You probably have lots of old books locked away in a dusty box or under your bed; I know I did. Instead of keeping them hidden away, you can release them into the wild and give them a second chance at a new life! Its fun and you don't just release them, but you hunt them too! It's like a global treasure hunt, complete with release notes and journal entries.
For the less adventurous, Bookcrossing also has book clubs via mail and local meeting places for book trading.
It is free, it is fun and it encourages people to read...just try it!
