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 Marie Webster Study Collection contains both professional and personal materials that document Webster's career as a quilt designer. A majority of the items in the collection date between 1911 and the 1920s, with a few earlier items like photographs and a scrapbook that documents her later life. Many of the quilt patterns and templates in the collection connect to finished pieces found in the museum's permanent collection.
