This series contains the records of the Princeton University Library's Department of Rare Books and Special Collections. First organized in 1948-49, the Department has oversight of the Library's holdings of rare books, manuscripts, graphic arts, and numismatics, as well as several other special collections such as the University Archives, the Public Policy papers, and the Cotsen Children's Library. The origins of the Department of Rare Books and Special Collections extend nearly to the beginning of the Library, and much of this material predates the official formation of RBSC as a unit. Other records concerning the early Department of Rare Books and Special Collections can be found in Subseries 1D: Julian Parks Boyd. Please see subseries descriptions for further information regarding the individual subseries.
