An ISBN (International Standard Book Number) is a 13-digit number that identifies one specific edition and format of a book.
Paperback, hardcover and eBook are different products, so each format has its own ISBN.
Bookstores, libraries and distributors use it to list, order and track your book.
The ISBN is linked to your title, author and description. See book metadata.
