The American Philosophical Association (APA) promotes the discipline and profession of philosophy, both within the academy and in the public arena. The APA supports the professional development of philosophers at all levels and works to foster greater understanding and appreciation of the value of philosophical inquiry.

The Internet Encyclopedia of Philosophy 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 it operates through the volunteer work of the editors, authors, volunteers, and technical advisers. At present, the IEP has over a million visitors per month and about 20 million page views per year. The Encyclopedia is free of charge and available to all users of the Internet worldwide. The staff of 30 editors and approximately 300 authors hold doctorate degrees and are professors at universities around the world.

PhilPapers is a comprehensive index and bibliography of philosophy maintained by the community of philosophers. They monitor all sources of research content in philosophy, including journals, books, open access archives, and personal pages maintained by academics.

Hosted on Stanford University's website, the Stanford Encyclopedia of Philosophy (SEP) organizes scholars from around the world in philosophy and related disciplines to create and maintain an up-to-date reference work. 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, this dynamic reference work maintains academic standards while evolving and adapting in response to new research.
