Here's a great site for book lovers: BookMooch lets you post books you're willing to part with. People can then ask for them and you send them the books they want. Free. Out of the kindness of your heart. Well, you do get something out of it, of course. As you give books away, you earn points, and then you can ask for (or "buy") books from folks who are giving them away, too. Brilliant, eh? 40,000 members, too, so there's plenty to choose from. I'm wondering if I can get European paperbacks before they come out over here. Mwah-hah-hah!
Here's a NYT writeup, too. According to the article, BookMooch ain't the first to do this. Just the most neighborly. You can give away your points to other folks if you're feeling extra generous. Or you can donate them to worthy causes, like New Orleans libraries.
