Here's an idea I wanted to pass along. A friend introduced me to the idea of BookCrossing. It works like "Where's George?", and basically, you label your books with a sticker tag leading back to the BookCrossing site and leave your used books in public places for other people to discover (and hopefully, read).BookCrossing lets you share your books with the world, and track their individual journeys forever more. Our members have registered 2,306,208 books so far, and a good number of these are "in the wild" at any one time. The links here cover just about anything you might want to do with a book here on our site.
If you're lucky, your book finder will log in to BookCrossing and "journal" their find.
I haven't started yet, but with all the paperbacks in my house just taking up space, I'm considering it. Anyone else?
