The Aileen Ross fonds consists mainly of correspondence (1935-1990), research files, a brief autobiography (1940-1980), biographical material (1920-1990), and specific talks (1942-1973). Included are personal diaries (1918-1962), appointment books (1946-1992), and Matthew Ibbotson's correspondence to Ross (1921-1927). Books, original and printed articles, newspaper clippings, and reviews of books and articles are also part of the collection. Non textual records consist of several photographs.
