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 IMA Archives Exhibition Records document the planning and execution of exhibitions created by and/or held at the Art Association of Indianapolis, the John Herron Art Institute, and the Indianapolis Museum of Art starting in 1883 and continuing through the present day. This collection is ongoing, as the Indianapolis Museum of Art continues to create new exhibition records each year. Individual exhibition files may include checklists, exhibition catalogs, installation photography, correspondence, press clippings, curatorial research files, shipping, receiving, and lending records, and other documentation. A file and listing have been created for every exhibition, regardless of whether any archival material survives. File listings with "[empty]" indicate that there is no archival material available for the exhibition. Many early exhibitions do not have any surviving archival documentation. This is an ongoing project to process these exhibition records, starting with the earliest records.

The J. Irwin Miller And Xenia S. Miller Travel Papers document the travel, both business and personal, that the Millers did from 1960 to 1990. The materials include trip itineraries, travel journals, correspondence, purchase receipts, travel brochures, travel guidebooks, ticket stubs, menus, and other ephemera and records of their travels.

The Kurt F. Pantzer Collecting Papers document the fine art and book collecting of the Indianapolis businessman and civic leader who was known for having the largest collection in America of artworks by British artist Joseph William Mallard (J.M.W.) Turner (1775-1851). The archival collection was given to the Curatorial Department of the Indianapolis Museum of Art with Pantzer's art collection in the 1970s and was transferred to the archives in October of 2014.

The Percival Gallagher Papers document the personal and professional life of prominent landscape architect and partner of the Olmsted Brothers firm. In addition to research materials collected over the course of his life, Gallagher saved memorabilia from all aspects of his life, from handwritten notes about landscapes and gardens to travel souvenirs.
In 2015, the IMA Archives digitized all of the photographs and select manuscript material from Gallagher's papers. The digitized collection has been made available online through the Indianapolis Museum of Art’s Digital Archives Portal.

The Wilbur D. Peat Research Papers contain materials related to Peat’s articles, books, lectures, and classes predominantly from the years 1935-1958. The collection includes notes and index cards on Indiana artists and collectors, article clippings, bibliographies, exhibition catalogs, photographs of artworks, and correspondence with art collectors, curators and artists’ families.  The materials contain extensive notes relating to a number of Peat’s books including Pioneer Painters of Indiana, Indiana Houses of the Nineteenth Century, Chinese Ceramics of the Sung Dynasty, and Portraits and Painters of the Governors of Indiana, 1800-1943. A portion of this collection, relating to Pioneer Painters of Indiana, has been digitized in partnership with IUPUI University Library made possible by a grant from the U.S. Institute of Museum and Library Services, administered by the Indiana State Library.
