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 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 contains administrative records of the Association Saint-Jean-Baptiste branches in Stoney Point and Windsor, Ontario, ca. 1914-1967.

It is arranged in six series: Series I (Administrative Records, 1915-1967) contains letters patent and membership lists; Series II (Minutes, 1914-1967) contains meeting minutes from Stoney Point and Windsor; Series III (Correspondence, 1948-1967) contains correspondence files from the Windsor branch that touch on matters including financial arrangements, events, and activities; Series IV (Newsletters, 1957-1961) contains copies of the Bulletin that was a precursor to the Le Rempart newspaper; Series V (Commemorative Booklets, 1958; 1962) contains two publications celebrating significant community events; Series VI (Scrapbook, 1918-1919) contains a scrapbook of French-language children’s columns from local newspaper La Défense.

This fonds contains photocopies and translations of primary and secondary sources, as well as a small body of original notes and research correspondence, accumulated or created by Michael Power in the later 20th century, in the course of preparing three books and an article on aspects of Assumption College history. Series I contains materials documenting the early history of Assumption College and the role of the Basilian Fathers therein, particularly correspondence but also financial records, legal documents and legislation, histories and biographies. Series II contains biographical information and a few photographs related to the winners of the annual Christian Culture Gold Medal awarded by Assumption College as part of its long-running Christian Culture speaker series. Series III contains research material gathered in preparation for a short article about Rev. E.C. LeBel, a former president of Assumption University and first president of the University of Windsor. Some material duplicates original documents found in other AC fonds; some material comes from other archives or published works. It has been retained for its research value as a curated collection.

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 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.
