In order to accommodate the growing number of books being published each year (last year alone more than 195,000 new titles and editions were published), beginning January 1, 2007, all 10-digit International Standard Book Numbers (ISBNs) will be converted to new 13-digit ISBNs.

As the United States ISBN Agency, Bowker is excited to introduce the new 13-digit ISBNs into BooksInPrint.com and GlobalBooksInPrint.com.

You will now be able to search by both the 13-digit ISBN and the 10-digit ISBN (either with or without hyphens). Additionally, the ISBN-13 will appear on the full description page for every title with an ISBN-10. If you accidentally type in a 13-digit ISBN that is not valid, BooksInPrint.com and GlobalBooksInPrint.com will automatically alert you of this error.
