In its 2004 edition of The Best 351 Colleges, the Princeton Review ranked Fordham's William D. Walsh Family Library fifth in the country, ahead of Yale, Harvard, and Columbia.[2] After the completion of the Walsh Family Library, the Duane Library was officially closed to students and faculty and sat empty until its 2004 renovation into a visitors' center and headquarters of the theology department.[3] The library occupies over 240,000 square feet (22,000 m2) on five floors, and contains more than 1 million volumes and 380,000 U.S. government documents.[4] All Rose Hill Library services, including the Science Library, Audio Visuals, Electronic Services, Government Documents, Archives, Special Collections, Microforms, and Fordham Dissertations are housed here.[4][1] The museum also showcases a collection of 732 ancient coins given by Thomas Maroney,[6] and Byzantine mosaics anonymously donated in 2013.
