ANSWER
Different UF libraries close at different times, so the answer depends on which building you mean. Library West currently closes as late as 1 a.m. on most weekdays, while Marston Science Library is 24/5 and closes at 10 p.m. Friday night before reopening Saturday morning.

Turn the answer into your next step
- Check the UF Libraries shared hours calendar before heading out, especially during holidays, breaks, or semester changes.
- If you need late-night entry after 10 p.m., bring a valid active UF ID or Santa Fe College ID.
- If you meant one specific branch, name it so the closing time can be pinned down exactly.
Library West
Library West’s posted hours on the UF Libraries shared calendar show it closes at 1 a.m. Sunday through Thursday, 10 p.m. on Friday, and 6 p.m. on Saturday. After 10 p.m., building access is limited to users with an active University of Florida ID or Santa Fe College ID.
- Use this if you’re heading to the main west-side study spot late at night.
- The after-10 p.m. access rule means not everyone can enter once the building is in late-night mode.
- Check the shared hours calendar before you go, since holiday and break hours can change.
Marston Science Library
Marston Science Library is posted as 24/5, which means it stays open continuously from Sunday at 10:00 a.m. until Friday at 10:00 p.m., then opens Saturday from 10:00 a.m. to 6:00 p.m. The same calendar notes that access after 10 p.m. is limited to users with an active University of Florida ID or Santa Fe College ID.
- Best fit if you need a round-the-clock study building during the week.
- Friday night is the hard stop: it closes at 10 p.m. and does not stay open overnight into Saturday.
- Holiday periods and semester breaks can change the pattern, so the shared calendar is the final check.
Other UF library locations
Smathers Library is shown on the UF Libraries hours calendar as 9 a.m. to 5 p.m. Monday through Friday, with weekends closed. The UF Libraries homepage also points users to the shared calendar for current events and branch hours.
- This is the simpler daytime-only option if you only need standard business hours.
- The main UF libraries page and the shared calendar are the right places to confirm current branch hours.
- If you meant a different branch, the closing time may be very different.
