This exhibition was composed of the Goldberg Variations, lent by Elena Presser, and, the Anna Magdalena Bach Notebook, lent by the Sackner Archive. Critical essays were contributed by Elena Presser and Rosalyn Turek, the Bach scholar and musician. The director, Elsa Weiner Longhauser, describes the Sackner Archive as "a brilliant, comprehensive collection and Presser's work a rare tour de force." -- Source of annotation: Marvin or Ruth Sackner.
