One practical note before you go
Most circulation desks close fifteen minutes before the library closes, so plan a little earlier if you need to check out or return something. That’s the kind of detail that turns “I’ve got time” into “why is the desk already gone?”
- UT catalog information says most circulation desks close 15 minutes before the library closes.
- This matters most if you need staff help, checkout, or borrower services right before closing.
- For the most current status, use the live UT Libraries hours page on the day you go.
