“If the heart of the University is in scholarship, then the heart of scholarship is in the library,” pronounced Rev. Dr. Peter Guilday, Professor of American Church History, at the April 25, 1925 cornerstone laying ceremony for the John. K. Mullen of Denver Library. 

Inspired by Guilday’s words, a display will be held in the May Gallery from now and through summer 2025 on “The Heart of Scholarship: 100 Years of Mullen Library.” A reflection on the place – both literally and figuratively – of Mullen Library on the campus, this exhibit celebrates the centennial of the April 25, 1925 cornerstone laying of the Library, the building’s construction, its staff and students, and its role in the life of The Catholic University of America.
