Cosgrove’s collection consists of approximately 2,500 pages and falls into the years 1928-1931. The bulk of the collection consists of correspondence, the majority being letters from his then fiancée Mary I. Ross (class of 1931). Other correspondence include letters from family, classmates, and people related to the college. Included in this collection are correspondence from Florence Schornstein, Velma Brassell, Mrs. Cosgrove, Dr. E.J. Davis, Virginia Faris, and Dorothy C. Grow. The final series of this collection consists of college notebooks, class essays, exams, and personal effects such as pens, keys, a family bible, and a belt buckle. Through reading the correspondence in this collection, one can get a clear idea and feel for what student life was like at Gallaudet College during the late twenties. Social, residential, as well as academic responsibilities and activities are described throughout the correspondence.
