Dear Colleagues, This is to inform you that a small website has been created for the purpose of collecting and distributing research devoted to algebraic set theory. Following on the Joyal & Moerdijk monograph by the same name, people in several different locations have begun pursuing related research. It is hoped that linking these efforts will encourage collaboration and make it easier for those new to the field to gain easy access. The site is located at: http://www.phil.cmu.edu/projects/ast/ We hope to make more of the papers listed in the bibliography available on the site soon, and to augment the listings with brief descriptions. Please contact me or "webmaster" Michael Warren <mwarren@andrew.cmu.edu> if you would like to have your name, homepage, and/or research listed. See (some of) you in Vancouver! Steve Awodey
