About the PTS Archives

The Pittsburgh Theological Seminary is the result of several mergers following the founding of its earliest antecedent, Service Seminary, in 1794 by the Associate Presbyterian Church. The documents recording those mergers as well as the records of seminaries past and present, are housed in the Pittsburgh Theological Seminary Archives. 

The primary purpose of the Pittsburgh Theological Seminary Archives is to provide for the efficient and systematic control of the creation, receipt, maintenance, use, and disposition of records. Records administration covers the management of records, regardless of age, to meet the administrative, financial, legal, and historical needs within the Pittsburgh Theological Seminary’s offices and departments. 

The PTS Archives contains Seminary and antecedent seminary institutional records, manuscript collections, personal papers, photographs, and artifacts. Other materials housed in the Archives document the histories of the Associate, Associate Reformed, United Presbyterian, and Presbyterian (U.S.A.) congregations, synods, and general assemblies.
