Sensei's Library (short 'SL') is a cooperative website for Go players
of all levels. SL is based on an anarchic architecture called
WikiWikiWeb which allows all users to contribute to the site - no
username - no passwords.
Opened in November 2000, in today (May 2004) SL contains a wealth of
Go-related information and discussion with over 8700 pages, and the
contents are still growing.
Sensei's Library can be found at <http://senseis.xmp.net/>.
