The Library - A unique collection

As the most comprehensive Bach collection anywhere, the library features a matchless array of original Bach sources, manuscripts, rare books, and early editions. The remains of the old St. Thomas School Library constitute its oldest part. Next to the State Library in Berlin it contains the largest collection of original Bach sources in the world, among them forty-four sets of original performing parts from the composer’s second Leipzig cantata cycle of 1724-25, the so-called chorale cantatas.

The extensive holdings of music and literature on music from the 16th century up to the present are complemented by photocopies of Bach sources scattered throughout the world, sound recordings, graphic art in addition to coins, medals, sculptures, press cuttings, films, slides, and many other items.

The library systematically expands its collections by acquiring all relevant current publications and recordings as well as, whenever possible, rare materials on the antiquarian market. An electronic catalogue provides manifold access points to the various collections.

The reference library is open to the general public and serves scholars, students, musicians, and Bach lovers alike.
