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.

Visit the American Philosophical Society Museum from 12 - 3 p.m. on the second Saturday of the month this summer for free, hands-on activities geared towards families!

Create your own countryside or city and try your hand at surveying! Many tools helped surveyors accurately measure different landscapes, like the Gunter’s chain. Come see a Gunter’s chain in action and use a miniature version to measure your own landmarks. You can even discuss your mapping ideas with Charles Mason, of the Mason-Dixon Line!

Every second Saturday of the month, June through September, the APS Museum will have free educational activities for families, individuals, and all visitors to enjoy.
