Edited by Edward N. Zalta, Consulting Associate Professor of Philosophy at Stanford, this site claims to be the first dynamic encyclopedia. Unlike standard reference works or CD-ROMS, each entry in the Stanford Encyclopedia is maintained and kept up to date by experts in the field. As a result, the entries and the Encyclopedia as a whole are responsive to new developments in the field. The Encyclopedia is still very much under development, with many topics awaiting an entry. However, regular users may track new additions via the What's New section. Additional resources include an internal search engine and an archive of the previous three editions of the Encyclopedia.
