The Lilly House Records, 1967-2005, contains records regarding the Lilly House, primarily since its donation to the Indianapolis Museum of Art in 1967. A large portion of the collection consists of the file folders of paper documents. While there is a Photos and Media series, photos are also located in other series where they are relevant. The collection is comprised of records produced and collected by staff. It documents the history of the Lilly House. Many of the files were originally in binders and were kept in their original order. Researchers will find information regarding the families who lived there, the architects, building/restoration documents of value. More information regarding the Lilly House, the families that have lived there, and the architects who constructed it, can be found in the Bradley Brooks Collection (HIS 002).
