AUC’s Rare Books and Special Collections Library (RBSCL)[8] was created in 1992, the combination of the Main Library’s Special Collections unit which maintained university archives and assorted rare books and maps, and the library of the university’s Center for Arabic Studies, focused on Islamic art and architecture. These libraries had been brought together in a restored 19th-century villa at the downtown Tahrir Square campus, but the RBSCL moved with most of the university to a new campus in the suburbs of Cairo after 2009. During the Egyptian Revolution of 2011, the Library's staff and preservation experts helped save some of the contents of the Library of the nearby Institut d'Égypte.[9]
