A while ago I linked to and posted about my love of Geocaching. Bookcrossing is just like this but with yep you guessed it... books. The concept is simple, once you finish a book and want to pass it on you can register the book on the site and leave the book in the wild. You can also search in your area to see what books have been left recently in charity shops, pubs, airports, tubes, buses and even your local parks.
If your interested and you have a spare 5 mins you can:
It takes a couple of minutes to register your details, name, address, you know the usual
There are currently 6,036 out there in the wild in Britain. It also includes Thailand, the USA and Ireland to name but a few.
I am yet to register a book (as I'm being a lazy reader and writer) but once I do I'll be leaving it somewhere for someone to find. Hopefully I'll find a novel racers work (not that I don't buy them already but it would still be cool to find one!)
