The Gardner Sage Library, dedicated in 1875, contains over one hundred fifty thousand books and over ten thousand bound periodicals, including three hundred periodicals on current subscription. More than one thousand additional publications are accessioned annually. This collection of theological works is ecumenically rich, and supplemented by unusually strong resources in the Classics, fine arts, social sciences, Dutch and Dutch Colonial Studies, and Reformed Church History. This collection is augmented by reciprocal borrowing rights with the Rutgers University library system (over 10.5 million holdings).
