ISBN
Are you ready for the 13-digit ISBNs?
If you haven’t noticed yet, the first of the 979-prefixed ISBNs (or EANs) are starting to be used. These ISBN numbers are the first 13-digit numbers that do not also have a 10-digit version. This means that your circulation system must use the 13-digit numbers instead of having the choice between those and the 10-digit. It is highly important that you and your library are prepared for these 13-digit identifiers.
Here are some important measures to take to ensure compatibility with the new 13 digit ISBNs.
- Make sure your library cataloging/circulation system can read and handle the 13 digit numbers. To do so either contact your technical department or cataloging/circulation system vendor.
- You should also update your systems, so they can store and search for titles using strictly the ISBN-13.
Basic ISBN Information:
The ISBN (International Standard Book Number) provides a standard way to identify books in global trade. On January 1, 2007 the book industry transitioned to 13-digit ISBNs, phasing out the use of 10-digit numbers.
Why did the ISBN numbers change?
The 13-digit ISBN numbers were developed to aide in the increasing shortage of available 10-digit ISBNs. It was also designed to help align the numbering system for books with the global EAN.UCC identification system.
