Correspondence, manuscripts, diaries, notebooks, and publications. The many manuscripts reflect Barzun's interest in poetry, literature and political affairs. The collection also contains materials for the journal, Art et Action which Barzun helped to found; lecture notes, 1933-1952; and a few items pertaining to Filippo Tommaso Marinetti and the Futurists. There are some Barzun family papers, as well. The correspondents are primarily French and American authors including André Breton, Katherine Dreier, Marcel Duchamp, Georges Duhamel, Albert Gleizes, Ivan Goll, Harriet Monroe, Ezra Pound, Pierre Reverdy, Edgar Varèse, Gabriel d'Annunzio, and Felippo Tommaso Marinetti.
