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.
