paperbackswap.com

It's a great site. I've been on it for almost a year and have absolutely no complaints. The site is very well designed and it's easy to keep track of what you have coming in and going out. The book selection is getting larger all the time, and if they don't have something you want, you can put it on your wishlist.

I've been on paperbackswap.com for a little over a year. It's great. So far, I've received 84 books and sent out 73. I haven't had a bad transaction yet. There was one that went lost, but once it was marked as lost I was put at the front of the line for the book and received another copy shortly thereafter.
