This fonds contains financial records of Assumption College and University, ca. 1856-1999. These include general cash books, financial statements, correspondence, and records of accounts, as well as real estate acquired, constructed, maintained, or sold by Assumption and/or the Basilian Fathers in the vicinity of the present-day campus, from Tecumseh Road north to the Detroit River. Included are land deeds, contracts, and other legal documents, as well as architectural or schematic drawings and specifications for campus buildings. Notably, this includes records of property acquired in the early days of the college, and campus properties sold by Assumption in the 1960s to the University of Windsor. Of special note: a small number of 1950s-1960s records relating to Essex College, the non-denominational affiliated college that helped secure provincial government funding for the campus.

This fonds primarily contains personal papers, publications, and oral histories (ca. 1870-1984) relating to the Basilian Fathers who served as teaching staff for Assumption College and Assumption University. Included are diaries, notebooks, correspondence, memoirs, recorded interviews, memorials, manuscripts and published works. Of special note are the extensive papers of Bishop Leo C. Nelligan, records of O’Connor House, and a few records from Rev. Pierre Tourvieille. Secondarily, this fonds contains extensive administrative records documenting the history of Essex College, found in the papers of professor W.H. Arison.

This fonds contains records of students and student activities at Assumption College and Assumption University, ca. 1870s-1980s.

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.
