The John K. Mullen of Denver Memorial Library of The Catholic University of America is an integral component of the academic process, provides access to our cultural and scientific heritage through library resources and services and cooperates actively with the faculty and students in the teaching, learning and research process.

Centrally located on The Catholic University of America campus, the Mullen Library is also central to the work of the institution, and carries out its mission by serving as the primary resource for content-related materials to:

• meet the research and scholarly needs of graduate students and faculty members,
• provide users with access to materials located outside the immediate library system, and
• equip users with the skills and resources needed for continuous lifelong learning.

The Mullen Library organizes, manages, and preserves unique books and materials that serve as records of our Catholic intellectual heritage and culture through special collections including those in Rare Books/Special Collections, the Semitics/ICOR library, the University Museum Collection, and the American Catholic History Research Center and University Archives.

The Mullen Library also houses the collections of the Benjamin T. Rome School of Music, the School of Nursing/Department of Biology Library, the Department of Physics Library, and the Oliveira Lima Library.

The Judge Kathryn J. Dufour Law Library is housed in the Columbus School of Law.
