The Gustavus A. Pfeiffer Physics Library is open as a study space in Compton 340. It is no longer considered a campus library. While there are reference books, the majority of the collection is now housed in Olin Library, Level B.
There are uncatalogued print copies of physics and math dissertations and theses along the wall to the let of the staircase.
The doors are open from 7:15am-4:00pm, Monday-Friday.
