The U.S.A. Trilogy is the major work of American writer John Dos Passos, comprising the novels The 42nd Parallel (1930), 1919, also known as Nineteen Nineteen (1932), and The Big Money (1936). The three books were first published together as a one-volume edition in 1938, to which Dos Passos added the prologue labeled "U.S.A." The trilogy employs an experimental technique, incorporating four different narrative modes: fictional narratives telling the life stories of twelve fictional characters; collages of newspaper clippings and song lyrics labeled Newsreel; individually labeled short biographies of public figures of the time such as Woodrow Wilson and Henry Ford; and fragments of an autobiographical stream of consciousness labeled Camera Eye. The trilogy covers the historical development of American society during the first three decades of the twentieth century.
