Wikipedia: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.
