Identifiers from Bowker — including ISBNs, barcodes, and SANs — make book marketing and distribution more efficient for booksellers, libraries, universities, and wholesalers.
ISBNs
Make your book easier to discover
ISBNs are the global standard for identifying books. They simplify book distribution, inventory tracking, and purchase, and improve the chances that a book will be found and sold. An ISBN identifies one specific version of a book; each version of a book, print or digital, requires its own ISBN.
