A large assortment of her memorabilia and recordings constitutes a Special Collection in the Lovejoy Library at SIUE. In 1957 she published a book of memoirs, Forbidden Childhood, which deals with life as a child prodigy, and a book on piano technique, Music at Your Fingertips: Aspects of Pianoforte Technique.
