Help:ISBN
Many Wikipedia articles have an International Standard Book Number (ISBN) alongside the bibliographical entry for each book. Clicking on the linked 10- or 13-digit number links to WP:Book sources. This shows whether the particular book is listed in a library catalogue, at WorldCat, at Google Books, at major booksellers, or at other websites.
