The PACSCL Hidden Collections Processing Project

This project, conducted in two phases from 2009-2014, resulted in the creation of archival finding aids for more than 200 collections representing more than a linear mile of manuscripts, diaries, scrapbooks, photographs, drawings, and other materials. More than 30 PACSCL members, plus additional area repositories, participated in this project.

The finding aids have been aggregated via a database created as part of the project. This database has been augmented by PACSCL member finding aids created after (or outside) the project, as well as collection-level records created for the Hidden Collections Initiative for Small Pennsylvania Archival Repositories (HCI-PSAR), a project conducted by member library Historical Society of Pennsylvania with funding from The Andrew W. Mellon Foundation. As a reflection of PACSCL’s desire to have a comprehensive guide to archival research collections in the region, this resource has been renamed the Philadelphia Area Archives Research Portal and now provides access to descriptions of more than 5,000 collections in more than 200 area institutions.

Phases 1 and 2 of this project were supported by a Hidden Collections processing grant from the Council on Library and Information Resources (CLIR). The grant program is made possible by funding from The Andrew W. Mellon Foundation.
