Scope and arrangement
The papers consist primarily of manuscripts and typescripts of poems written by Mitchell from 1884 to 1915. The material is in rough chronological order. A group of poems written earlier and put in typed form in 1935 have been removed from binders. A portion of this typed material comprises copies of poems arranged alphabetically by first word.
Also in the collection are many manuscript notes "reflecting Mitchell's ideas for his writings.
The collection also contains a very small amount of personal correspondence covering the period from 1888 to 1933. Among the correspondents are: his long-time friend Owen Wister, Herman Keyserling, Paul J. Patrick, Talcott Williams, and one incoming letter from Theodore Roosevelt dated 1916.
