And I read about what to do from The Librarian. I PMed the person and let them know about the problem. My question is, am I also supposed to mark the book received with a problem? Again, I already PMed the person, but I'm not sure if I'm supposed to mark the book RWAP or just wait.

Short answer is yes. Mark it RWAP and use the dialog that comes up to alert the sender (politely) and ask that your credit be returned. Just out of curiousity, was it a competely different book or a different binding, or...?

Thanks Patrick and Chris. It was a completely different book than the one I requested.

No!!

You should not mark the book as received until you have heard from the sender.

If it is a mix-up in the shipments of the books and they sent you someone else's book and them yours, then the sender is supposed to work with the two of you to get them straightened out, usually by buddying a credit for postage and PMing the address to send them on to.  The two receivers only mark the book as received when they actually get the book they requested.

If it is not a mixup and they just sent you the wrong book, you can discuss getting the correct book.

really the only time you should need to use RWP-wrong book is if one of the 4 points (ISBN, Title, Author, Binding) don't match or if they send something like an ARC or a regualr print for a Large Print order.

No, absolutely do NOT mark the book as received.  You did not receive the book you ordered, you shouldn't mark received until you get the right one.

From the Help Center

• Wrong Book
  • This includes inappropriate items such as ARCs or leaflets/pamphlets/booklets without ISBNs
  • This includes the wrong versions of books (ie, the ISBN, title, author or booktype of the book you received doesn't match the PBS listing of the book you requested)
  • This includes regular-font books when you requested a Large Print book
  • If you received a title you did not request, you can PM the sender as described in I received a book I didn't request!
    • this may have been a mixed-up request and can be easily rectified.
    • You don't have to mark the book received with a problem before sending a PM in this situation.
  • How to tell if the book you received is a "wrong book"

Don't mark it RWAP--you didn't receive it!

Chance are the person mixed up 2 orders. When this has happened to me, the sender offered me and the person who received my book  a credit in order for us to send the book to the right person. When we each got our book (which we both did) then we marked our books received :)

Awww crap. I marked it RWAP after the first post said to do so. :(

There is constant argument about this. Some say you should mark it Wrong Book Recieved. 

To me that option is for when you receive the wrong binding or ISBN # because how can you mark the book received if you got a completely different book? Or I should say how can you mark a book you don't have as being received?

What confused me was one of the options was he can refund my credit, but what credit if I didn't mark it received? So I asked here. Hope I didn't mess things up. Guess I'll just wait for his response?

"Some say you should mark it Wrong Book Recieved."

"Wrong Book Received" seemed pretty clear to me at the time. I apologize; after re-reading the Help section, it appears I've mispoken, but I'll point out that marking it RWAP in no way obviates any communication or resolution;  it opens an official line of communication where all are aware this might be looked at by the Powers That Be. Not necessarily a bad thing.

Anyway, my apologies - but I don't think you're doomed or anything if that's any consolation. Note that the Help section says "you don't HAVE to mark the book RWAP", not that you can't or shouldn't:

"You don't have to mark the book received with a problem before sending a PM in this situation."

So I really think you're ok, regardless - but sorry for any hassle.

Well, one big difference is that if you mark the book "RWAP", you only will get your credit back if the sender chooses to refund your credit.

If you receive a totally different book than the one you ordered, you should PM the sender, but you shouldn't mark it received (unless/until you receive the correct book). If you don't receive it in the mailing timeframe, the book will automatically go "lost" and you will automatically get your credit back. And, if/then you receive the correct book, you can go into your Transaction Archive and mark it received, transferring your credit back to the sender.

Yep, what Sara said.  You're not wrong for marking it as received, hopefully the sender makes things right for you and gets you your book or refunds your credit.

Not marking it received I think gives the sender the incentive to make things right and get you the correct book if they maybe weren't inclined to do so in the first place.  They won't get the credit until you mark the book as received.  You've now given them credit for sending you the wrong book.  Most of the time, the sender will make it right but there's no guarantee.
