I noticed today that the Crerar library changed its hours for the rest of the summer. These weeks are crucial for graduate students writing dissertations. There were a lot of students in the first floor and all of us were wondering why you changed the hours at the end of the summer. There is no other space in the University with extended hours so I would really request that Crerar keep its normal summer hours.
Traditionally both Crerar and Regenstein have closed earlier in the evenings during interims/breaks. (Generally, 8pm for Regenstein and 10pm for Crerar.)
While we understand this inconveniences people who enjoy studying late into the night, having shortened hours during interim allows us to save some money. Further, this year we have a security guard doing walk-throughs of Crerar and Regenstein at closing, and this has required us to keep the closing times of both buildings within a few hours of each other.
Even with our reduced building hours, Crerar is still open over 90 hours each week. The building will also be open Labor Day, a University holiday, for 14 hours (8am-10pm).
