are using for details.

Note Numbers

In Chicago and CSE styles, in-text citations usually appear as superscript numerals, or note numbers , as follows:

These note numbers are associated with full citations that can appear as footnotes (bottom of page), endnotes (end of chapter or paper), or lists of cited references at the end of the paper.  

End-of-Paper Citations

End-of-paper citations, as well as footnotes and endnotes, include  full details about a source of information.  Citations contain different pieces of identifying information about your source depending on what type of source it is. In academic research, your sources will most commonly be articles from scholarly journals, and the citation for an article typically includes:  

• article title
• publication information (journal title, date, volume, issue, pages, etc.)
• DOI (digital object identifier).
• URL of the information source itself
• URL of the journal that published the article

There are many other types of sources you might use, including books, book chapters, films, song lyrics, musical scores, interviews, e-mails, blog entries, art works, lectures, websites and more. To determine which details are required for a citation for a particular source type, find that source type within the style guide for the citation style you are using. At the end of your research paper, full citations should be listed in order according to the citation style you are using:

• In MLA style, this list is called a W orks Cited page.  
• In APA style, it is called a References page.
• In CSE style, it is called a C ited References page.
• And, in Chicago style, there may be both a Notes page and a Bibliography page. 

Citations  In Library Databases

When you search the library's databases for articles or e-books, the list of search results you see is actually a list of full citations. Instead of being formatted according to MLA, APA, CSE, or Chicago style, these citations are formatted according to the database vendor's style. It is up to you to take the source information you find in a library database (or elsewhere) and format it according to the citation style you are using.

What is a Citation?

A “ citation ” refers to the act of integrating ideas or words from another source into your speech or writing , along with adhering to the specific discourse conventions (or standardized ways of acknowledging sources) in a particular academic or professional field . “Citations” are required in academic and professional writing when writers summarize , paraphrase , or quote the words or ideas others. Writers may also cite known experts to enhance the authority of their arguments and observations.

In both academic and professional settings, the practice of citing sources—whether through quotations , paraphrasing , or summarizing —is a fundamental mark of professionalism. Being capable of citing sources correctly and critiquing the citations of others is a basic literacy in a knowledge economy.

Most generally, “citation” refers to the act of crediting a source of information . While “citation” is the formal term, there are several colloquial synonyms that people might use interchangeably, such as “ attribution ,” “reference,” or “mention.” In more casual or conversational settings, phrases like “backing up” one’s claim or providing “proof” might be used. When writers or speakers incorporate information from an external source, they might say they are “citing,” “ attributing ,” or “referencing” that source.

What Are The Three Major Ways of Citing Sources inside a Text?

While there are many different citation styles, as discussed below, there are only three major types of citations:

• In-text Citation (aka Parenthetical Citation)
• Numerical citation
• Note Citations

In-text Citation (aka Parenthetical Citation )

In-text Citation refers to the practice of placing bibliographical information in parentheses when sources/information are first introduced in a quote , paraphrase , or summary . The in-text citation is typically shorter and directs the reader to the full citation in the bibliography or reference list. In essence, all in-text citations are citations, but not all citations are in-text citations.

APA Example

When using APA style, writers place the author’s name, year, and page number (when available) in parentheses.

• “As of 2022, about 12,700 nuclear warheads are still estimated to be in use, of which more than 9,400 are in military stockpiles for use by missiles, aircraft, ships and submarines” (Eagle, 2022).

And then at the end of their text, they list all of the sources they cited in the text, providing all of the bibliographical information users need to track down the source and read it:

• Eagle, J. (2022, March 21). Animated chart: Nuclear warheads by country (1945-2022). Visual Capitalist .

Numerical Citation

Numerical Citation refers to when writers use numbers in brackets or superscript rather than parentheses to indicate to readers when they are quoting , paraphrasing , or summarizing :

IEEE Example

• “As of 2022, about 12,700 nuclear warheads are still estimated to be in use, of which more than 9,400 are in military stockpiles for use by missiles, aircraft, ships and submarines” [1]

Subsequently, in the reference list at the end of their text, writers provided the bibliographic information following the order of the citations in the text:

Chicago (Turabian) Example

• [1]J. Eagle, “Animated Chart: Nuclear Warheads by Country (1945-2022),” Visual Capitalist , Mar. 21, 2022. (accessed Jan. 03, 2023).

[ See Inclusive – Inclusive Language for a full-length example of Numerical Citations ]

Note Citation

Note Citations refers to when writers place citations numbers just as they do with numerical citations AND then provide all of the required bibliographical information in the text–as opposed to providing all that information at the end of the text in a list of references:

• “As of 2022, about 12,700 nuclear warheads are still estimated to be in use, of which more than  9,400  are in military stockpiles for use by missiles, aircraft, ships and submarines” J. Eagle, “Animated Chart: Nuclear Warheads by Country (1945-2022),” Visual Capitalist , Mar. 21, 2022. (accessed Jan. 03, 2023).

What Do All Citations Styles Have in Common?

Regardless of which citation style is used, attributions typically provide four types of bibliographical information :

• Name of Author(s)
• Title of source, whether it’s a book/article/website, etc
• Date of publication, if available
• Publisher information.

What Are the Most Popular Citation Styles?

Professional organizations (communities of practice) have unique ways of formatting citations. (See Wikipedia for a good listing of citation styles .)

Although style guides differ in regard to where the author’s name or publishing source is listed, they are all designed to ensure that proper credit is given to authors. As you know from your experience as a writer, developing insights and conducting original research is difficult and time consuming, so you can understand why people want to receive proper credit for their original ideas.

• MLA Handbook, 9th Edition Modern Language Association style is primarily used in the fields of English and foreign languages.
• Publication Manual of the APA: 7th Edition American Psychological Association’s style guide is used in psychology and education. Education and social science professors commonly ask students to follow the APA style for citing and documenting sources. APA differs from MLA in a number of ways, including the overall structure and format of the essay, but the major distinction between the two is APA’s use of the year of publication, rather than the page on which a particular quotation appears, for the in-text citation. APA requires in-text publication dates because of the particular importance of a study’s currency to research reports in the social sciences.
• Chicago Style is used in many social science fields.
• CSE (Council of Science Editors) is used by the scientific community
• IEEE (Institute of Electrical and Electronic Engineers) is used by the engineering community.

What Critical Perspectives Do Readers Use to Assess Your Citations?

Citation in speech and writing serves as a barometer of ethos , especially trustworthiness . When audiences are engaged in critical literacy practices , they are likely to question a source’s

When audiences check the archive and find that authors are making inconsistent quotations , they are likely to question the character or ethos of the author.

In other words, subject matter experts tend to be well versed in the ongoing conversations that characterize the works of other subject matter experts. Experienced researchers tend to engage in strategic searching of the archive . They engage in critical literacy practices , asking questions, such as

• What is the status of knowledge on the topic ?
• What is the ebb and flow of research on the topic –over time?
• What are the canonical texts ?
• Who are the pioneers? How has their work changed the conversation?
• What knowledge claims are currently being debated?

A citation is a formal reference to a published or unpublished source that you consulted and obtained information from while writing your research paper. It refers to a source of information that supports a factual statement, proposition, argument, or assertion or any quoted text obtained from a book, article, web site, or any other type of material . In-text citations are embedded within the body of your paper and use a shorthand notation style that refers to a complete description of the item at the end of the paper. Materials cited at the end of a paper may be listed under the heading References, Sources, Works Cited, or Bibliography. Rules on how to properly cite a source depends on the writing style manual your professor wants you to use for the class [e.g., APA, MLA, Chicago, Turabian, etc.]. Note that some disciplines have their own citation rules [e.g., law].

Citing Your Sources

Reasons for Citing Sources in Your Research Paper

English scientist, Sir Isaac Newton, once wrote, "If I have seen further, it is by standing on the shoulders of giants.”* Citations support learning how to "see further" through processes of intellectual discovery, critical thinking, and applying a deliberate method of navigating through the scholarly landscape by tracking how cited works are propagated by scholars over time and the subsequent ways this leads to the devarication of new knowledge.

Listed below are specific reasons why citing sources is an important part of doing good research.

• Shows the reader where to find more information . Citations help readers expand their understanding and knowledge about the issues being investigated. One of the most effective strategies for locating authoritative, relevant sources about a research problem is to review materials cited in studies published by other authors. In this way, the sources you cite help the reader identify where to go to examine the topic in more depth and detail.
• Increases your credibility as an author . Citations to the words, ideas, and arguments of scholars demonstrates that you have conducted a thorough review of the literature and, therefore, you are reporting your research results or proposing recommended courses of action from an informed and critically engaged perspective. Your citations offer evidence that you effectively contemplated, evaluated, and synthesized sources of information in relation to your conceptualization of the research problem.
• Illustrates the non-linear and contested nature of knowledge creation . The sources you cite show the reader how you characterized the dynamics of prior knowledge creation relevant to the research problem and how you managed to identify the contested relationships between problems and solutions proposed among scholars. Citations don't just list materials used in your study, they tell a story about how prior knowledge-making emerged from a constant state of creation, renewal, and transformation.
• Reinforces your arguments . Sources cited in your paper provide the evidence that readers need to determine that you properly addressed the “So What?” question. This refers to whether you considered the relevance and significance of the research problem, its implications applied to creating new knowledge, and its importance for improving practice. In this way, citations draw attention to and support the legitimacy and originality of your own ideas and assertions.
• Demonstrates that you "listened" to relevant conversations among scholars before joining in . Your citations tell the reader where you developed an understanding of the debates among scholars. They show how you educated yourself about ongoing conversations taking place within relevant communities of researchers before inserting your own ideas and arguments. In peer-reviewed scholarship, most of these conversations emerge within books, research reports, journal articles, and other cited works.
• Delineates alternative approaches to explaining the research problem . If you disagree with prior research assumptions or you believe that a topic has been understudied or you find that there is a gap in how scholars have understood a problem, your citations serve as the source materials from which to analyze and present an alternative viewpoint or to assert that a different course of action should be pursued. In short, the materials you cite serve as the means by which to argue persuasively against long-standing assumptions promulgated in prior studies.
• Helps the reader understand contextual aspects of your research . Cited sources help readers understand the specific circumstances, conditions, and settings of the problem being investigated and, by extension, how your arguments can be fully understood and assessed. Citations place your line of reasoning within a specific contextualized framework based on how others have studied the problem and how you interpreted their findings in support of your overall research objectives.
• Frames the development of concepts and ideas within the literature . No topic in the social and behavioral sciences rests in isolation from research that has taken place in the past. Your citations help the reader understand the growth and transformation of the theoretical assumptions, key concepts, and systematic inquiries that emerged prior to your engagement with the research problem.
• Underscores sources that were most important to you . Your citations represent a set of choices made about what you determined to be the most important sources for understanding the topic. They not only list what you discovered, but why it matters and how the materials you chose to cite fit within the broader context of your research design and arguments. As part of an overall assessment of the study’s validity and reliability , the choices you make also helps the reader determine what sources of research may have been excluded.
• Provides evidence of interdisciplinary thinking . An important principle of good research is to extend your review of the literature beyond the predominant disciplinary space where scholars have previously examined a topic. Citations provide evidence that you have integrated epistemological arguments, observations, and/or methodological strategies of other disciplines into your paper, thereby demonstrating that you understand the complex, interconnected nature of contemporary research topics.
• Forms the basis for bibliometric analysis of research . Bibliometric analysis is a quantitative method used, for example, to identify and predict emerging trends in research, document patterns of collaboration among scholars, explore the intellectual structure of a specific domain of research, map the development of research within and across disciplines, or identify gaps in knowledge within the literature. Bibliometric data can also be used to visually map relationships among published studies. Citations to books, journal articles, research reports, and other publications represent the raw data used in bibliometric research.
• Reveals possible adherence to the principles of citational justice. Citational justice refers to equity in the inclusion of sources published by authors who are members of marginalized or underrepresented groups that are often under-cited because of their background, community of origin, identity, or location. In so doing, this movement “challenges entrenched hierarchies and biases in knowledge production.” ** Within this context, the sources cited in your paper can help the reader obtain a more inclusive divergency of voices and perspectives about how a research problem can be understood and investigated.
• Supports critical thinking and independent learning . Evaluating the authenticity, reliability, validity, and originality of prior research is an act of interpretation and introspective reasoning applied to assessing whether a source of information will contribute to understanding the problem in ways that are persuasive and align with your overall research objectives. Reviewing and citing prior studies represents a deliberate act of critically scrutinizing each source as part of your overall assessment of how scholars have confronted the research problem.
• Honors the achievements of others . As Susan Blum recently noted, *** citations not only identify sources used, they acknowledge the achievements of scholars within the larger network of research about the topic. Citing sources is a normative act of professionalism within academe and a way to highlight and recognize the work of scholars who likely do not obtain any tangible benefits or monetary value from their research endeavors. Your citations help to validate the work of others.

Structure and Writing Style

Referencing your sources means systematically showing what information or ideas you acquired from another author’s work, and identifying where that information come from . You must cite research in order to do research, but at the same time, you must delineate what are your original thoughts and ideas and what are the thoughts and ideas of others. Citations help achieve this. Procedures used to cite sources vary among different fields of study. If not outlined in your course syllabus or writing assignment, always speak with your professor about what writing style for citing sources should be used for the class because it is important to fully understand the citation style to be used in your paper, and to apply it consistently. If your professor defers and tells you to "choose whatever you want, just be consistent," then choose the citation style you are most familiar with or that is appropriate to your major [e.g., use Chicago style if you are majoring in history; use APA if its an education course; use MLA if it is literature or a general writing course].

GENERAL GUIDELINES

1. Are there any reasons I should avoid referencing other people's work? No. If placed in the proper context, r eferencing other people's research is never an indication that your work is substandard or lacks originality. In fact, the opposite is true. If you write your paper without adequate references to previous studies, you are signaling to the reader that you are not familiar with the literature on the topic, thereby, undermining the validity of your study and your credibility as a researcher. Including references in academic writing is one of the most important ways to demonstrate your knowledge and understanding of how the research problem has been addressed. It is the intellectual packaging around which you present your thoughts, ideas, and arguments to the reader.

2. What should I do if I find out that my great idea has already been studied by another researcher? It can be frustrating to come up with what you believe is a great topic only to find that it's already been thoroughly studied. However, do not become frustrated by this. You can acknowledge the prior research by writing in the text of your paper [see also Smith, 2002], then citing the complete source in your list of references. Use the discovery of prior studies as an opportunity to demonstrate the significance of the problem being investigated and, if applicable, as a means of delineating your analysis from those of others [e.g., the prior study is ten years old and doesn't take into account new variables]. Strategies for responding to prior research can include: stating how your study updates previous understandings about the topic, offering a new or different perspective, applying a different or innovative method of gathering and interpreting data, and/or describing a new set of insights, guidelines, recommendations, best practices, or working solutions.

3. What should I do if I want to use an adapted version of someone else's work? You still must cite the original work. For example, you use a table of statistics from a journal article published in 1996 by author Smith, but you have altered or added new data to it. Reference the revised chart, such as, [adapted from Smith, 1996], then cite the original source in your list of references. You can also use other terms in order to specify the exact relationship between the original source and the version you have presented, such as, "based on data from Smith [1996]...," or "summarized from Smith [1996]...." Citing the original source helps the reader locate where the information was first presented and under what context it was used as well as to evaluate how effectively you applied it to your own research.

4. What should I do if several authors have published very similar information or ideas? You can indicate that the topic, idea, concept, or information can be found in the works of others by stating something similar to the following example: "Though many scholars have applied rational choice theory to understanding economic relations among nations [Smith, 1989; Jones, 1991; Johnson, 1994; Anderson, 2003; Smith, 2014], little attention has been given to applying the theory to examining the influence of non-governmental organizations in a globalized economy." If you only reference one author or only the most recent study, then your readers may assume that only one author has published on this topic, or more likely, they will conclude that you have not conducted a thorough review of the literature. Referencing all relevant authors of prior studies gives your readers a clear idea of the breadth of analysis you conducted in preparing to study the research problem. If there has been a significant number of prior studies on the topic [i.e., ten or more], describe the most comprehensive and recent works because they will presumably discuss and reference the older studies. However, note in your review of the literature that there has been significant scholarship devoted to the topic so the reader knows that you are aware of the numerous prior studies.

5. What if I find exactly what I want to say in the writing of another researcher? In the social sciences, the rationale in duplicating prior research is generally governed by the passage of time, changing circumstances or conditions, or the emergence of variables that necessitate new investigations . If someone else has recently conducted a thorough investigation of precisely the same research problem that you intend to study, then you likely will have to revise your topic, or at the very least, review this literature to identify something new to say about the problem. However, if it is someone else's particularly succinct expression, but it fits perfectly with what you are trying to say, then you can quote from the author directly, referencing the source. Identifying an author who has made the exact same point that you want to make can be an opportunity to validate, as well as reinforce the significance of, the research problem you are investigating. The key is to build on that idea in new and innovative ways. If you are not sure how to do this, consult with a librarian .

6. Should I cite a source even if it was published long ago? Any source used in writing your paper should be cited, regardless of when it was written. However, in building a case for understanding prior research about your topic, it is generally true that you should focus on citing more recently published studies because they presumably have built upon the research of older studies. When referencing prior studies, use the research problem as your guide when considering what to cite. If a study from forty years ago investigated the same topic, it probably should be examined and considered in your list of references because the research may have been foundational or groundbreaking at the time, even if its findings are no longer relevant to current conditions or reflect current thinking [one way to determine if a study is foundational or groundbreaking is to examine how often it has been cited in recent studies using the "Cited by" feature of Google Scholar ]. However, if an older study only relates to the research problem tangentially or it has not been cited in recent studies, then it may be more appropriate to list it under further readings .

7. Can I cite unusual and non-scholarly sources in my research paper? The majority of the citations in a research paper should be to scholarly [a.k.a., academic; peer-reviewed] studies that rely on an objective and logical analysis of the research problem based on empirical evidence that reliably supports your arguments. However, any type of source can be considered valid if it brings relevant understanding and clarity to the topic. This can include, for example, non-textual elements such as photographs, maps, or illustrations. A source can include materials from special or archival collections, such as, personal papers, manuscripts, business memorandums, the official records of an organization, or digitized collections. Citations can also be to unusual items, such as, an audio recording, a transcript from a television news program, a unique set of data, or a social media post. The challenge is knowing how to cite unusual and non-scholarly sources because they often do not fit within consistent citation rules of books or journal articles. Given this, consult with a librarian if you are unsure how to cite a source.

NOTE:   In any academic writing, you are required to identify which ideas, facts, thoughts, concepts, or declarative statements are yours and which are derived from the research of others. The only exception to this rule is information that is considered to be a commonly known fact [e.g., "George Washington was the first president of the United States"] or a statement that is self-evident [e.g., "Australia is a country in the Global South"]. Appreciate, however, that any "commonly known fact" or self-evidencing statement is culturally constructed and shaped by specific social and aesthetical biases . If you have any doubt about whether or not a fact is considered to be widely understood knowledge, provide a supporting citation, or, ask your professor for clarification about whether the statement should be cited.

Other Citation Research Guides

The following USC Libraries research guide can help you properly cite sources in your research paper:

• Citation Guide

The following USC Libraries research guide offers basic information on using images and media in research:

Listed below are particularly well-done and comprehensive websites that provide specific examples of how to cite sources under different style guidelines.

• Purdue University Online Writing Lab
• Southern Cross University Harvard Referencing Style
• University of Wisconsin Writing Center

This is a useful guide concerning how to properly cite images in your research paper.

• Colgate Visual Resources Library, Citing Images

This guide provides good information on the act of citation analysis, whereby you count the number of times a published work is cited by other works in order to measure the impact of a publication or author.

Measuring Your Impact: Impact Factor, Citation Analysis, and other Metrics: Citation Analysis [Sandy De Groote, University of Illinois, Chicago]

Automatic Citation Generators

The links below lead to systems where you can type in your information and have a citation compiled for you. Note that these systems are not foolproof so it is important that you verify that the citation is correct and check your spelling, capitalization, etc. However, they can be useful in creating basic types of citations, particularly for online sources.

• BibMe -- APA, MLA, Chicago, and Turabian styles
• DocsCite -- for citing government publications in APA or MLA formats
• EasyBib -- APA, MLA, and Chicago styles
• Son of Citation Machine -- APA, MLA, Chicago, and Turabian styles

NOTE:   Many companies that create the research databases the USC Libraries subscribe to, such as ProQuest , include built-in citation generators that help take the guesswork out of how to properly cite a work. When available, you should always utilize these features because they not only generate a citation to the source [e.g., a journal article], but include information about where you accessed the source [e.g., the database].

In any research paper, you draw on the work of other researchers and writers, and you must document their contributions by citing your sources, say Diana Hacker and Nancy Sommers in "A Pocket Style Manual, Eighth Edition." Citations, then, are the means by which you credit other researchers and writers when you use their work in your papers. Understanding how to cite sources can be tricky, particularly since there are different styles for writing papers , including the American Psychological Association, Modern Language Association, and Chicago (Turabian) styles. Electronic sources also come with their own specific citation rules in each of these styles. It's important to learn proper citation styles to avoid  plagiarism  in your research papers.

APA Citations

American Psychological Association (APA) style is often used in social sciences and other disciplines. With APA or any of the styles listed in this paper, you need to use a citation if you quote text from another source, paraphrase an author or authors' ideas, or refer to her work, such as a study, original thinking, or even an elegant turn of phrase. When you cite a source, you can't simply repeat most of the words from the work to which you are referring. You have to put the ideas into your own words, or you need to quote the text directly.

There are two parts to citations for APA and other styles: the short-form in line, which directs readers to a full entry at the end of a chapter or book. An in-line citation differs from a footnote, which is a note placed at the bottom of a page. An in-line citation—also called the  in-text citation —is placed within a line of text. To create an in-line citation, cite the name of the author and the date (in parentheses) of the article, report, book, or study, as this example from "A Pocket Style Manual" shows:

Cubuku (2012) argued that for a student-centered approach to work, students must maintain "ownership for thier goals and activities" (p. 64).

Note how you list the page number at the end of the in-text citation in parentheses followed by a period (if it is at the end of a sentence). If there are two authors, list the last name of each, as in:

"According to Donitsa-Schmidt and Zurzovsky (2014), ..."

If there are more than two authors, list the last name of the first author followed by the words "et al.," as in:

Herman et al. (2012) tracked 42 students over a three-year period (p. 49).

At the end of your paper, attach one or more pages titled "References." That section is essentially your biography. Readers of your paper can then turn to the references listing to read the full citations for each of the works you cited. There are actually many variations for references citations depending, for example, on whether you are citing a book, journal article, or newspaper story, or the many different kinds of media, including audio recordings and film.

the most common citation is to books. For such a citation, list the last name of the author, followed by a comma, followed by the first initial(s) of the author(s), followed by a period. You would put the year the book was published in parentheses followed by a period, then the title of the book in italics using sentence case , followed by a comma, the place of publication, followed by a colon, and then the publisher, followed by a period. "A Pocket Style Manual" gives this example:

Rosenberg, T. (2011). Join the club: How peer pressure can transform the world . New York, NY: Norton.​

Though the citations here won't print this way, use a hanging indent for the second and any subsequent lines in each citation. In a hanging indent in APA style, you indent every line after the first.

MLA Citations

MLA style is often used in English and other humanities papers. MLA follows the author-page style for in-text citations, notes Purdue OWL, an excellent citation, grammar, and writing website operated by Purdue University. Purdue gives this example of an in-text citation, which is also called parenthetical citation in MLA style. Note that in MLA style, page numbers don’t typically appear unless the sentence or passage is a direct quote from the original, as is the case here:

Romantic poetry is characterized by the "spontaneous overflow of powerful feelings" (Wordsworth 263).

At the end of the paper, attach a "Works Cited" page or pages, which is equivalent to the "References" section in APA style. "Works Cited" section citations are very similar in MLA and APA style, as in this example of a work with multiple authors from Purdue OWL:

Warner, Ralph, et al.  How to Buy a House in California . Edited by Alayna Schroeder, 12th ed., Nolo, 2009.

Note that you would also use a hanging indent in MLA, but it tends to be a bit shorter; move the second and subsequent lines in by three spaces. Spell out the first name of the author(s) in MLA style; add a comma before "et al."; use title case for the book, journal, or article title; omit the place of publication information; follow the name of the publisher with a comma; and list the date of publication at the end.

Chicago Style Citations

Chicago is the oldest of the three major writing and citation styles in the United States, having begun with the 1906 publication of the first Chicago style guide. For in-text citations, Chicago style, which comes from the "Chicago Manual of Style" from the University of Chicago Press, is pretty simple: the author's last name, date of publication, a comma, and page numbers, all in parentheses, as follows:

(Murav 2011, 219-220)

At the end of the paper, insert a list of references, which in Chicago style is called a bibliography. Books, journals, and other articles are cited in a manner similar to APA and MLA style. List the author's last name, a comma, and the full first name, followed by the title of the book in italics and title case, the place of publication, followed by a colon, followed by the publisher's name, a comma, and the date of publication, all in parentheses, followed by a comma and the page numbers.

Kate L. Turabian, in "A Manual for Writers" (a student-geared version of Chicago style), gives the following example:

Gladwell, Malcolm,  The Tipping Point: How Little Things Can Make a Big Difference  (Boston: Little Brown, 2000), 64-65.

You also use a hanging indent in the bibliography section of a Chicago style paper, with the indent moved in three spaces. For article or journal titles, list the title in regular (not italic) type encased in quotation marks.

Electronic Sources

Electronic source citations are similar to citations of published works except for two issues: You need to include the URL of the source, and a large percentage of online sources may not list an author. 

In APA style, for example, list an online source in the same way you would cite a book or article, except that you need to include the type of information you are accessing (in parentheses), as well as the URL. If the online source lacks a listed author, start with the name of the group or agency providing the information. "A Pocket Manual of Style" provides the following example of an APA electronic source citation:

U.S. Department of Agriculture, Economic Research Service. (2011). Daily intake of nutrients by food source: 2005-08 . ​[Data set]. Retrieved from http:www.ers.usda.gov/data-products/food-consumption-and-nutrient-intakes.aspx.

As with other citations, use a hanging indent for the second, third, and fourth lines of this source. For Chicago style, use the same method as described previously but add the URL, as in this example:

Brown, David. "New Burden of Disease Study Shows World's People Living Longer but with More Disability," Washington Post , December 12, 2012. http://www.washingtonpost.com/.

Note that Chicago style includes only the home-page URL and not the full URL; that can change, however, from one regime to the next.

MLA style used to require you to list the date you accessed the information, but that's no longer the case. To cite an electronic source, use the same style as discussed previously, but replace the period after the date with a comma and then list the URL.

An in-text citation is a short acknowledgement you include whenever you quote or take information from a source in academic writing. It points the reader to the source so they can see where you got your information.

In-text citations most commonly take the form of short parenthetical statements indicating the author and publication year of the source, as well as the page number if relevant.

We also offer a free citation generator and in-depth guides to the main citation styles.

What are in-text citations for, when do you need an in-text citation, types of in-text citation, frequently asked questions about in-text citations.

The point of an in-text citation is to show your reader where your information comes from. Including citations:

• Avoids plagiarism by acknowledging the original author’s contribution
• Allows readers to verify your claims and do follow-up research
• Shows you are engaging with the literature of your field

Academic writing is seen as an ongoing conversation among scholars, both within and between fields of study. Showing exactly how your own research draws on and interacts with existing sources is essential to keeping this conversation going.

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

An in-text citation should be included whenever you quote or paraphrase a source in your text.

Quoting means including the original author’s words directly in your text, usually introduced by a signal phrase . Quotes should always be cited (and indicated with quotation marks), and you should include a page number indicating where in the source the quote can be found.

Paraphrasing means putting information from a source into your own words. In-text citations are just as important here as with quotes, to avoid the impression you’re taking credit for someone else’s ideas. Include page numbers where possible, to show where the information can be found.

However, to avoid over-citation, bear in mind that some information is considered common knowledge and doesn’t need to be cited. For example, you don’t need a citation to prove that Paris is the capital city of France, and including one would be distracting.

Different types of in-text citation are used in different citation styles . They always direct the reader to a reference list giving more complete information on each source.

Author-date citations (used in APA , Harvard , and Chicago author-date ) include the author’s last name, the year of publication, and a page number when available. Author-page citations (used in MLA ) are the same except that the year is not included.

Both types are divided into parenthetical and narrative citations. In a parenthetical citation , the author’s name appears in parentheses along with the rest of the information. In a narrative citation , the author’s name appears as part of your sentence, not in parentheses.

Note: Footnote citations like those used in Chicago notes and bibliography are sometimes also referred to as in-text citations, but the citation itself appears in a note separate from the text.

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

At college level, you must properly cite your sources in all essays , research papers , and other academic texts (except exams and in-class exercises).

Add a citation whenever you quote , paraphrase , or summarize information or ideas from a source. You should also give full source details in a bibliography or reference list at the end of your text.

The exact format of your citations depends on which citation style you are instructed to use. The most common styles are APA , MLA , and Chicago .

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

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

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

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

A citation is the way you tell your readers that certain material in your work came from another source and gives your readers the information necessary to find that source again. Citations may include: Information about the Author(s) or Editor(s).

• The Title of the work
• The Publisher
• The Date published
• The Page Numbers of the material you are referencing
• Why should I cite sources?

Giving credit to the original author by citing sources is the only way to use other people's work without plagiarizing. But there are a number of other reasons to cite sources:

• Citations are extremely helpful to anyone who wants to find out more about your ideas and where they came from.
• Not all sources are good or right for your project -- your own ideas may often be more accurate or interesting than those of your sources. Proper citation will keep you from taking the rap for someone else's bad ideas.
• Citing sources shows the amount of research you've done.
• Citing sources strengthens your work by lending outside support to your ideas.

Doesn't citing sources make my work seem less original?

Not at all. Citing sources actually helps your reader distinguish your ideas from those of your sources. This will emphasize the originality of your own work. It also gives you greater credibility because you are demonstrating your knowledge on the subject and your understanding of the work that's already been done by others on the subject.

When do I need to cite?

Whenever you borrow words or ideas from another source, you need to acknowledge that source. The following situations almost always require a citation:

• Whenever you use quotes
• Whenever you paraphrase
• Whenever you use an idea that someone else has already expressed
• Whenever you make specific reference to the work of another
• Whenever someone else's work has been critical in developing your own ideas

• Within the text, references should be cited in numerical order according to their order of appearance. The numbered reference citation within text should be enclosed in brackets.
• In the case of two citations, the numbers should be separated by a comma [1,2]. In the case of more than two references, the numbers should be separated by a dash [5-7].
• References should be listed together at the end of the paper; footnotes should not be used for this purpose.
• References should be arranged in numerical order according to the sequence of citations within the text. Each reference should include the last name of each author followed by initials.

Research Paper: What is the state of the art on traditional medicine interventions for zoonotic diseases in the Indian subcontinent? A scoping review of the peer-reviewed evidence base

Traditional medicine (TM) interventions are plausible therapeutic alternatives to conventional medical interventions against emerging and endemic zoonotic diseases, particularly in low-and middle-income countries that may lack resources and infrastructure. Despite the growing popularity in the usage of TM interventions, their clinical safety and effectiveness are still contested within conventional healthcare in many countries.

We conducted a scoping review of the peer-reviewed literature that synthesises and maps the evidence on TM interventions for the treatment and prevention of zoonoses on the Indian subcontinent. The region, a global hotspot of biodiversity and emerging infections, is characterised by high prevalence of TM use. Based on the scientific literature, our review (1) maps the scope of the literature, (2) synthesises the evidence on the application of TM interventions for zoonoses, and (3) critically reflects on the state of TM and identifies areas for future research focus.

The evidence synthesis confirmed widespread usage of TM interventions for zoonoses on the subcontinent, with the majority of research reported from India, followed by Pakistan, Bangladesh, and Sri Lanka. Most of the reviewed studies reported on ethno-medicinal uses of plant species, primarily for treating dengue, tuberculosis, Escherichia coli infection, lymphatic filariasis and cholera. However, the evidence on the safety and effectiveness of these reported TM interventions is limited, indicating that these data are rarely collected and/or shared within the peer-reviewed literature.

This review thus highlights that, whilst TMs are already being used and could offer more widely accessible interventions against emerging and endemic zoonoses and ectoparasites, there is an urgent need for rigorous clinical testing and validation of the safety and effectiveness of these interventions.

Title: large investment model.

Abstract: Traditional quantitative investment research is encountering diminishing returns alongside rising labor and time costs. To overcome these challenges, we introduce the Large Investment Model (LIM), a novel research paradigm designed to enhance both performance and efficiency at scale. LIM employs end-to-end learning and universal modeling to create an upstream foundation model capable of autonomously learning comprehensive signal patterns from diverse financial data spanning multiple exchanges, instruments, and frequencies. These "global patterns" are subsequently transferred to downstream strategy modeling, optimizing performance for specific tasks. We detail the system architecture design of LIM, address the technical challenges inherent in this approach, and outline potential directions for future research. The advantages of LIM are demonstrated through a series of numerical experiments on cross-instrument prediction for commodity futures trading, leveraging insights from stock markets.
