Has anyone checked out the PaperBack Swap? A friend recommended it to me and so far it is fantastic! You post books (paperback and hardcover) you no longer want and ship them to people who do. You then can choose books from others and they send them to you.
You get 2 free book credits for signing up and posting 10 of your books. You then get one for every one you send out. There are a few genealogy books and a lot of history and travel ones. I think we need to get more genealogy books up there! There are a lot of people who have them on their wishlists...
If you do sign up, please use me as a referral and ask me to be a buddy: amandaea129
Enjoy the inexpensive books and helping the environment!
