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 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.
