The Catholic University of America

Location and Hours

Aquinas Hall: CUA 

Monday - Friday 9:00am to 5:00pm
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. We will close for Christmas Break at 12 on Friday, December 19, and re-open at 9am on Monday, January 5, 2015.

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