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.

MLA Style specifies guidelines for formatting manuscripts and citing research in writing. MLA Style also provides writers with a system for referencing their sources through parenthetical citation in their essays and Works Cited pages. 

Writers who properly use MLA also build their credibility by demonstrating accountability to their source material. Most importantly, the use of MLA style can protect writers from accusations of plagiarism, which is the purposeful or accidental uncredited use of source material produced by other writers. 

If you are asked to use MLA format, be sure to consult the  MLA Handbook  (9th edition). Publishing scholars and graduate students should also consult the  MLA Style Manual and Guide to Scholarly Publishing  (3rd edition). The  MLA Handbook  is available in most writing centers and reference libraries. It is also widely available in bookstores, libraries, and at the MLA web site. See the Additional Resources section of this page for a list of helpful books and sites about using MLA Style.

Paper Format

The preparation of papers and manuscripts in MLA Style is covered in part four of the  MLA Style Manual . Below are some basic guidelines for formatting a paper in  MLA Style :

General Guidelines

• Type your paper on a computer and print it out on standard, white 8.5 x 11-inch paper.
• Double-space the text of your paper and use a legible font (e.g. Times New Roman). Whatever font you choose, MLA recommends that the regular and italics type styles contrast enough that they are each distinct from one another. The font size should be 12 pt.
• Leave only one space after periods or other punctuation marks (unless otherwise prompted by your instructor).
• Set the margins of your document to 1 inch on all sides.
• Indent the first line of each paragraph one half-inch from the left margin. MLA recommends that you use the “Tab” key as opposed to pushing the space bar five times.
• Create a header that numbers all pages consecutively in the upper right-hand corner, one-half inch from the top and flush with the right margin. (Note: Your instructor may ask that you omit the number on your first page. Always follow your instructor's guidelines.)
• Use italics throughout your essay to indicate the titles of longer works and, only when absolutely necessary, provide emphasis.
• If you have any endnotes, include them on a separate page before your Works Cited page. Entitle the section Notes (centered, unformatted).

Formatting the First Page of Your Paper

• Do not make a title page for your paper unless specifically requested or the paper is assigned as a group project. In the case of a group project, list all names of the contributors, giving each name its own line in the header, followed by the remaining MLA header requirements as described below. Format the remainder of the page as requested by the instructor.
• In the upper left-hand corner of the first page, list your name, your instructor's name, the course, and the date. Again, be sure to use double-spaced text.
• Double space again and center the title. Do not underline, italicize, or place your title in quotation marks. Write the title in Title Case (standard capitalization), not in all capital letters.
• Use quotation marks and/or italics when referring to other works in your title, just as you would in your text. For example:  Fear and Loathing in Las Vegas  as Morality Play; Human Weariness in "After Apple Picking"
• Double space between the title and the first line of the text.
• Create a header in the upper right-hand corner that includes your last name, followed by a space with a page number. Number all pages consecutively with Arabic numerals (1, 2, 3, 4, etc.), one-half inch from the top and flush with the right margin. (Note: Your instructor or other readers may ask that you omit the last name/page number header on your first page. Always follow instructor guidelines.)

Here is a sample of the first page of a paper in MLA style:

The First Page of an MLA Paper

Section Headings

Writers sometimes use section headings to improve a document’s readability. These sections may include individual chapters or other named parts of a book or essay.

MLA recommends that when dividing an essay into sections you number those sections with an Arabic number and a period followed by a space and the section name.

MLA does not have a prescribed system of headings for books (for more information on headings, please see page 146 in the MLA Style Manual and Guide to Scholarly Publishing , 3rd edition). If you are only using one level of headings, meaning that all of the sections are distinct and parallel and have no additional sections that fit within them, MLA recommends that these sections resemble one another grammatically. For instance, if your headings are typically short phrases, make all of the headings short phrases (and not, for example, full sentences). Otherwise, the formatting is up to you. It should, however, be consistent throughout the document.

If you employ multiple levels of headings (some of your sections have sections within sections), you may want to provide a key of your chosen level headings and their formatting to your instructor or editor.

Sample Section Headings

The following sample headings are meant to be used only as a reference. You may employ whatever system of formatting that works best for you so long as it remains consistent throughout the document.

Formatted, unnumbered:

Level 1 Heading: bold, flush left

Level 2 Heading: italics, flush left

Level 3 Heading: centered, bold

Level 4 Heading: centered, italics

Level 5 Heading: underlined, flush left

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)

Lipson, Charles. "Why Cite?"  Cite Right: A Quick Guide to Citation Styles--MLA, APA, Chicago, the Sciences, Professions, and More . Chicago: U of Chicago, 2006. Print.

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.

What is a Citation in Writing? Definition, Examples

• Posted on June 7, 2023

Writing is not only about expressing your own thoughts but also about using information from other sources to support them. But how do you show your readers where you got that information from? 

That’s where citations come in. Citations are a way of giving credit to the original authors and avoiding plagiarism. They also help your readers to find the original sources if they want to learn more. 

A proper citation includes:

• The author’s name.
• The title of the source.
• The publication date.
• The page number.
• The references page is where all the sources are listed.

You can use different citation styles depending on your writing purpose and audience.

You can also visit a writing lab to get help with citations and other aspects of writing. Citations can make your writing more credible and authoritative because they show that you have done the research and used reliable sources. They can also help search engines to rank your writing higher in the search results.

By the end of this article, you will have gained valuable insights into crafting accurate citations that adhere to formatting guidelines while effectively avoiding plagiarism throughout your writing process.

What is a Citation?

A citation is a way of giving credit to the source of information that you use in your writing. It shows your readers where you got the information from and how they can find it. It also helps you avoid plagiarism, which is copying someone else’s work without permission. A citation usually includes the following information:

• Original author information : This tells your readers who wrote the original source that you are using. For example, if you are citing a journal article, you would include the author’s name and affiliation.
• Date of publication of your copy : This tells your readers when you accessed the source that you are using. For example, if you are citing a web page, you would include the date that you visited the page.
• Year of publication of original copy : This tells your readers when the original source that you are using was published. For example, if you are citing a book, you would include the year that the book was printed.
• Page numbers you are using : This tells your readers which part of the source that you are using. For example, if you are citing a chapter in a book, you would include the page numbers that you are quoting or paraphrasing.
• The material you are using in the citation : This tells your readers what kind of information you are using from the source. For example, if you are citing a quote , a paraphrase, or a summary.

You should include citations in the text of your paper and on a separate references page at the end of your paper. 

Why is it Important to Cite Original Sources?

Citing original sources is important for several reasons. First, it shows respect and honesty to the original authors and sources you use, and it acknowledges their contribution and gives them credit for their work. 

Second, it helps you avoid plagiarism , which is using someone else’s work as your own without permission. Plagiarism is a serious academic offense that can negatively affect your reputation and career. 

Third, it shows the credibility and quality of your own work. It demonstrates that you have researched and used reliable and relevant sources to support your arguments. It also indicates that you have followed the writing style and format of your discipline and source type. 

Finally, it helps your readers to find and evaluate your sources. It provides them with a reference list where they can access the original sources if they want to learn more or check your information.

When Do You Need to Cite?

You must cite whenever you borrow ideas, words, or images from another source. Some examples of when you need to cite are:

• When you borrow an idea that someone else has already presented in their work
• When you use a direct quote from a source, using the same words as the author
• When you restate the author’s words in your own words
• When you mention a specific detail from the work of another, such as the title, date, or page number
• When you rely on the research and work of another to create your own ideas or arguments

You can cite your sources in different ways, such as using parentheses with the author’s last name and the year of publication or using footnotes or endnotes. You can also use Libguides to help you with citing your sources correctly for your research paper.

The Most Common Citation Style Guides

In today’s academic and professional world, various citation styles are used to appropriately credit the original authors of the sources referenced in a piece of writing. These citation style guides provide standardized formats for referencing sources, ensuring consistency and clarity across different disciplines.

MLA (Modern Language Association) Style

The MLA citations are popular among humanities scholars like literature and language researchers and use parenthetical citations within text along with an alphabetically arranged Works Cited page at the end.

APA (American Psychological Association) Style

APA citations are commonly used in social sciences such as psychology, education, and sociology. It emphasizes the author-date system for in-text citations and includes a detailed reference list at the end of the document.

In-Text Citation

In-text citations are references in your work that show the source of other authors’ ideas and words. They help readers find more information and avoid plagiarism. There are different in-text citation formats, such as parenthetical and narrative. They usually include the author’s name and publication year, and sometimes page numbers. They should match your reference list, which has all the sources you used.

Chicago Manual of Style

Chicago-style citations are a way of referencing sources in writing, especially in the humanities. They are based on the guidelines of The Chicago Manual of Style (CMOS), a style guide for American English. There are two types of Chicago-style citations: notes and bibliography and author-date. Notes and bibliography use footnotes or endnotes and a bibliography to cite sources, while author-date use parenthetical references and a reference list. Chicago-style citations help writers avoid plagiarism and show respect to the original authors and sources.

Turabian Style

Chicago/Turabian style, favored by historians and other fields that use extensive primary source material, offers two options: notes-bibliography system or author-date system, depending on discipline-specific preferences.

In conclusion, a citation is an essential aspect of writing that helps to acknowledge the original sources used in creating content. It ensures that credit is given where it’s due and prevents plagiarism. Knowing when to cite and which citation style guide to use can be crucial for businesses and marketing teams looking to create high-quality content.

APA In-Text Citations and Sample Essay 7th Edition

This handout focuses on how to format in-text citations in APA.

Proper citation of sources is a two-part process . You must first cite each source in the body of your essay; these citations within the essay are called in-text citations . You MUST cite all quoted, paraphrased, or summarized words, ideas, and facts from sources. Without in-text citations, you are technically in danger of plagiarism, even if you have listed your sources at the end of the essay.

In-text citations point the reader to the sources’ information on the references page. The in-text citation typically includes the author's last name and the year of publication. If you use a direct quote, the page number is also provided.

More information can be found on p. 253 of the 7th edition of the Publication Manual of the American Psychological Association.

Citation Rules

Direct quotation with the author named in the text.

Heinze and Lu (2017) stated, “The NFL shifted its responses to institutional change around concussions significantly as the field itself evolved” (p. 509).

Note: The year of publication is listed in parenthesis after the names of the authors, and the page number is listed in parenthesis at the end of the quote.

Direct Quotation without the Author Named in the Text

As the NFL developed as an organization, it “shifted its responses to institutional change around concussions significantly” (Heinze & Lu, 2017, p. 509).

Note: At the end of the quote, the names of the authors, year of publication, and page number are listed in parenthesis.

Paraphrase with 1-2 Authors

As the NFL developed as an organization, its reactions toward concussions also transformed (Heinze & Lu, 2017).

Note: For paraphrases, page numbers are encouraged but not required.

Paraphrase with 3 or More Authors

To work toward solving the issue of violence in prisons begins with determining aspects that might connect with prisoners' violent conduct (Thomson et al., 2019).

Direct Quotation without an Author

The findings were astonishing "in a recent study of parent and adult child relationships" ("Parents and Their Children," 2007, p. 2).

Note: Since the author of the text is not stated, a shortened version of the title is used instead.

Secondary Sources

When using secondary sources, use the phrase "as cited in" and cite the secondary source on the References page.

In 1936, Keynes said, “governments should run deficits when the economy is slow to avoid unemployment” (as cited in Richardson, 2008, p. 257).

Long (Block) Quotations

When using direct quotations of 40 or more words, indent five spaces from the left margin without using quotation marks. The final period should come before the parenthetical citation.

At Meramec, an English department policy states:

To honor and protect their own work and that of others, all students must give credit to proprietary sources that are used for course work. It is assumed that any information that is not documented is either common knowledge in that field or the original work of that student. (St. Louis Community College, 2001, p. 1)

Website Citations

If citing a specific web document without a page number, include the name of the author, date, title of the section, and paragraph number in parentheses:

In America, “Two out of five deaths among U.S. teens are the result of a motor vehicle crash” (National Center for Injury Prevention and Control, 2004, Overview section, para. 1).
