The Arthur Deshaies Collection was originally housed in a binder subdivided into three categories: "Regional," "National," and "International." Due to the inconsistent and disorganized arrangement of the material within these categories, the decision was made to rehouse the material in folders grouped by type of material: correspondence, exhibition ephemera, clippings, and memorabilia. The correspondence is between Deshaies and multiple galleries and museums that wanted to exhibit or purchase his work, and has been organized in chronological order by date. Notable correspondence includes the Atlanta Art Association, the Museum of Modern Art in New York, and Carleton College Art Gallery. Individual pieces of memorabilia have also been arranged chronologically by date.

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 J. Ottis Adams Papers Addition includes three scrapbooks containing clippings, ephemera, correspondence, and photographs of the artist’s home and studio. The first and second scrapbooks document the artist’s professional life between the periods of 1891-1927 and 1895-1904. The final scrapbook was assembled by the artist’s family and contains additional material and notes related to the artist’s life, dated between 1901 and 1967. A letter from the St. Louis World’s Fair Department of Art (1904) is also included.

The first series, Personal and Professional Materials, includes business cards, clippings, a postcard from the artist Clifton Wheeler, small black and white reproductions of the J. Ottis Adams painting The Gleaners, 1886, and an anonymous painting of Mary Queen of Scots, as well as the Adams family's inventories of the collection. The second series, Exhibition Materials, consists of exhibition catalogues, announcements, and art association bulletins. The last series, Journals, includes journals with articles about J. Ottis Adams, Winifred Adams, and other artists of the Hoosier Group.

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 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.
