The Catholic University of America

We are updating our library system! Please take note:

  • The original plan was to go live with the new system July 18; however, problems have been encountered. We currently expect the new system up by July 25. Some services remain limited until the new system goes live.
  • Do not renew books in My Library Account. Do not worry, as overdue fees will not be assessed during this period!
  • Do not place CLS requests.
  • Mullen Library's hours of operation will not be affected during this period. Items may be checked in and out as usual at the Circulation Desk.
  • Please contact Access Services with any questions at 202-319-5060 or
