As of July 6th, APS offices are open to staff and invited visitors. The Society will remain closed to the public for at least the rest of the summer. 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 summer and 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.

Lunch at the Library

Lunch at the library

The American Philosophical Society hosts a spring and fall series of informal lunch presentations on new research and emerging topics by and for APS staff, research fellows, and other scholars. From the U.S. Constitution to 18th-century French mathematicians, the topics are as varied as the research interests and collections at the APS.

Lunch and the program are from 12:00 to 1:00 p.m. in Benjamin Franklin Hall (427 Chestnut Street, Philadelphia).

APS Lunch at the Library invitations are available to Friends of the APS who contribute at the Supporting Circle and beyond ($500+). Registration is required. RSVP to Adrianna Link at
