Learning how to cite a case study is a core academic skill. A proper citation gives credit where it’s due and allows your reader to find the source themselves. It’s your map back to the original information, so getting it right is essential for a credible paper.
TLDR: To cite a case study, you almost always need four key pieces of information: the writer’s name, the publication year, the title of the case study, and details about the publication or publisher. The specific format you use will depend on the citation style your instructor requires, such as the common APA, MLA, or Chicago style.
The Anatomy of a Case Study Citation
Think of a citation’s skeletal structure. It has essential bones that hold it together. Getting these right is the first step toward mastering citations. Whether it’s a famous Harvard Business School case or a chapter in a textbook, the general format always relies on these four core elements:
- Creator — the person or organization responsible for the work
- Date — the publication year (or “n.d.” if no date is available)
- Document name — the full title of the case study
- Source details — the publisher, institution, URL, or DOI
I remember staring at my first business school case study, the crisp feel of the printed report in my hands, wondering how to translate its title page into a formal reference.
A complete reference list citation appears at the end of your paper, while a short in-text citation appears directly in your writing. Both pieces work together to give your reader a clear path back to the original case study.
Where to Find Citation Information on a Case Study
Before building a citation, you need to locate the required details. Most institutional case studies, such as those from Harvard Business School, Ivey Publishing, or the Darden School, include a cover page or title page. That page usually carries the creator’s full name, the case number, the institution or publisher, and the publication date.
If the case study is available through a journal or academic database, check the article metadata. The database record lists the DOI (Digital Object Identifier), the journal name, the volume and issue, and the page range. For a case study published as a standalone book or report, look at the title page and the verso page (the back of the title page) for the publisher’s location and date.
When you find a case study on a website or through an institutional repository, copy the full URL and the date you accessed it. Some style guides require the access date when citing web sources. If you need to cite different types of online content, our guide on how to cite a website in an essay covers the access-date and URL rules across all major formats.
How to Cite a Case Study in APA 7th Edition
APA format is the most common set of rules used in social sciences, business, and education. The APA Publication Manual (7th edition) specifies a clear reference structure. You list the creator’s last name and initials first, followed by the publication date in parentheses, the italicized document name, a case number if available, and the publisher or institution. If you found the case study through an online source, add the URL or DOI at the end with no period.
APA Reference List Format
Creator, A. A., & Creator, B. B. (Year). Name of case study (Case No. XXX). Publisher Name. URL or DOI
If the case study has no named individual creator, use the organization’s name in place of a personal name. If there is no date, write “n.d.” in the parentheses. If you found the source through a database, add the DOI when one exists. A DOI is preferred over a plain URL because it never changes, even when a journal moves its content to a new website.
APA In-Text Citation Format
For a paraphrase, use (Creator, Year). For a direct quote, add a page number: (Creator, Year, p. X). If the case study has three or more contributors, use “et al.” from the first citation onward: (Hill et al., 2008).
If you are working quickly, an APA citation generator can produce a draft reference, but always verify the output against the style manual before submitting your paper.
How to Cite a Case Study in MLA 9th Edition
MLA format is used primarily in the humanities. The 9th edition introduced the “container” model, where each piece of bibliographic information fits into a specific slot. For a standalone case study, the contributor’s full last name comes first, followed by the italicized document name, the publisher, the year, and the URL without the “https://” prefix.
MLA Works Cited Format
Contributor, First Name. Name of Case Study. Publisher, Year, URL.
If the case study appears as a chapter inside a textbook or collected volume, treat it as a chapter in a book. Put the chapter name in quotation marks, then add the book name in italics, the editor, the publisher, the year, and the page range. The MLA 9th edition guide from the University of North Carolina has a reliable breakdown of container rules for academic works.
MLA In-Text Citation Format
MLA uses a parenthetical format with the contributor’s last name and a page number, if available: (Hill et al. 8). If there is no page number, use the contributor’s name alone: (Hill et al.). For a work with no named contributor, use a shortened version of the case study’s name in the parenthetical.
Use an MLA citation generator as a starting point, then cross-check the works cited entry against the manual’s container rules.
How to Cite a Case Study in Chicago 17th Edition
Chicago format has two systems: Notes-Bibliography (NB) and Author-Date. Humanities papers use Notes-Bibliography, while social sciences papers use Author-Date. Knowing which system your instructor requires before you start is important.
Notes-Bibliography uses footnotes or endnotes for in-text references and a bibliography at the end. Author-Date uses a parenthetical reference like (Hill 2008) in the text and a reference list at the end.
Chicago Notes-Bibliography Format
Contributor, First Name. Name of the Case Study. Publishing City: Publisher, Year. URL.
For a shortened footnote (used after the first full citation), give only the last name, a short form of the document name, and the page: Hill, “HCL Technologies,” 4.
Chicago Author-Date Format
Contributor, First Name. Year. Name of the Case Study. Publishing City: Publisher. URL.
You can also use a Chicago citation generator to draft your reference and then check it against the correct system for your paper.
Citation Style Comparison at a Glance
While different citation formats like APA, MLA, and Chicago share core components, their presentation varies significantly. The format for a publication from Harvard Business School Publishing will look different in each. Below is a table that breaks down the structure and examples for each, helping you see the precise differences for your report or essay.
| Style | Reference / Bibliography Structure | Full Citation Example | In-Text Example |
|---|---|---|---|
| APA 7 | Creator, A. A. (Publication Year). Document name (Case #). Publisher. URL | Hill, L., Khanna, T., & Stecker, E. (2008). HCL Technologies (A) (Case 408-004). Harvard Business School. https://www.hbs.edu/faculty/Pages/item.aspx?num=34784 | (Hill et al., 2008) |
| MLA 9 | Contributor, A. A. Document Name. Publisher, Publication Year, URL (without https://). | Hill, Linda A., et al. HCL Technologies (A). Rev. edition, Harvard Business School, 2008, www.hbs.edu/faculty/Pages/item.aspx?num=34784. | (Hill et al. 8) |
| Chicago 17 (Notes-Bib) | Contributor, A. A. Name of the Case Study. Publishing City: Publisher, Publication Year. URL. | Hill, Linda A., Tarun Khanna, and Emily Stecker. HCL Technologies (A). Boston: Harvard Business School, 2008. https://www.hbs.edu/faculty/Pages/item.aspx?num=34784. | (Footnote format) |
For a complex reference, a citation generator can be a helpful starting point, but always double-check its output against your style guide’s rules.
Common Mistakes When Citing a Case Study
One of the most common errors is treating a case study like a journal article. A case study usually has a publisher (such as Harvard Business School or Ivey Publishing) rather than a journal name and volume number. Always check what information is available on the cover page of the case study itself before choosing a citation template.
Another frequent issue is missing the case number. Many institutional case studies have a specific case number on the cover page. In APA format, this goes in parentheses after the italicized document name. In MLA and Chicago, the case number is omitted unless it is the only identifying detail available.
A third common error is citing a case study found through a university’s online library the same way you would cite one purchased directly from a business school. When you access the case through a library database or a website, add the database name or the URL. The retrieval details help your reader find the same version of the document. If you regularly cite academic sources, check out our guide on how to cite an article in an essay for a useful comparison of source types, and our overview of how to introduce quotations when you quote directly from a case study in your paper.
What’s the difference between an in-text citation and a reference list entry?
An in-text citation is a brief note inside your paragraph (e.g., Smith, 2023) that points the reader to the full citation. The reference list entry is the complete publication detail at the end of your document, providing all the information needed to find the case study.
Do I need a page number in my in-text citation for a case study?
In APA format, you must include a page number for direct quotes. For paraphrased ideas from the report, a page number is recommended but not strictly required. Always check your instructor’s preference for citing a specific case study.
Can I cite a case study from a textbook the same way?
If the case study is a chapter or section inside a textbook, treat it as a book chapter in APA and MLA. Include the textbook editor(s), the chapter name, and the book name. The format differs from a standalone case study published by a business school or research firm, so check the specific section on book chapters in your style manual.
How do I cite a case study with no named author?
When there is no named individual contributor, use the organization that published the case study in place of a personal name. For example, a report published by a consulting firm with no listed contributor would start with the firm’s name in both APA and MLA. In Chicago Notes-Bibliography format, the organization’s name goes at the start of the bibliography entry as well.
