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.

The Herron-Museum Alliance Records, 1964-1980, contains records regarding the Herron-Museum Alliance, post its creation in 1958. The collection is comprised of records produced and collected by staff. It documents the actions, initiatives, and operations of organization. The files that were originally foldered together but rehoused into new folders to assist in their preservation. Researchers will find information regarding publicity efforts and museum building plans of interest. More information regarding the Herron-Museum Alliance can be found within the IUPUI (Indiana-University-Purdue-University-Indianapolis) archives and specials collections.

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.

This collection is comprised of posters created by and for the Indianapolis Museum of Art and its predecessor organization, the John Herron Art Institute. Most of the posters were created to be ephemeral, to advertise museum events and exhibitions. Posters for events date from 1970 to 2013 and are housed in one flat file folder. Posters for exhibitions date from 1967 to 2008 and are housed in six flat file folders. Within each folder inventory, event and exhibition posters are listed in chronological order, but are physically arranged by size, from small to large.
One flat file folder houses posters that feature accessioned items from the IMA collections. Those posters are listed and physically arranged by size, from small to large.
