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 dashes 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 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. Check to see if the book exists or not.
The master copy of this page is located at Wikipedia:Book sources.
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.
You can 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 using xISBN. xISBN's linkages are determined algorithmically, based on the concepts of the Functional Requirements for Bibliographic Records.
