pSearch is a customized search engine dedicated to philosophy-related web pages. It is powered by Google Co-op and maintained by Joe Lau at the University of Hong Kong.
pSearch provides search results more relevant to academic philosophers by searching only those web sites with online academic philosophy papers and authoritative reference sites. The list of such sites (>1500) currently comes from two sources: (a) The list of sites from Online Papers in Philosophy which was started by Brian Weatherson and is now maintained by Jonathan Ichikawa. (b) David Chalmers' list of people with online philosophy papers. Their wonderful effort and service to the philosophy community made this search engine possible.
This site replaces The international directory of online philosophy papers which is no longer maintained.
