The Cambodia Tribunal Monitor has frequently updated news and information on the ongoing trial of Duch, the former warden of S-21 prison, including video of the court proceedings.

The Documentation Center of Cambodia has a great deal of information on Tuol Sleng and on the Khmer Rouge in general. This site has photographs of many of the victims of S-21, the same photos that are on display at Tuol Sleng today.

The Virginia Quarterly Review has poetry and artwork by Robert Shultz and Binh Danh, inspired by Tuol Sleng.
