As many of you already know book publishers began shifting from a 10-digit ISBN to a 13-digit ISBN earlier this year. Starting next week eBay and Half.com will begin supporting the new 13-digit format, as well as the existing 10-digit format. This means that whichever format your book was published under, you should have no problem finding it on the site.

Changes to File Exchange Format
To accommodate this change we also had to make some changes to the File Exchange downloadable file format. If you currently use any of the File Exchange downloadable files, whether you sell books or not, you will need to adjust your formatting to accommodate an additional data column. A complete rundown of the changes, and answers to related questions, can be found on this thread on the File Exchange board.

Sincerely,
