The International Standard Book Number (ISBN) is a unique identifier for books, intended to simplify the distribution and purchase of books by providing a specific code for each title and edition. An ISBN is a 13-digit number (or 10 digits for editions that were published before 2007), which helps libraries, retailers, and consumers to distinguish between different books.
