The Stanford Encyclopedia of Philosophy (SEP), an open-access dynamic reference work, invites you to join the Friends of the SEP Society. By paying modest, annual membership dues to join the Society, members will receive the following benefits: (a) download access to high quality PDF (Portable Document Format, a.k.a. Acrobat) versions of SEP entries and (b) quarterly email notifications (if you ‘opt-in’) that inform you when PDFs you've downloaded have been updated in the most recent quarterly SEP Archive. The SEP has a comprehensive PDF Library of its entries, and we generate new PDFs after each quarterly SEP Archive for those entries that have been published or revised during the previous 3 months. For more information, read About the Society.

We also release our PDFs in single-column half-sheets (5½ × 8½ in)—see the Sample PDF. You might find this format especially useful for mobile devices.

Members may get other member benefits as these become available.
