The Margaret E. Jackson Papers, donated by her niece, Mrs. James O. Burri, consist of letters, miscellaneous articles, manuscripts, photographic materials, and a number of publications by the Hispanic Society of America for which Margaret E. Jackson photographed the illustrations. The collection, which consists of approximately 300 items, dates from 1925 1982. The bulk of the collection consists of letters to Margaret E. Jackson, her personal photographs, and the publications of the Hispanic Society of America. Many of the letters reflect her concern for aiding the deaf population. Correspondents include: Marguerite Colas, Maurice Colas, Irving Fusfeld, Jean Hanau, Thomas Hinchey, Suzanne Lavaud, Edward C. Merrill, Jr. She also corresponded with deaf artists Robert Dessales-Quentin, Émile Dudoret, Vilém B. Hauner, Kelly Stevens, and Valentin de Zubiaurre. A number of the slides and a few of the photographs relate to her photographic work with the Hispanic Society of America. Most of the photographs are personal photographs of herself, family, or friends. Many of the publications are hardcover with several signed by their respective authors.
