The Main Library has a mix of open spaces, good for group work, and quiet spaces. There are work tables on each floor, and whiteboards on the 1st and 4th floors. The first floor has some chairs that have a laptop shelf so that a person can find a good study nook, without having to be in a group, even in a group work area. The collaborative study space is on the 4th floor. If you come from the elevators, the space would be to left. Look for signs for rules about food and drink. There are some limitations. The Main Library is open until 2 a.m. on most semester weeknights. HOURS are shortened on weekends (that includes Fridays) and the Library is closed on home football game days!
The Miller Learning Center has 96 group study rooms. These are available on a first-come-first-served basis, and groups of two or more have precedence over a single person. There are also plenty of carrels, tables, and computer spaces. You'll find rolling whiteboards from the 2nd floor up. There are even three FitDesks -- laptop/study desks designed to be used like exercise bikes.
The 4th floor is the quiet floor where you'll want to whisper. There is also a super-quiet Reading Room on the 3rd. Normal conversation volume is fine everywhere else in the building.
There is a Jittery Joe's coffee shop on the 2nd floor, and it can get a little loud and social in that area. The MLC is also right across from the Tate food courts. You can have food and drink in the MLC. Just be sure to report any spills. The MLC is on 24-hours schedule most of the semester, but keep an eye out for HOURS changes around holidays and breaks!
The Science Library has just undergone a renovation adding some nice study spaces to its 3rd floor (image immediately below). The first floor area also has laptop chairs, computers, restaurant-like booths, tables and rolling whiteboards (second image). With a photo ID, you can check out an extension cord, white board markers, and erasers for group work. There is also a quiet "Think Tank" space with tables and carrels. HOURS are the same as the Main Library.
There's a Jittery Joe's coffee kiosk just outside the Science Library, in the Boyd building lobby.
