Our librarian friend Rebecca Hunt (really, all of you should have a librarian friend) alerts us to the launch of the online Juilliard Manuscript Collection, lovely digital images of the trove donated to the school last year by their board chairman, Bruce Kovner. Lots of serious, scholarly stuff here—autographs, sketches, composer-corrected proofs—but, this blog being what it is, we’ll skip the serious and scholarly and head straight to these two drawings of Aaron Copland that Leonard Bernstein saw fit to add to the manuscript of his piano arrangement of El Salón México.
