How to use this collection: The cards duplicated in this collection came from Mari Sandoz' personal research files. The two notebooks which contain this collection constitue four library drawers full of research cards concerning the Oglala Sioux. As she read books and articles or reviewed research and interview notes, Ms. Sandoz would evidently keep a stack of note cards at hand on which she could record information and the numerous individuals she planned to include in her books and aeticles. Apparently she also took notes on dindivuduals who might or might not actually appear in a book, individuals whose life and times in some way touched upon the lives and times of the subect matter of her books. This is an immense collection of note cards kept by Mari Sandoz as she read, interviewed and researched Oglala Sioux history surrounding the period when Crazy Horse was living. There are four library drawers full of these cards at the Mari Sandoz Collection, and all of them have been copied and are available here. There is a large section on Crazy Horse, his family and band, almost a drawer full of cards on full bloods, a drawer on mixed bloods, non-Indians, and a section of cards on agents and agencies.
