APS offices and Library are closed Wednesday, February 20 due to inclement weather. 


The American Philosophical Society Conservation Department preserves the legacy of the past so it can speak to the future.

The Conservation Department provides complete collection care for all books, manuscripts, photographs, and works on paper and parchment held by the APS.

This is done through the work of professionally trained conservators who have a broad range of knowledge in history, art, and science.
