The Mary Santoli Pardo Collection documents her research and predominantly consists of correspondence, newspaper clippings, photographs, interviews (three related audio cassettes), and various newsletters and flyers. It has been divided into two series: Correspondence (1967-1997) and Research Files (1940-1997).
Series I, Correspondence, contains correspondence and is arranged alphabetically by the creator.
Series II, Research Files, contains articles, newspaper clippings, programs, interviews, flyers, and related items. This series also contains non-manuscript material, including audio-taped interviews conducted by Pardo, and photographs. The series is arranged alphabetically.
