Q. What hours is the library open?

All library users should follow current Butler University and library protocols. Hours are subject to change due to holidays, campus events, other unique circumstances, etc., so please check the Library Web page (butler.edu/library) hours tab which links here (to https://www.butler.edu/library/about/hours/) for the most up-to-date information on our hours! Any changes to hours will be posted to Butler Today. Also, follow us on Facebook, Instagram, or Twitter to receive quick updates on events or circumstances that may cause the library to be closed unexpectedly.

When the library is open late nights during fall and spring semester, doors to Irwin Library lock most nights at 7 PM, and to gain access to the building after this time, an active Butler ID is required. The Science Library in Holcomb 200 is staffed Monday-Thursday 9 am- 4 pm.  Outside of those hours, Science Library access is 24/7 via active Butler swipe-card only.
