How to Cite an ISBN in APA
Updated August 2026
Citing an isbn in APA comes down to one template and a handful of rules. Below: the exact 7th 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 APA format
Author, A. A. (Year). Title of book in sentence case (Edition ed.). Publisher.
APA (7th edition) formats a book (by ISBN) reference as shown above. A real example, generated by our citation engine:
Martin, R. C. (2008). Clean Code: A Handbook of Agile Software Craftsmanship. Prentice Hall.
In-text(Martin, 2008)
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 APA 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
APA's formatting rules at work
- Authors are inverted with initials: Alvarez, M.
- Titles use sentence case — only the first word, proper nouns, and the word after a colon are capitalized
- The date comes right after the author, in parentheses
- DOIs are formatted as full links: https://doi.org/10.xxxx
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 APA
APA cites in the text with author and date: (Alvarez, 2024) for a paraphrase, with a page or paragraph locator for quotes — (Alvarez, 2024, p. 12) or (Alvarez, 2024, para. 3). Three or more authors shorten to et al. from the first citation: (Harris et al., 2020).
No author? A short version of the title stands in, in quotes: ("First Words of Title," 2024). No date? Use (Author, n.d.).
Building the References
Every in-text citation pairs with a full entry on the References 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 APA requires.
