The International Standard Book Number (ISBN) is a 10-digit code assigned to books published after 1972 or a 13-digit code assigned to books published after 2006. Each ISBN is unique to a specific book. A different ISBN is assigned to hardcover and paperback versions of the same title, as well as later editions with changes or additional content, or editions produced by different publishers. You'll generally find the number printed over the bar code on the book's back cover or on the copyright page.
