BBC - Juilliard given rare manuscripts: Original manuscripts by Bach, Mozart and Brahms form part of a 139-item collection of sheet music donated to the Juilliard School in New York. The artefacts - donated by collector Bruce Kovner, chairman of the music acedemy's board - will be housed in a reading room from September 2009.

The Times - Tycoon orchestrates huge musical gift: A collector who has spent the past decade anonymously acquiring some of the world’s most revered musical manuscripts stepped out of the shadows yesterday to make an astonishing gift to the Juilliard School in New York, the leading US conservatoire. Bruce Kovner, one of the world’s highest-earning investment managers, gave more than 140 manuscripts - together worth tens of millions of pounds - to the school.

The New York Times has more information, plus a multimedia presentation with details about an autograph manuscript of Ludwig van Beethoven's "Grosse Fuge."

Alex Ross, music critic of The New Yorker, presents some images and a list of highlights from the collection, which includes:

The long-lost transposed continuo part of Bach's Cantata BWV 176, with markings by the composer.

Alex's post also includes a PDF of the complete listing of items.
