Holiday Schedule

We request that all visitors schedule an appointment so that we may better satisfy their research needs. This is especially important as some collections are stored off site and can take up to 72 hours to retrieve.

Please call 202-319-5065 to schedule an appointment.

The Catholic University of America is located at 620 Michigan Avenue N.E., Washington, D.C. 20064, and can be reached via the Red Line of the Metro rail Transit System at the Brookland/CUA station. The main office of Special Collecctions occupies part of Aquinas Hall on the University's campus; it is accessible via Room 101 of Aquinas Hall.


Parking on our campus is very limited and permits are required. Patrons who wish to obtain parking permits must make these arrangements through our office of Parking and Transportation Services.

We usually recommend that those who arrive by car use the metered lots at the National Shrine or in front of Mullen Library.

For general information about arriving to our campus, please see the University's Visitors main page.
