I have a book that the ISBN pulls up another book in this database.  understandable, older book.

I put in the title and found the book (same author, pub date) but an ISBN that doesn't match (this is a sihoutte romance, won't be a hardcover vs paperback issue).  The book is New Boy in Town by Dorothy Francis, even Amazon uses a different ISBN (and I think it is the same one in this system)

I think I should post it as if it doesn't have an ISBN, but part of me says list it under the book that is already in the system.  I looked through the help files (and probably missed it) but would love some guidance on this.  Thanks!

There's an item in the Help Center called "Solutions to Common Book Posting Problems". Here's what it has to say about this situation:

Problem: the ISBN brings up a Listing Preview showing a totally different book than the one you have:

Explanation: This happens when publishers assign ISBNs to more than one title.  

On PBS, only one book listing can be attached to each ISBN. The one you are seeing on the listing preview is the one attached to that ISBN at PBS.

Solution: You will need to post this book with a customized listing for the book, using the Post Books without an ISBN link on the Post Books page.

What about when the same book and publishing date is listed on Amazon with a different ISBN? 

Or what about the listing in PBS for the same title/author/pub date?  If it is the same book but different ISBN, do I need to post as if there was no ISBN?  It seems crazy to list the same book twice when the likelihood of it actually being published under 2 ISBN's is slim (this is NOT a book that would have a hard cover and paperback)

The point is that the listing you use for the book needs to describe the book properly to requestors.  Someone else requesting a book you posted as a paperback may be unhappy with a hardcover and vice versa.

When you post a book, it asks you to match the title, isbn, author and binding type. All of those need to match.  If they don't you need to make a listing for your book that matches in all four aspects.  Those are the only things that requestors can "count on" when they request a particular book.

Yes, but I think what the original poster is asking is, if it matches Title, Author, and Binding, can you post it under the 'wrong' ISBN? If everything else is the same. Especially in cases where the ISBN on your copy's been poached by the publisher.

YES exactly!  There is NO WAY there is a hard cover of this book.  It is a romance book (like Harlequin) and everything else matches except the ISBN because it is so old.  When I looked the book up on Amazon, the ISBN matched what is here on PBS with the same title, author, etc.

Your first instinct is correct. You must list it as if it did not have an ISBN. All four questions must be yes, to list it with that ISBN. If the book does not have that ISBN on it, then you cannot list it using it. Unfortunately the publishers use the same ISBN for multiple editions of a book, I have one that the same ISBN is not only on the trade size, the regular pb size, and the hardcover, but it is also on the omnibus book that contains the first two books in the series!!! Now how dumb is that!?!?!

Only the first book entered into the database gets to claim the ISBN, the other versions must all be listed as if they were non-ISBN books. This is why, when looking for a book or putting it on your WL, it is a good idea to search for it using the title NOT the ISBN. Hope that helps you.
