Fiscal Year 2026 marks the first year in which the library has been able to utilize the generous gift of a devoted friend of the library, Rev. Msgr. Robert Trisco. In December 2020, Msgr. Trisco, Professor Emeritus of Church History, pledged $650,000 in support of the John K. Mullen of Denver Memorial Library and the advancement of scholarship in his field at The Catholic University of America. According to University Librarian Stephen Connaghan, this gift is “one of the largest endowments the library has ever received.”
I am pleased to share that, through this support, Mullen Library has been able to acquire a number of significant works in Church history, strengthening our collections in ways that reflect both the depth and breadth of Msgr. Trisco’s scholarly vision. These new resources not only enrich our existing collections but also open new pathways for discovery, teaching, and dialogue among students, faculty, and scholars.
We are grateful for Msgr. Trisco’s enduring commitment to scholarship, to the Church, and to the mission of the library. His generosity serves as a lasting reminder of the vital role that libraries play in preserving the past while equipping future generations to engage it thoughtfully and critically. It is an honor to continue shaping our collections in a way that reflects his intellectual legacy and supports academic inquiry for years to come.
We look forward to further expanding this collection in Fiscal Year 2027 and beyond. Please use the list below to explore the titles recently acquired through this fund. We welcome your suggestions and feedback. While the library actively monitors publications from major academic publishers, we especially encourage recommendations of works in Church history from lesser-known, international, or specialized presses, whose contributions are often invaluable yet less visible.
