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 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.

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.

Much of the fonds consists of administrative correspondence connected with institutional matters. There are also photographs, reports, publications, statistics, and notes on various subjects.
