This series is divided into four sub-series and consists of different materials related to "Catch-22" at several stages. Sub-series 1 contains autograph and typed manuscripts, corrected galleys from the publisher Simon & Schuster, and written material that never appeared in the final publication. This sub-series also includes an annotated copy of "Catch-22" with extensive handwritten notes in the margins, intended to clarify and explain sections of the novel for a motion picture version. Sub-series 2 contains letters expressing the reception of Catch-22 from the general public, as well as correspondence with producers and writers, such as Tony Curtis and John Steinbeck. In addition, there is correspondence relating to foreign editions of "Catch-22" from several countries. Sub-series 3 contains charts used to outline characters and events in the novel chronologically; annotated photographs from a "United States Air Corps Squadron Book" that show people and events that inspired some characters in the novel; and maps of Corsica that were drawn from memory for Columbia Pictures. This sub-series also contains chronological descriptions and analysis of characters and events intended to assist in the preparation of the movie version. Sub-series 4 contains news clippings and reviews from different countries, as well as critical essays and interviews with Joseph Heller.
