Henry Teller has been the subject of a variety of nineteenth- and twentieth- century articles and a book. Elmer Ellis wrote a detailed biography, Henry Moore Teller: Defender of the West (1941), but since that date no others have appeared.

Thomas Dawson material is found at the Colorado Historical Society. Colorado College's Special Collections contain some Teller items. Other Teller letters and primary documents are scattered throughout a variety of collections, and some are in private hands, as indicated in the notes.
