Navigating the complexities of academic writing can be challenging, and one of the most frequent hurdles students face is proper citation. Understanding how to correctly attribute sources is not just about following rules; it's fundamental to academic integrity, credibility, and scholarly conversation. Different academic disciplines often prefer different citation styles, with APA, MLA, and Chicago being the most common. Feeling confused? You're not alone.
This comprehensive proper citation guide is designed to demystify the core principles and specific formats of APA, MLA, and Chicago styles. Whether you're writing a psychology paper, a literary analysis, or a historical research project, mastering the appropriate citation method is crucial for success. It helps you avoid plagiarism, strengthens your arguments by showing the foundation of your research, and allows your readers to locate the original sources themselves.
Let's break down these essential citation styles to help you reference your sources accurately and confidently.
Before diving into the specifics of each style, it's vital to understand why citation matters so much in academic work. It's more than just a formatting requirement; it's the bedrock of ethical scholarship.
This is often the most emphasized reason. Plagiarism, the act of presenting someone else's work or ideas as your own, is a serious academic offense. Proper citation clearly distinguishes your original thoughts and analysis from the information and ideas you've gathered from other sources. Failing to cite correctly, even unintentionally, can lead to accusations of plagiarism. For a deeper understanding of this critical topic, explore our resource on Understanding and Avoiding Plagiarism.
When you cite reputable sources to support your claims, you demonstrate that your arguments are well-researched and grounded in existing knowledge. This significantly enhances the credibility and authority of your work. Readers are more likely to trust your conclusions if they see they are built upon a solid foundation of evidence acknowledged through citations.
Academic work is a conversation. Researchers build upon the discoveries and insights of those who came before them. Citing sources is a way of acknowledging the intellectual contributions of other authors and researchers. It's an ethical obligation to give credit for the original ideas and hard work that informed your own project.
Citations act as a roadmap for your readers. A complete and accurate citation provides all the necessary information for an interested reader (like your professor, a peer, or another researcher) to locate the original source material. This allows them to verify your interpretation, explore the topic further, or use the source in their own research.
Universities, departments, specific courses, and academic journals almost always have strict requirements regarding citation style and formatting. Adhering to the specified style (APA, MLA, Chicago, etc.) is essential for meeting these requirements and ensuring your work is accepted and graded appropriately.
Mastering citation is, therefore, a fundamental skill for any student or researcher. This proper citation guide aims to equip you with the knowledge to do so effectively.
Regardless of the specific style (APA, MLA, or Chicago), most citation systems consist of two main interconnected parts:
To create these components, you generally need key pieces of information about each source:
Gathering this information as you research will save you significant time and effort later.
The American Psychological Association (APA) style is widely used in the social sciences (like psychology, sociology, education, communication) and increasingly in other fields like business and nursing. The 7th edition is the latest version, emphasizing clarity, conciseness, and digital source citation.
APA uses the author-date system for in-text citations.
The reference list appears at the end of the paper, titled "References" (centered, bold). Entries are alphabetized by the first author's last name. Use a hanging indent (the first line is flush left, subsequent lines are indented).
General Formatting: Double-spaced. Italicize titles of longer works (books, journals) and their volume numbers. Use sentence case for article and book chapter titles (capitalize only the first word, proper nouns, and the first word after a colon).
Common Source Examples (APA 7th):
Journal Article (with DOI): Author, A. A., Author, B. B., & Author, C. C. (Year). Title of the article in sentence case. Title of Journal in Title Case and Italics, Volume(Issue), page range. https://doi.org/xxxx
Example: Schmidt, F. L., & Hunter, J. E. (2004). General mental ability in the world of work: Occupational attainment and job performance. Journal of Personality and Social Psychology, 86(1), 162–173. https://doi.org/10.1037/0022-3514.86.1.162
Book: Author, A. A. (Year). Title of book in sentence case and italics. Publisher.
Example: Brown, B. (2018). Dare to lead: Brave work. Tough conversations. Whole hearts. Random House.
Chapter in an Edited Book: Author, A. A., & Author, B. B. (Year). Title of chapter in sentence case. In C. C. Editor & D. D. Editor (Eds.), Title of book in sentence case and italics (pp. page range). Publisher.
Example: O'Neil, J. M., & Egan, J. (1992). Men's and women's gender role journeys: A metaphor for healing, transition, and transformation. In B. R. Wainrib (Ed.), Gender issues across the life cycle (pp. 107–123). Springer Publishing Company.
Webpage on a Website (Individual Author): Author, A. A. or Group Name. (Year, Month Day). Title of specific page in sentence case and italics. Website Name. Retrieved Month Day, Year, from URL (Only include retrieval date if content is designed to change over time and the page is not archived).
Example: Streefkerk, R. (2023, June 12). APA Citation Generator. Scribbr. Retrieved October 26, 2023, from https://www.scribbr.com/apa-citation-generator/
Webpage on a Website (Group Author): Group Name. (Year, Month Day). Title of specific page in sentence case and italics. Website Name. URL
Example: Centers for Disease Control and Prevention. (2022, August 11). How COVID-19 spreads. U.S. Department of Health & Human Services. https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/how-covid-spreads.html
Key APA 7th Changes: Publisher location is no longer required. DOIs are formatted as URLs. Include up to 20 authors in the reference list. Use "et al." for 3+ authors in-text from the start.
The Modern Language Association (MLA) style is the standard for the humanities, including fields like literature, arts, philosophy, religion, and languages. The 9th edition emphasizes a template of core elements applicable to nearly any source type.
MLA uses the author-page number system for in-text citations.
The Works Cited list appears at the end of the paper, titled "Works Cited" (centered, not bold or italicized). Entries are alphabetized by the first element (usually author's last name or title). Use a hanging indent. Double-space the entire list.
MLA Core Elements Template: MLA 9th edition uses a container system based on nine core elements. You include the elements relevant to your source, in order, followed by the specified punctuation.
Common Source Examples (MLA 9th):
Book: Author's Last Name, First Name. Title of Book in Title Case and Italics. Publisher, Publication Year.
Example: Atwood, Margaret. The Handmaid's Tale. McClelland & Stewart, 1985.
Journal Article (from Database): Author's Last Name, First Name. "Title of Article in Title Case and Quotation Marks." Title of Journal in Title Case and Italics, vol. Volume Number, no. Issue Number, Publication Date, pp. Page Range. Name of Database in Italics, DOI or URL (omit http:// or https:// for URLs unless needed for clarity or if using a permalink).
Example: Piper, Andrew. "Rethinking the Print Object: Goethe and the Book of Everything." PMLA, vol. 121, no. 1, Jan. 2006, pp. 124-38. JSTOR, www.jstor.org/stable/25486292.
Webpage: Author's Last Name, First Name (if known). "Title of Page or Article in Quotation Marks." Title of Website in Italics, Publication Date (Day Month Year), URL (omit http:// or https://).
Example: Hollmichel, Stefanie. "The Reading Brain: Differences between Digital and Print." So Many Books, 25 Apr. 2013, somanybooksblog.com/2013/04/25/the-reading-brain-differences-between-digital-and-print/.
Work in an Anthology: Author's Last Name, First Name. "Title of Work (e.g., Story, Poem) in Quotation Marks." Title of Anthology in Italics, edited by Editor's First Name Last Name, Publisher, Publication Year, pp. Page Range.
Example: Poe, Edgar Allan. "The Tell-Tale Heart." Literature: Reading Fiction, Poetry, and Drama, edited by Robert DiYanni, 6th ed., McGraw Hill, 2007, pp. 75-79.
Key MLA 9th Points: Emphasis on containers (a source might be within a larger container, like a journal article within a database). URLs are generally recommended but DOIs are preferred if available. Flexibility is key; include elements needed for identification and location.
The Chicago Manual of Style (CMOS) is widely used in history, and also frequently in the arts, humanities, and some social sciences. It's known for its flexibility, offering two distinct citation systems:
Always check which system your instructor or publisher requires. This guide will cover both.
The bibliography appears at the end, titled "Bibliography" (centered). Entries are alphabetized by author's last name. Use a hanging indent. Formatting differs slightly from notes (e.g., author Last Name, First Name; periods separate main elements).
Common Source Examples (Chicago 17th NB - Bibliography Entries):
Book: Author's Last Name, First Name. Title of Book in Title Case and Italics. Place of Publication: Publisher, Year.
Example: Dudziak, Mary L. Cold War Civil Rights: Race and the Image of American Democracy. Princeton: Princeton University Press, 2000.
Journal Article: Author's Last Name, First Name. "Title of Article in Title Case and Quotation Marks." Title of Journal in Title Case and Italics Volume Number, no. Issue Number (Month or Season Year): Page Range. DOI or URL.
Example: Weinstein, Joshua I. "The Market in Plato's Republic." Classical Philology 104, no. 4 (October 2009): 439–58. https://doi.org/10.1086/650979.
Chapter in an Edited Book: Author's Last Name, First Name. "Title of Chapter in Title Case and Quotation Marks." In Title of Book in Title Case and Italics, edited by Editor's First Name Last Name, Page Range. Place of Publication: Publisher, Year.

Webpage: Author's Last Name, First Name or Owning Organization. "Title of Page in Title Case and Quotation Marks." Title of Website. Publication Date or Last Modified Date (if available; otherwise, access date). URL.
Example: Google. "Privacy Policy." Google Policies & Terms. Last modified April 17, 2023. https://policies.google.com/privacy.
This system looks very similar to APA's in-text citations.
The reference list appears at the end, titled "Reference List" or "References" (centered). Entries are alphabetized by author's last name. Use a hanging indent. Formatting is similar to the NB bibliography but with the year moved up after the author's name.
Common Source Examples (Chicago 17th Author-Date - Reference List Entries):
Book: Author's Last Name, First Name. Year. Title of Book in Title Case and Italics. Place of Publication: Publisher.
Example: Dudziak, Mary L. 2000. Cold War Civil Rights: Race and the Image of American Democracy. Princeton: Princeton University Press.
Journal Article: Author's Last Name, First Name. Year. "Title of Article in Title Case and Quotation Marks." Title of Journal in Title Case and Italics Volume Number (Issue Number): Page Range. DOI or URL.
