The Department of Rare Books and Special Collections sponsors two major exhibitions a year in the Main Gallery located on the first floor of the Firestone Library. The Cotsen Children's Library includes an interactive exhibition gallery for children. In addition, materials from the collections are displayed in various lobby cases, in online galleries, and in the exhibition gallery of the Seeley G. Mudd Manuscript Library at 65 Olden Street. All exhibitions are free and open to the general public. For information on current exhibitions, consult the links below or check News at Princeton.
