Bookcrossing is an interesting web-based service that “sets books free.” Members leave books in public places, then track their progression around the community and world online. It may be little more than a curiosity but I find it surprisingly hopeful. It engages people’s sense of community by tapping the fascination with serendipity. It also, in some small way, engenders greater society-wide efficiency of resource use. Many people read the same book, then discuss its merits online.
