Changes to Library Building Hours (October 2025)

Effective October 26, UCSB Library’s building hours will change as follows for the 2025-2026 Academic Year (Fall, Winter, and Spring quarters):

• The Library will open to the public at 7:00 AM Monday-Friday, excluding university holidays and breaks.
• The Library will remain open to UCSB students, faculty, and staff from 1:00 AM to 3:00 AM on Sunday-Thursday nights for Study Commons in the Learning Commons on the 1st and 2nd Floors, Mountain Side. Study Commons is made possible in part through funding support from UCSB Associated Students (AS) and a partnership between the Library and AS, the Office of the Vice Chancellor for Student Affairs, and the UCSB Police Department.
  
  • Exception: During Dead Week and Finals Week, Late Night Study hours will be 6:00 PM to 7:00 AM, ensuring exclusive 24-hour access for UCSB students, faculty, and staff during the busiest times of the academic year.
