I used to sell books on the internet through half.com and alibris.com, but my inventory hasn’t been very profitable of late and I have a whole bookshelf of books that I don’t really need.

Enter Bookmooch.com. It works great. There’s a way to earn points by listing books to give away and actually sending them. Once you have earned points you can redeam them for books that other people want to give away. It’s a great system. I’ve made several trades already.
