Organized in 1852, the Presbyterian Historical Society in Philadelphia is the oldest denominational archives in the United States. PHS serves as the national archives of the Presbyterian Church (U.S.A.) and exists to collect, preserve, and share the story of the American Presbyterian and Reformed experience with Presbyterians, the scholarly community, and the general public.
The society’s holdings include over 30,000 cubic feet of records from congregations, presbyteries, and synods from across the country, and from national agencies charged with overseeing Presbyterian mission work both in the United States and abroad. The PHS collection also includes personal papers and a library of over 250,000 titles germane to Reformed history from the sixteenth century to the present.
