The Canon Law collection contains approximately 18,700 volumes that are located in the Canon Law Library, Mullen Library stacks, and the Rare Books/Special Collections Department. Some Eastern Church canon law can be found in the Semitics/ICOR Library. The collection is one of five major collections in the United States. Approximately a third of the collection was printed before 1800. The call number system at Catholic University is a modification of the Library of Congress call number system. ‘BV’ specifies Canon Law and ‘K’ specifies civil law.
Most reference material in Canon Law can be found in the Canon Law Reading Room (non-circulating). Access to this room is limited to Canon Law students. Check the WRLC catalog for material that could be applicable to your topic.
