i have the books but the codes don't match what can i do?

if your isbn is the one that is wl you can post in the bazaar that you have ________ book that is wl under ______isbn. and once you post it, it will send out an email to all wishing members that an alternative format is availalbe

advertise them in the book bazaar...i do believe there is a thread for that...

This is the same advice you got when you posted almost the same question at 2:48pm today...the recommendations aren't going to change.

You can post your book with your ISBN. Depending on the email settings of the person wishlisting the book they may get an email notifying them that "a book similar to your wishlisted book" has been posted. The email also contains a link where they can go see if the book is an acceptable substitute for the ISBN on their wishlist.

I had a book one time that had 80+ people WLing a different ISBN. The books were identical except for ISBN-same cover, number of pages, etc...,  There was one other copy of my version in PBS.  I tagged the WL version w/the ISBN of the one I had. I tagged it like "2 posted under ISBNXXXX"  Mine was ordered within a couple hours so I can only assume the 1st one was also ordered. 

Check to make sure your versions are the same binding.  Sometimes people think they have WL books when there's lots of copies of their version available.  That happens a lot if people are WLing large print or audios.  If you have a paperback that's readily available-then those people really want the lrg print or audio version.  So you might want to check out how many of your ISBN are available on PBS already.
