How to Cite a Case Study in APA, MLA & Harvard

Case Study Citation Builder

Type the details once and the builder assembles a reference-list entry, an in-text citation and a note explaining which field landed where — for APA 7, MLA 9 and Harvard at the same time. Switch the source type and the pattern changes with it, because a journal case and a website case do not cite alike. Your fields save to this browser only.

Why case studies are tricky to cite

A case study breaks the habit every other source builds. A book is a book; a journal article lives inside a journal. But a case study is a work inside a work more often than not — Rosa Alvarez wrote the case, and you read it inside Professor Nair's course pack, inside the Journal of Family Business Practice, or as a PDF on the publisher's site. The citation has to report both layers: who wrote it, and where you opened it.

Most lost marks come from picking one layer and ignoring the other. Cite only the case and your reader cannot find your copy; cite only the course pack and you have credited the wrapper, not the writer. The marker wants both, in the order your style guide demands — and the case's home decides the formatting:

• Course pack or textbook — someone edited the collection, so an editor joins the entry and the case behaves like a book chapter.
• Journal — the case behaves like an article: volume, issue and pages matter, and the journal name takes the italics.
• Business school teaching case — often has no container at all. The school stands in as publisher, the way a report would.
• Website — the site name is the container, a URL closes the entry, and Harvard wants the date you read it.

Because a case is usually one of many sources in a paper, sort the full set before you format anything. When the reading list feeds a review chapter, the literature review matrix keeps each case's author, year and finding on one row, so the citations stop shuffling while you write.

APA 7: the pattern and the four source types

APA builds every case-study entry from the same skeleton: Author, A. A. (Year). Title of case. Where it lives. The year sits in parentheses right after the author because APA's in-text citation leans on it. What changes by source type is which element takes the italics and which extras — editor, pages, bracketed label — appear.

Three details decide most of the marks. First, capitalization: APA writes case titles in sentence case — capitalize the first word, the word after a colon and any proper nouns. Second, the italics flip: a case inside a course pack is a chapter, so the pack takes the italics and the case title stays roman; a teaching case or a web case stands alone, so the case title takes the italics with a [Case study] label. Third, the pages: pp. marks course-pack ranges (pp. 40–55); journal pages list bare after the issue number.

Two authors join with an ampersand in the entry and the citation — Alvarez, R., & Okafor, D. — and three or more start with the first surname plus et al. If the journal case came from a database, cite it exactly like the print version; APA does not want the database name. When an entry still fights back, the APA citation generator assembles it field by field, and the annotated APA reference page shows where it sits in the finished list.

MLA 9: the pattern and the italics decision

MLA stacks its core elements in a fixed order: Author. "Title of Case." Container, other contributors, publisher, year, pages. No year after the author's name — the date waits until late in the entry — and the case title always wears quotation marks, because MLA treats it as a short work inside something bigger.

Italics or quotation marks?

The decision rule is simpler than it looks. Short work → quotation marks; container → italics. The case title is the short work, so it sits in quotes; the course pack, the journal and the website take the italics. The one exception: the teaching case with no container gets no italics at all, and the business school stands alone as the publisher, roman like any other press.

Notice what MLA does with names: the first author inverts (Alvarez, Rosa), a second author stays in normal order after "and," and three or more collapse to the first author plus et al. Titles keep their title case here — MLA never converts to sentence case. The URL drops the https:// but keeps the rest. The in-text half of these rules — surname plus page, no year, no comma — is drilled across twenty scenarios in the MLA in-text citation examples guide.

Harvard: the pattern and the accessed-date rules

Harvard leads with the author and year — Author (Year) 'Title', container details — and keeps the case title in single quotation marks for cases that live inside a container. One warning first: "Harvard" is a family of local variants, not one enforced standard, so your department's guide outranks this page. The version below follows the widely used Cite Them Right shape.

The accessed-date rules

Harvard asks for (Accessed: day month year) after the URL of any online source, because web pages move — the date pins the version you actually read. Write it out in full: 6 January 2026, never 06/01/26, which reads as a different day on the other side of the Atlantic. Print journals and books never take an access date, and some departments skip the date when the source has a publication date — the local guide outranks this page. Initials, not full first names, follow the surname in most Harvard variants: Alvarez, R. The Harvard citation generator applies one variant mechanically, which is worth more than memory when the list runs long.

In-text citations: parenthetical vs narrative

Every in-text citation comes in two costumes. The parenthetical form tucks the credit at the end of the sentence; the narrative form names the author inside your sentence and lets the parenthesis carry only what is left. Good writing mixes them — a paper where every sentence ends in a full parenthesis reads like a list.

All examples below reuse the invented Greenfield Roasters case and quote page 47:

The tells that separate the styles at a glance: a year inside the parenthesis means APA or Harvard; a bare surname and page means MLA; an ampersand between two surnames means APA, because MLA and Harvard spell out and. Two authors change every row — APA writes (Alvarez & Okafor, 2023), MLA and Harvard write (Alvarez and Okafor, 2023), with MLA's page riding along for quotes: (Alvarez and Okafor 47). Three or more shorten to the first surname plus et al. in all three styles. Wherever it sits, the citation lands before the sentence-ending period — and if you are deciding what the surrounding paragraph owes as evidence, the split between a discussion section and a conclusion settles that.

Special cases: no author, no date, secondhand cases, direct quotes

Real reading lists rarely cooperate. Four situations cover almost every awkward case study you will meet.

No named author

When no person or organization takes the byline, the title moves into the author slot and alphabetization follows the title. The APA reference starts with the title, and the in-text citation shortens it inside quotation marks — ("Greenfield Roasters," 2023) — so a six-word title does not crowd the sentence. MLA shortens the same way without the year: ("Greenfield Roasters" 47). Never write Anonymous unless the source itself prints that word on the byline.

No date

Teaching cases get reissued without dates more often than any other source type. If the year is genuinely missing, APA and Harvard write n.d. where the year would sit — Alvarez, R. (n.d.) — and the in-text pair reads (Alvarez, n.d.). MLA leaves the year out of the entry rather than printing a placeholder. Check the copyright page or the site footer before you surrender: reissue years hide there.

A case study quoted inside another source

Sometimes you only meet a case secondhand — Okafor's survey, quoted inside the Alvarez case you actually read. All three styles handle it with a two-part citation and only one reference entry. APA: (Okafor, as cited in Alvarez, 2023). MLA: (Okafor qtd. in Alvarez 47). Harvard: (Okafor, cited in Alvarez, 2023). Only Alvarez's case — the source you opened — enters the reference list. Treat this as a last resort: if the library can fetch Okafor's original, cite it directly, because markers read heavy "as cited in" traffic as a thin reference list.

Quoting the case directly

Paraphrases can lean on the author-year pair alone, but a direct quotation owes the reader a pinpoint. APA and Harvard add p. for a single page and pp. for a spread: (Alvarez, 2023, p. 47). MLA needs no p. — the bare number follows the surname: (Alvarez 47). If your course-pack copy has no page numbers, do not borrow the ones from the original print edition; cite what the copy actually shows and tell your marker which version you used.

Reference-list placement and formatting

One correct entry still loses marks in the wrong neighborhood. The list — APA calls it References, MLA calls it Works Cited, Harvard answers to Reference list or Bibliography depending on the department — sorts entries alphabetically by their first element: the surname, or the title when no author exists. Alvarez's case lands before Okafor's survey; a no-author case alphabetizes under G for Greenfield, ignoring A, An and The. One author, two cases? APA orders them by year, earliest first, and labels the second (2023b) if both share a year.

Formatting is uniform across the styles: the first line of each entry sits at the left margin and every later line indents — the hanging indent. Word hides the setting under Paragraph → Special → Hanging; Google Docs uses Format → Line & paragraph spacing → Indentation options. The page layouts around the list differ by style, so set them from the source: the APA paper format and MLA paper format guides each walk the setup, and the APA reference page example shows a finished list with the indents visible. If you would rather not hand-build the list, the bibliography generator assembles entries in your chosen style while you read.
