The original manuscripts to his over fifty transcriptions for cello ensemble and other combinations, including several unpublished works, are an important part of the Varga Collection. Among these manuscripts are his solo cello transcriptions of the Bach D minor and E major violin partitas, and cello/piano arrangements of the Schubert F minor Fantasy op. 103, and the Kodaly Dances of Galanta (originally for orchestra). The collection also includes works written for the Varga Cello Quartet by Gunther Schuller, Robert Starer, and Meyer Kupferman, and other original cello quartets by Alain Kouznetzoff, Richard Heller and Arvo Paart.
