The fifth floor was devoted to exhibition space, a general dining room, and a private dining area for faculty. The floor plan shows the exhibition area wrapping around the double stairway that led to the library below. Includes some original drawings.

The library occupied the entire fourth floor. Behind the librarian’s desk in the center of the floor is a triangular wall of shelves formed by staircases on either side leading to the exhibition gallery above.

The library was relocated to the List building during the 1950s expansion, and the fourth floor repurposed for classrooms and offices. Includes some original drawings.
