The Mildred Fox Everett papers date from 1811 to 1972 and measure 4 linear inches. Included are one letter from the Fort Pierre, South Dakota, school board offering Fox a teaching job; a copy of a lease; a typed interview between Fox and her daughter and son-in-law, Alice and Vyron Truog; and a map of Stanley County, South Dakota, where Fox lived. The lease by which Fox rented out her land when she left South Dakota in 1908 is a photocopy of the original. The interview (undated) details Fox's life as a homesteader and teacher in Fort Pierre, South Dakota.

A Scrapbook contains genealogical information about the Fox family, including research notes and photographs from Fox family sites in Ireland. In addition are photographs covering the entirety of Everett’s life, including photographs of her childhood and extended family, as well as newspaper clippings about family members.
