Just before Christmas, the Morgan Library unveiled digitized versions of some of the most important music manuscripts in its collection. Mozart's "Haffner" Symphony, Mahler's Fifth Symphony, and Schubert's Winterreise are among the dozens of treasures on offer. (The image above is of the first page of the Adagietto of Mahler's Fifth. Note that he writes "Molto Adagio.") The library says that in the near future more than nine hundred manuscripts will be made available. This is obviously a major resource for musicians, scholars, and music-lovers.
