Doi Vs Isbn: Key Differences & Comparison | CASRAI
A DOI and an ISBN are both identifiers for published works, but they serve different purposes. A DOI is a resolvable persistent identifier for digital research outputs such as articles and datasets; an ISBN is a product identifier for a specific edition of a book.

| Resolvable? | Yes — resolves via https://doi.org/ to current metadata | No — a catalogue/product code, not a web resolver |
| Standard | ISO 26324:2022 | ISO 2108 |
| Issued by | Registration agencies (Crossref, DataCite, etc.) | National ISBN agencies, coordinated by the International ISBN Agency |
| Carries metadata | Yes — structured, machine-readable, updatable | Minimal — points to bibliographic records held elsewhere |

Common questions
FAQ
Can a book have both a DOI and an ISBN?+
Yes — and scholarly books often do. The ISBN identifies the specific print or e-book edition for the book trade and libraries, while DOIs are assigned to the book as a whole and frequently to each chapter, so individual chapters can be cited and linked.
Which should I use to cite a book chapter?+
Use the DOI if the chapter has one — it resolves to the chapter and supports citation linking. Cite the ISBN to identify the specific book edition. Many references include both: the DOI for resolution and the ISBN for the physical edition.
Why is a DOI resolvable but an ISBN is not?+
A DOI is built on a resolver (doi.org) that redirects to the current landing page, so it is actionable as a link. An ISBN is a product code designed for cataloguing and commerce; you look it up in a catalogue or bookseller database rather than resolving it directly.
Do datasets get an ISBN?+
No. ISBNs are for books. Datasets, software, and articles are identified with DOIs (typically via DataCite or Crossref), not ISBNs.
