As of July 6th, APS offices are open to staff and invited visitors. The Society will remain closed to the public until further notice. Library & Museum staff now have access to our collections and will respond to reference and photoduplication requests as soon as possible. However, please note that response times may be delayed due to increased demand. The Society will continue a robust slate of virtual programs throughout the fall. Read more about virtual programming and resources that can be accessed remotely. For further information on the APS reopening and its COVID response, please click here.

Support the APS

“An investment in knowledge always pays the best interest.”

-Benjamin Franklin

The American Philosophical Society, this country’s first learned society, has continued to play an important role in American culture and intellectual life since its founding nearly 275 years ago. 

An eminent learned organization of international reputation, the APS promotes useful knowledge in the sciences and humanities through excellence in scholarly research, professional meetings, publications, library resources, and community outreach. 

Help us preserve the past and shape the future with a gift to the APS. Gifts from Members and Friends provide important support for the annual operations of the organization, as well as endowment, restricted programs, and capital needs.
