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.
