The newest addition to the University of Chicago Libraries system, the Joe and Rika Mansueto Library opened to the public on May 16, 2011. Featuring a glass-domed reading room and a state-of-the-art underground storage and retrieval system for research materials, Mansueto promises to keep archived research materials within short walking distance of UChicago faculty and students. The Library was funded by a generous $25 million gift from Joe Mansueto and Rika Yoshida, both alumni of the University.
