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.

Updated: American Philosophical Society Response to Novel Coronavirus COVID-19

Updated June 8, 2020, 8:00 a.m.

Dear APS Members, Friends, Researchers, and Visitors, 

In an effort to safeguard the health and safety of members of the APS community, the Society is undertaking strong social distancing measures to help slow the spread of novel coronavirus COVID-19. On March 19, Pennsylvania Governor Tom Wolf has ordered all non-life-sustaining businesses to close their physical locations. The APS, including offices and the Library, will be closed until further notice. We continue to monitor the situation and any further updates will be posted to this page. 

Response from APS Members

During the extraordinary times of the COVID-19 pandemic, APS Council has passed a rare public resolution on behalf of the Membership calling on Congress to enact a National Defense Education Act for the 21st Century. Read the statement that has been sent to the bipartisan leadership of the House and Senate.
