Sensei's Library

Sensei's Library (commonly referred to as SL among Go-players) is an Internet website and wiki, dedicated to articles about, and discussion of, the game of Go. It was started in September 2000, by the Go players Morten Pahle and Arno Hollosi.^[1] Hollosi is also known for designing version 4 of Anders Kierulf's popular SGF file format and for his work with the Austrian Citizen Card project.^[2][3]

Sensei's Library is used for a number of purposes, and contains over 26,000 pages ^[4] on a wide range of topics, such as the culture and history of Go, Go theory, strategy, and community information. It is highly regarded in the Go community.^[5][6][7][8] One reviewer noted that as "a collaborative resource written by contributors, Sensei's Library may be the most extensive Go resource on the web. Articles cover a variety of topics, including possibly the best discussion of endgame theory published anywhere."^[5] Among its contributors are some published Go authors, such as Charles Matthews and John Fairbairn.^[9][10]
