Correspondence and manuscripts of Barnard, spanning his adult life from 1831 to 1889. The majority of the correspondence covers his positions as President and Chancellor of the University of Mississippi and President of Columbia College. Addressees prominent among Barnard's outgoing letters include Edward Claudius Herrick, Eugene and Julius Hilgard, and Simon Newcomb. The letters to the Hilgards, many of which are photostatic copies, deal with the University of Mississippi. There are several letters each to Barnard from Alexander Dallas Bach, William Cullen Bryant, Howard Crosby, James D. Dana, Morgan Dix, Hugh McCulloch, John Greenleaf Whittier, and Theodore Dwight Woolsey. This collection also contains five volumes of Barnard's manuscript sermons, two volumes of miscellaneous addresses and speeches, and a manuscript volume of his autobiographical reminiscences with letters bound in, some originals, some typescript copies. There is also a photograph album of the University of Mississippi Class of 1861, including several campus views.
