ISBN-13 Goes Into Effect January 1
By the time Bookselling This Week returns from its holiday hiatus, the book industry's conversion to 13-digit ISBNs (International Standard Book Numbers) will already be in effect for four days. The January 1, 2007, switch from 10-digit ISBNs to 13 digits will have an impact on everything from publishers' catalogs, price sheets, and invoices to booksellers' ability to place and receive orders.
