The Florence Polk Holding Papers consist of correspondence, a course notebook, writings, a commencement program, and biographical information. The papers primarily reflect her social and academic life as a student at Mount Holyoke College, 1898-1902. The bulk of her correspondence was written while she was a student at Cushing Academy in Ashburnham, Massachusetts from 1896-1898 and at Mount Holyoke College, 1898-1902. Letters written to family from Cushing Academy relate to her plans to attend Mount Holyoke, academics, and adjusting to being away from home. Several of the letters were written to her father while he traveled through the United States West. The letters from her years as a student at Mount Holyoke College discuss her studies, trips to Northampton, Holyoke, and Springfield, Massachusetts with friends, her plans for holiday breaks, and items she would like sent from home. Holding mentions traditions such as the Senior-Freshman Reception and notes attention paid to her by College presidents Elizabeth Storrs Mead and Mary Emma Woolley. Holding's papers include one letter to her brother and another to a friend, both of which focus much more heavily on her social life. These letters reflect Holding's interest in Yale men and other social activities. Contained in the papers is a zoology notebook used for Zoology 1 and 2 (1900-1901), which shows her meticulous work in sketching diagrams of various invertebrates. Another significant portion of the collection consists of letters written during her adult life. Five letters are from Frances Perkins who was Holding's classmate and Secretary of Labor for Franklin D. Roosevelt. These letters reflect a strong friendship between the classmates and show a more personal side of Perkins. They primarily discuss plans to see each other and class reunions.There is also a sympathy letter from Perkins to Holding, offering condolences for the death of Archibald M. Holding. In one letter dated March 9, 1953, Perkins discusses the death of her husband Paul Caldwell Wilson in religious terms, and thanks Holding for her condolences. This letter also comments on the need for political, economic, and spiritual diversity in the United States. Perkins also praises Holding's writing, as do William Lyon Phelps and Mary Emma Woolley in other letters. This writing, which is included in the collection, consists of an article Holding wrote for the May 1943 "Mount Holyoke Alumnae Quarterly" entitled "Another Famous Mount Holyoke Husband," which was about Owen Roberts, husband of Elizabeth Rogers Roberts, Class of 1902, and her book "Oiseaux de Passage" (1932) which describes two summers of travel in the Fontainebleau region of France.
