This page allows users to search multiple sources for a book given a 10- or 13-digit
International Standard Book Number. Spaces and dashes in the ISBN do not matter.
Wikimedia page containing links to catalogs of libraries, booksellers, and other book sources
This page links to catalogs of libraries, booksellers, and other book sources where you will be able to search for the book by its
International Standard Book Number (ISBN).
If you arrived at this page by clicking an ISBN link in a Wikipedia page, you will find the full range of relevant search links for that specific book by scrolling to the find links below. To search for a different book, type that book's individual ISBN into this ISBN search box.
Spaces and hyphens in the ISBN do not matter. Also, the number starts after the colon for "ISBN-10:" and "ISBN-13:" numbers.
An ISBN identifies a specific edition of a book. Any given title may therefore have a number of different ISBNs. See
#Find other editions 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. Check to see if the book exists or not.
Google Books and Amazon.com may be helpful if you want to
verify citations in Wikipedia articles, because they often let you search an online version of the book for specific words or phrases, or you can browse through the book (although for copyright reasons the entire book is usually not available). At the
Open Library (part of the
Internet Archive) you can borrow and read entire books online.

If the book you are looking for is in a language other than English, you might find it helpful to look at the equivalent pages on other Wikipedias, linked below – they are more likely to have sources appropriate for that language.
The WorldCat xISBN tool for finding other editions is no longer available. However, there is often a "view all editions" link on the results page from an ISBN search.
Google books often lists other editions of a book and related books under the "about this book" link.
