Received a book today that was a hardcover, not as listed as a paperback.  And also it was from a library.  I accepted it into the system without a problem, but after I read it, how do I go in and change it to a hardcover?  And how do I list it as being from a library since some people do not like books from a library.

I did make a comment to PBS when I accepted the book into the system. 

Well ex-library books are allowed unless someone has an RC asking that they not be sent to them. So you can send it to whoever requests it from you as long as they don't have an RC saying no ex-library books.

ETA: I'm not sure about your other problem. I wasn't meaning to ignore it, I just don't know if you can change it. I've never had an ISBN not match the binding.

If it does not match the binding shown in the system, then you have to list it as if it did not have an ISBN. Apparently, occassionally  ISBN numbers are reused.

BUT, if it was listed as a paperback and you received a hardback it should have been marked RWAP -- wrong book. Just remember when you relist it to NOT use the current listing.

you cannot change the binding in the system.  Publisher's frequently reuse bindings-especially for library and book club editions.  you will have to post the book without an ISBN. PBS very rarely changes the binding in teh system.  you would have to prove to them that the book never existed in paperback and there would have to be no one wishing for hte book and no copies posted into the system under the listing the way it is now.  Did you check to see if the ISBN on your book actually matches the listing in your Transaction Archive?  Some people don't pay attention and post books by the picture and ignore all the prompts about things having to match.

This was a mistake by the sender who should not have sent the book. 

If the listing here is for one kind of binding (paperback in this case), and your book with that ISBN has a different binding, you can't post it to the ISBN.  You have to post it without an ISBN.  In this case, you could have marked the book received with a problem --> wrong book.  (Wrong binding is one of the "official" problems here.  You could have asked for your credit back.

Usually this happens because publishers have reused an ISBN for more than one binding,  Our PBS listing is for the edition of that ISBN that was posted here first.

There's a good help doc on this called "Solutions to Common Book-Posting Problems."

Edited to add: If you don't want former library books, you can add a "requestor condition" to that effect.

It's one thing that you have to check very carefully. In the past three days, I've listed four trade paperbacks that the ISBN here reflects a hardback.  I hated to list them all without an ISBN, but there's no option. It's especially easy to overlook it if you are listing a file of ISBNs or 20 books. I now sort and list only pbs or only hardbacks if I'm listing in either of those ways as it's easier to catch if one shows up incorrectly.  

Jodi make sure your tradesize books aren't Advanced Reader's Copies.  Sometimes when a tradesize comes up as a hardcover it's because it's an ARC.  Those aren't postable on PBS.  you can still ask a credit for them but you have to offer them in the Book Bazaar or genre threads.

I've noticed that it's very common for book clubs to issue hardcovers with the paperback ISBN or an ISBN that brings up no book or a completely different book.
