Stanford encyclopedia of philosophy
Stanford Encyclopedia of Philosophy (SEP) is designed so that each entry is maintained and kept up to date by an expert or group of experts in the field. All entries and substantive updates are refereed by the members of a distinguished Editorial Board before they are made public. Consequently, this reference work maintains academic standards while evolving and adapting in response to new research. You can cite fixed editions that are created on a quarterly basis and stored in the Archives (every entry contains a link to its complete archival history, identifying the fixed edition the reader should cite). The Table of Contents lists entries that are published or assigned. The Projected Table of Contents also lists entries which are currently unassigned but nevertheless projected.
