Library West will be open 24 hours a day Sunday through Thursday in the spring.
The Student Senate unanimously gave the final approval to the bill Tuesday night.
SG will draw $59,174 from reserve funds to pay for the pilot project, which will run from Jan. 9 to May 4.
Senator Katie Waldman, one of the bill's authors, said after the meeting that if students use the library enough, the library and UF administration would find a way to continue funding the long hours.
SG might provide some future funding, but it would not cover all the costs, Waldman said.
The money will go toward paying the two library assistants, two student workers and two security guards who will be working during the extended hours.
Waldman said in her presentation that one of the security guards will be at the doors to the library to check students' Gator 1 ID cards starting at midnight.
She also said SG is working on the possibility of arranging after-hours transportation by Student Nighttime Auxiliary Patrol (SNAP) or Regional Transit System for students studying late at the library.
The basement and the first through fourth floors will be open, but Waldman said the fourth floor's hours will depend on how many students use it.
The library's sixth floor will be open for graduate students.
This semester, Library West is open from 8 a.m. to 1 a.m. Monday through Thursday, 8 a.m. to 10 p.m. Friday, 10 a.m. to 6 p.m. Saturday and 10 a.m. to 1 a.m. Sunday.
The ground-floor Starbucks cafe will keep the same schedule as Library West.
However, if not enough students are lining up for late-night snacks and drinks, Starbucks might revise its hours, Waldman said.
Student Body Treasurer T.J. Villamil said he has already heard positive feedback from students.
"They really want a place where they can go and study all night," he said.
