Scope and arrangement
The collection consists exclusively of scores, which date from 1928 to 1983. The scores are arranged alphabetically by composter, title, or dance company name. Most of the scores are not annotated, and contain little indication about how they are connected to Leon Danielian or Georgia Hiden. Some of the scores have either Danielian or Hiden's names handwritten on the front cover. One score, Tchaikovsky's Swan Lake, includes both dancers' names. The 1939 Robert Schumann score for Carnaval also includes a 1939 inscription to Danielian, and a flyer for a Ballet Russe de Monte Carlo performance at the Civic Opera House in Chicago.
