Joe and Rika Mansueto Library at the University of Chicago

The newest library at the University of Chicago houses 3.5 million volumes under a bubble-like dome in Hyde Park. It was designed by prolific architect Helmut Jahn (who, among many impressive works, also designed the neon light display in O’Hare’s United Airlines terminal). Under the library’s dome is a 180-seat reading room, which is open to the public Monday through Thursday from 8am to 11:45pm, Fridays and Saturdays from 8am to 10:45pm, and Sundays from 10am to 11:45pm.
