13-digit ISBN numbers
This world is converting to the new Bookland EAN-13, 13-digit, bar-code ISBNs. It handles only 10-digit ISBNs. There is a program online to convert 10 to 13. All it does is prepend 978- to the old number and recompute the check digit, e. g.
0-915972-22-0 becomes 978-0-915972-22-7.
0-13-625666-X becomes 978-0-13-625666-3.
The new Bookland EAN-13 checkdigit is computed in an unusual way with mod 10 and weight 3. This means the 13-digit ISBN numbers are always purely numeric. There is never an X checkdigit as there is sometimes with the mod-10, 10-digit ISBNs. 10-digit ISBNs and 12-digit UPC (Universal Product Code)s are being unified as 13-digit EANs.
