If you're looking for quiet study space: The upper floors of both the Main Library and the Science Library are good spots for quiet study, particularly the 3rd floor Reading Room in Main and the 4th floor silent Think Tank in Science. The top floor of the Miller Learning Center is set aside for quiet study.
If you're looking for group study space: Half of the Main Library's 4th floor is dedicated to group study, with whiteboard on most of the walls and moveable tables and chairs. The Miller Learning Center has 90 group study rooms that are available first-come, first-served.
