We’ve updated our database of books and are ready to post just about anything. However, to make the club a pleasure for all our members, we cannot stress enough the importance of posting books with correct ISBNs. Many times a member may see a wish for a particular book. They have the book but it doesn’t exactly match the ISBN number. The member decides change the ISBN to match the wish list request. Please do not do this as it creates a lot of problems (and more feedback for us to answer). More times than not, there is a reason that the ISBNs don’t exactly match (hardback, paperback, condensed, unabridged, revised, etc.) Sometimes it is very important to the member “wishing” for the book that the ISBNs be the same. PLEASE DO NOT list books with incorrect ISBNs just to get a match on the Wish List. We are working on a system that will allow the “wishing member” to specify any and all versions of the book that will be considered acceptable to them as well as a way for you to notify the wishing member of a variation of the wish. Thank you to all members for helping to keep the ISBN system “clean” for PaperBackSwap.
