In the last three days I've gotten requests for books I don't have, and have never had, namely, Hamlet and The Lord of the Rings.

Is this some kind of a computer glitch -- these books are clearly not on any of my lists?

And now I'm more confused...  I found one of the physical books (Lord of the rings) even though it doesn't appear on my PBS Bookshelf.  Am I looking in the wrong place (My Account/My Bookshelf)?

I think I've figured it out.  I learned that "You will not see the book on your bookshelf when it is actively involved in a request."  I've now located the two physical books that were requested.  Too bad I cancelled one request.

You're too quick!

For future reference, here a help doc: I got a request for a book I don't have!

One thing that helps me when I receive a request and don't recognize a book is to look at the tranaction on my My Account page.  Over on the right, it will show the date I posted the book.  I then go to my bookshelf, sort it by "date", and look for other books I posted on the same date.  Often that's enough to jog my memory.

I've gotten requests before where I was like "I have that book?" but there it was. Our memories are getting old, lol. 

I once posted a book that I know I had.  When it was requested I couldn't find it.  I went through all my books several times, my bookshelf of books I want to read (I'd already read that book), and several other places.  I waited several days and finally had to cancel the transaction.  Never did find the book either.  Glad you found at least one of them.  Pat

I've cancelled a couple now after looking at every single book I own and not seeing it anywhere only to find it some time later on the very same shelves I scoured repeatedly.  I try to keep all my posted books together but I swear they rearrange themselves when I'm not looking.
