This case study describes a recent exhibit of archival photographs at the University of Dayton and how it was used as a teaching tool in an undergraduate course. The exhibit, Faith, Reason, and One-Hour Processing, showcased archival photographs from the Marian Library, a special library on campus devoted to the Blessed Virgin Mary. This article outlines how the project was developed in conjunction with a campus-wide theme, Faith and Reason, and used as a teaching tool in an interdisciplinary undergraduate course, Development of Western Culture in a Global Context (ASI 120). This article also suggests the interdisciplinary potential of Catholic archival collections and several ways to leverage archival exhibits, including partnerships for promotion and curricular integration.
