APS buildings are open to staff and invited guests. The Library is undergoing a renovation project that will make many collections inaccessible. It is expected to be completed in early 2022. 

Conservation

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.
