The Internet Encyclopedia of Philosophy

The Internet Encyclopedia of Philosophy (IEP) (ISSN 2161-0002) was founded in 1995 to provide open access to detailed, scholarly, peer-reviewed information on key topics and philosophers in all areas of philosophy. The Encyclopedia receives no funding, and operates through the volunteer work of the editors, authors, volunteers, and technical advisers. The Encyclopedia is free of charge and available to all users of the Internet world-wide. The staff of 30 editors and approximately 300 authors hold doctorate degrees and are professors at universities around the world, most notably from English-speaking countries. The purpose of the IEP is to provide detailed, scholarly, peer-reviewed information on key topics and philosophers in all areas of academic philosophy.

Stanford Encyclopedia of Philosophy

The Stanford Encyclopedia of Philosophy (SEP) has nearly 1600 entries online (March 2018). From its inception, the SEP was 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, our dynamic reference work maintains academic standards while evolving and adapting in response to new research.
