The Dorothy Reifel Collection on J. Ottis Adams contains primary source documents and research files about the life and times of Indiana artist J. Ottis Adams, collected by Dorothy Reifel.

The Membership Records, 1903-1988 contains records related to membership to the Art Association, and all of its various iterations. Note there are gaps in records between 1911 and 1940, 1959 and 1967, and 1969 and 1981. Records within this collection are primarily member lists, membership cards, and correspondence.

The Boards and Committees Records, 1987-2009 contains records pertaining to the various boards, committees, and organizations that have served the Indianapolis Museum of Art at Newfields. The earlier records, prior to the name change in 1969, refer to the John Herron Art Institute. However, a large portion of the records in this collection were created after 1975. A majority of the records within this collection are agendas, minutes, and notes from various meetings. Other records include correspondence, reports, rosters, and plans. Most of the meeting records are arranged in chronological order. Early records created by the Art Association, beginning in 1897, may be of particular interest.

The Bret Waller Papers, 1989-2000, document Waller's tenure as director of the Indianapolis Museum of Art during the 1990s. The collection is organized by subject; materials related to collections and exhibitions, and building operations (including strategic planning) make up the bulk of the collection. Also of note are the materials related to the Lila Wallace Reader's Digest Fund initiative that the museum received funding from to increase the diversity of its audience.
