Wiktionary:Book sources
This page links to catalogs of libraries, booksellers, and other book sources where you will be able to search for the book with ISBN MAGICNUMBER.
Notes
[edit]
- Use Special:Booksources to manually search on an ISBN.
- Learn how to bypass this page and go to the same book source every time.
- An ISBN identifies a specific edition of a book, and any given title may therefore have a number of different ISBNs. See xISBN below for finding other editions.
- An ISBN registration, even one corresponding to a book page on a major book distributor database is not definite proof that such a book actually exists. A title may have been cancelled or postponed after the ISBN was assigned. Both ISBN and other registration have been abused in attempted hoaxes on Wikipedia in the past.
- The master copy of this page is located at Wiktionary:Book sources.

Find other editions
[edit]- Related ISBNs from xISBN. This service will look up ISBNs for different editions of the same book, hardback or paperback, first print or a reprint, even re-editions where the title has changed. xISBN's linkages are determined algorithmically, based on the concepts of the Functional Requirements for Bibliographic Records.
- Related ISBNs from LibraryThing's thingISBN service. Works like xISBN, but based on the collective intelligence of LibraryThing users, who "combine" and "separate" books to create "works." thingISBN is less complete and weaker on library editions, but stronger for many paperbacks and non-English books.
