All of the letters to and from Erasmus Correll are part of the Erasmus M. Correll Papers, MS 572, Nebraska State Historical Society.
The Western Woman's Journal is also part of that collection. Other newspapers are accessible at the Nebraska State Historical Society. The Harriette Robinson Shattuck Scrapbooks, which are on microfilm as part of the Arthur and Elizabeth Schlesinger Library on the History of Women, were valuable as her records provide a clear boots-on-the-ground account of traveling in northeast Nebraska.
