Papers of William C. McInnes, SJ, documenting his life and work as an administrator, business ethicist, university professor, and Jesuit priest.

These include administrative records created as chaplain of the Boston College Alumni Association and as a participant in the work of the Institute for Lifelong Learning and the Center on Aging and Ethics at Boston College. Additionally, articles, book chapters, and book reviews pertaining to business ethics document his scholarship as a faculty member of the Boston College School of Business Administration in the early 1960s, while teaching and curriculum development materials documenting the same are from later in his career.

Personal material aggregated during his life and career form another portion of the papers, including biographical sketches, resumes, bibliographies, genealogical information, and photographs of family and vacations. There are also photographs of adjacent professional trips as president of the Association of Jesuit Colleges and Universities (AJCU). Other materials document McInnes's involvement with alumni activities and reunions for Boston College and Stern School of Business, New York University.

McInnes's work as a Jesuit priest included participation in Jesuit projects and leading retreats throughout his career, for which he kept extensive notes, sermons, and transcripts of speeches. He also kept notes and collected resources about sacramental rites and liturgy, including for baptisms, marriages, penance and reconciliation, and funerals.
