The biographical material in this series includes five chapters of Marsh's projected autobiography, begun the year before his death and known as his "Narrative Volume." One chapter of this unfinished work, condensed in the Schuchert-Le Vene biography, provides a vivid account of a buffalo hunt when Marsh was caught on muleback in a stampeding herd. Also included are letters between Ernest Howe and George Bird Grinnell and between Howe and Schuchert concerning biographies of Marsh, a 1940 exchange between George F. Eaton and J. Donald Adams of the New York Times, and an album of obituary clippings on Marsh.
