BookMooch is an international online book exchange community founded by John Buckman in 2006.
Links to Amazon sites in various countries allow members to enter books into the system quickly.
He manages the site with the assistance of a small, international admin team who participate in the forums and resolve any issues.
A balanced ratio of mooching to giving must be maintained by each member to continue to receive books.
BookMooch is a for-profit corporation wholly owned by Buckman, but it does not charge membership or use fees.
