I went to post the book P.K. the Great by Colleen L. Reece, ISBN #0828005605, and the search brought up the same ISBN--but matching a book called The Complete Illustrated Guide to Plants (Bible Plants and Animals Series).  I actually have that particular book, so I pulled my copy out and checked the ISBN--it's actually 0828005001, and a search for that ISBN on here does bring up the right title.  So The Complete Illustrated Guide to Plants is on here twice, once under the right ISBN and once under the wrong one.  How do I go about trying to get this straightened out so I can post P.K. the Great with the right ISBN/title match?

Destiny - You may want to contact the Team. Just scroll down and under 'Company', click the Contact Us link. Then click on 'Send Us Feedback' and explain the situation there.

A search of the web shows both titles listed a number of times for that ISBN; Amazon lists it as the plant book, so PBS is very unlikely to make a title change here.  It is possible that the publisher recycled an ISBN for a different edition of the plant book than the one you have, Destiny.

So, you'll want to post your copy of P. K. the Great as a non-ISBN item, as per the instructions in the Help Center.

Thanks, looks like that's what I'll do.
