The Episcopal Theological School (ETS) archives broadly documents the administration, governance, instruction, and community of The Episcopal Church’s seminary in Cambridge, Massachusetts before its merger with the Philadelphia Divinity School (PDS) to form the Episcopal Divinity School (EDS). The records include the Board of Trustees and Board of Visitors; extensive financial records; student matriculation and performance records; records of the Deans and faculty; records of the ETS chapel, alumni association, and student organizations; and publications such as the ETS Bulletin and Catalog. The archive features audio recordings of sermons and conference proceedings made during important ETS events, as well as photographs of graduating classes, buildings, and seminary life. The ETS Centennial, celebrated in 1967 with conferences, commemorative events, and a major capital campaign, is well documented.
