I just signed up for www.paperbackswap.com as a new source to trade books. This site appears to be very organized, with tons of cool features to find books. At this time it is also free. How cool is that?
Basically you sign up, list 9 books and you will then get a 3 book “credit” that you can immediately use. What I found useful was the “wish list” feature. I searched the wish lists and found 3 matches with books I had here already. I am pretty busy and didn’t want to list all my books, so this way I now have my initial 3 book credit, plus I will get 3 more credits as soon as the books I ship out are received.
