I just came into a LOT of vintage "pulp" paperbacks - many of which I will keep for their AMAZING cover art, but many MORE of which I can "let go" (I've listed just one rto see what happens - check out "Blow Desert Wind" onmy bookshelf).  Has anyone else ever tried listingthese sort of books?

I've listed a quite a few vintage YA and children's books in the past.  A few of them were mass market paperbacks from the '50s and '60.  I have listed hundreds of books that were too old for ISBNs and a lot of them have been taken.  Just make sure that they actually meet PBS condition requirements.  (I have quite a vintage readers that have stains on the pages so I can't post them.

I have also listed quite a few vintage paperbacks and had a lot of them requested.  I would suggest that you check in the "advanced search" function here by author/title  because this book may have been listed pereviously by somebody (ususlly already requestd, too) and you can "piggyback" on this previous listing. and not have to go to all of the trouble of the no ISBN# listing.  You have to makesure that the previous listing is of about the same age and by the same publisher, etc., but often that saves a lot of time.
