But PBS won't let me list duplicate books to my shelf.  Do I just have to wait until the other w/l book is requested and then list the 2nd one?  Or is there a way to list them both now?

Thanks.

You will have to wait until the other is off of your shelf to post the second one. If it is wishlisted, it shouldn't take too long.

I think you need to wait.

Thanks.  I just checked out the help center (yes,  I should have done that beforehand, oops) and it says  I need to wait until the first one is mailed.

Thanks everyone.

also, if you buy a copy of a book on your TBR shelf you will have to add it back to the TBR list because it assumes you have read it and are posting it from that list, not posting another copy of that book.  However, you don't have to wait until it is mailed to relist it on your TBR shelf.
