This page allows users to search for multiple sources for a book given the 10- or 13-digit ISBN number. Spaces and dashes in the ISBN number do not matter. In Wikipedia, numbers preceded by "ISBN" link directly to this page.
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).
Important: Google Books and Amazon.com provide valuable information about a book, but they might not give you the specifics you need. Consult the resources below for other ways to locate the source.
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.
These links produce citations in various referencing styles.
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.
