I have a ton of books that are just old paperbacks. They have been through many readers and are still readable. How can I offer them? Betty

If they are postable then you can just do that. If not, you can post a thread in the Book Bazaar with the titles you have. This usually works best if  you are running a deal (3 for 1 credit) or offering them free with an order from your shelf. Some genre forums have threads where you can post deals. (This varies by forum, so make sure you check out whether each has such a thread. People tend to get very testy if you don't follow the etiquette rules on that.)

Take a look at the postability guidelines here:  http://www.paperbackswap.com/help/help_item.php?id=205

If any of your books fall within the guidelines you can post them.  If not, you can offer them as freebies.

Thank you all very much...I am new and just learning about the club.
