This fonds principally contains records connected with the Congregation of St. Basil (Basilian Fathers) whose members administered Assumption College and Assumption University from 1870 onward. Secondarily, it contains varied records that document the history of Assumption and its evolution over time. Included are legal documents, memos, correspondence, ephemera, constitutions and rules, historical narratives and memoirs, reports, and a variety of Basilian publications and formal histories of Assumption. Some items pertain to Catholic education broadly, or to the history of the Catholic Church in Southwestern Ontario. Of special note are Assumption fight songs and a victory song, and the Second World War war diary of Rev. Mike Dalton, a military chaplain.

This fonds contains records of students and student activities at Assumption College and Assumption University, ca. 1870s-1980s. It also includes some records from Assumption High School in that period, and for the University of Western Ontario during the years of Assumption’s affiliation with Western. Included are roll books and testimonials; minutes of the Literary Society; newsletters, yearbooks, and student publications; handbooks for students, residents, and faculty; promotional and recruitment brochures for Assumption; ephemera relating to special events, convocation, dramatics, and athletics; program and course listings; and news clippings. There is a small amount of material relating to student grades or schoolwork, alumni, Second World War servicemen, and deceased Basilian Fathers. Of special note: correspondence relating to the Assumption victory song, a history of Holy Names College, and brochures for 1940s summer school offerings listing Wyndham Lewis and Marshall McLuhan as faculty.

This fonds contains records connected with 22 Superiors or Presidents of Assumption College and University, ca. 1861-2009. For the most part it is organized chronologically by individual, although later accruals to the fonds have led to some quirks in file numbering or arrangement. Much of the fonds consists of administrative correspondence connected with institutional matters. There are also photographs, reports, publications, statistics, and notes on various subjects.
