The papers include correspondence between Labatut and important twentieth-century architects, landscape architects, and designers, such as J. C. N. Forestier, R. Buckminster Fuller, Sigfried Giedion, Arthur C. Holden, Victor Laloux, Albert Leclerc, LeCorbusier, Auguste Perret, and Robert Venturi. Notable is his extensive correspondence with Jacques Maritain from 1956 to 1973.

The subject files contain all materials-that is, correspondence, documents, notes, sketches, plans and blueprints, photographs, and printed matter-related to Labatut's major and minor projects, which include the 1939-1940 New York World's Fair, the Monument to José Martí (Havana, Cuba), the Stuart Country Day School of the Sacred Heart (Princeton, New Jersey), and Labatut's entries for architectural competitions of the 1920s and the 1930s. In addition to project files, the subject files also contain the administrative papers and teaching materials accumulated by Labatut while he was the Director of Graduate Studies in Architecture at Princeton University (1928-1967); materials pertaining to various awards received by Labatut, including the Thomas Jefferson Medal and Professorship in Architecture awarded by the University of Virginia (1972-1973) and the ACSA/AIA Award for Excellence in Architectural Education (1976); and miscellaneous travel files kept by Labatut, which include photographs, sketches, and printed matter regarding his 1936 flight on the Hindenburg.

Included in these subject files is a large collection of Labatut's guache drawings for the New York World's Fair (1939-1940) fireworks, as well as plans and blueprints for the execution of the fireworks. In addition, there is a group of photographs (and negatives) and fifty glass lantern slides.

The papers also contain writings by Labatut, primarily in the forms of articles and speeches, photographs, artwork, audiotapes, stamps, plaques, Christmas cards designed Labatut, and printed matter.

In addition to Labatut's professional papers, the collection contains his family papers. Aside from correspondence exchanged between Labatut and his wife and brothers, the family papers include some papers and several albums of photographs that belonged to Labatut's sister-in-law, Mrs. Elliott F. Shepard (née Eleanor Terradell), who helped to operate a convalescence home founded by her husband for soldiers of World War I in Chantilly, France.

Also present is a 16mm lab copy of a film recorded by Jean Labatut as a passenger aboard the Hindenburg on a transatlantic trip from June 23-26, 1936. There are four cartons of reels and canisters containing uncatalogued film taken by Labatut--in questionable condition. These have been stored off-site for preservation purposes.
