Just theories here:
The same book re-issued by another publisher might have a different ISBN. A book with an insert (e.g., CDROM) may have a different ISBN, but be the "same" for some purposes. And mistakes can be made... Ultimately, I suspect that the uniqueness of ISBN to what normal folks call the "same book" is not as clear as one would hope. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/mysql?unsub=arch...@jab.org
