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.
