There is copious correspondence with important art collectors and figures in the history of Smith College, as well as other educational institutions such as Columbia University. Researchers interested in Oberlin College, family history and the social history of the Midwestern U.S. will find the manuscripts and typescripts of his unpublished book Midwestern of interest. Genealogists will find some mention and dating of family names coming out of New England such as Franklin and Churchill. Art historians will be interested to note Churchill's writings and lectures on the teaching of art, and his role in developing an American taste for French Romantic painters.

This collection is organized into four series:

• I. Biographical Materials
• II. General and Professional Correspondence
• III. Museum and Art Collecting
• IV. Publications and Teaching Materials

There is some overlap in categories, but in keeping with the "respect des fonds," it was thought best to retain where possible the arrangement of certain folders which Churchill himself devised.
