A while ago I mentioned BookCrossing.com, where you release your books into the wild and track thier movements. It's wacky but the concept appealed to me. It clearly appeals to a lot of other people, as they claim 353,948 books registered to the site. That's a lot of dead tree.
I released sixteen books in Ireland, and I haven't really had a results. This isn't surprisingly because these sort of, er, New World ideas don't play very well in Ireland.
I was reminded of BookCrossing when I read a fellow Vancouverite's weblog, where she mentions that she recently found a released book.
