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.

Members’ Annual Fund

Archival item

The annual contributions of the APS’s elected Members and their families are critical to the operation of the Society. This support makes possible all of the APS’s core programs by helping to meet the costs of staffing, facilities, and administrative expenses. It would be impossible to carry on the day-to-day work of the APS without these charitable contributions.

The Members’ Annual Fund allows you to support more than one core program with a single gift distributed according to your preferences. As always, the APS welcomes unrestricted gifts, but you may also designate your annual contribution for the Meetings, the Library, the Museum, Research/Grants, and/or Publications.

Gifts to the APS are fully tax-deductible in accordance with the IRS code.

For further information, please contact Linda Jacobs at 215-440-3434 or
