How to Cite an ISBN in MLA
Updated August 2026
Citing an isbn in MLA comes down to one template and a handful of rules. Below: the exact 9th edition format, a real example produced by our citation engine, and the in-text form — or paste your source into the generator and copy the finished citation.
The MLA format
Author Last, First. Title of Book. Edition ed., Publisher, Year.
MLA (9th edition) formats a book (by ISBN) reference as shown above. A real example, generated by our citation engine:
Martin, Robert C. Clean Code: A Handbook of Agile Software Craftsmanship. Prentice Hall, 2008.
In-text(Martin)
Finding the pieces
Or skip the hunt: Paste the 10- or 13-digit ISBN into the generator's ISBN tab — hyphens optional, and every field is filled from the source's own record — then select MLA on the result.
- Copyright page — the back of the title page lists the ISBN
- Back cover — above or below the barcode
- Retailer/library listings — product details on Amazon, Google Books, or WorldCat
- eBook store pages — eBooks carry their own ISBNs, sometimes different from print
MLA's formatting rules at work
- Only the first author's name is inverted; co-authors appear in natural order with full first names
- Titles use Title Case — capitalize all principal words
- Source titles take quotation marks inside a container; standalone works are italicized
- The date sits near the end of the entry, in day-month-year form with abbreviated months
ISBN-specific pitfalls
- An ISBN identifies a book edition — citing by ISBN guarantees you cite the edition you actually used
- The ISBN itself never appears in the finished citation in any style
- Print and eBook editions may have different ISBNs and different years — cite yours
In-text citations in MLA
MLA cites in the text with author and page: (Alvarez 12) — no comma, no year. Sources without page numbers (most web sources) cite the author alone: (Alvarez). Three or more authors use et al.: (Harris et al. 360).
No author? A shortened title stands in — quoted for articles and pages, italicized for whole works: ("First Words of Title").
Building the Works Cited
Every in-text citation pairs with a full entry on the Works Cited page, alphabetized by author. Add each citation to your bibliography as you generate it, and the Bibliography Builder assembles and exports the finished page to Word with the title, ordering, and indentation MLA requires.
