The Historical Society of Pennsylvania’s Hidden Collections Initiative for Pennsylvania Small Archival Repositories (HCI-PSAR) is a project whose goal is to make better known and more accessible the important but often hidden archival collections held by the many small, primarily volunteer-run historical organizations in the Philadelphia area. The project is funded by a grant from the Andrew W. Mellon Foundation.
On July 30, 2013, HCI-PSAR project staff surveyed the STHS archival collections. Here is their final report.
The final report contains the reports on four individual collections. Here are those reports for your convenience.
