The Historical Society of Pennsylvania (HSP) is pleased to announce that it has been awarded a grant from the Andrew W. Mellon Foundation in support of its Hidden Collections Initiative for Pennsylvania Small Archival Repositories (HCI-PSAR). HCI-PSAR is a three-phase project to make better known and more accessible the largely hidden collections of the numerous small, primarily volunteer-run archival and manuscript repositories throughout Pennsylvania, including small historical societies, museums, historic sites, and other institutions.
