I’m happy to report that my publisher, Theodore Presser, has started putting perusal scores online. The files can’t be downloaded or saved, but you can peruse to your heart’s content. I have two pieces posted so far: Songs for Adam, my song cycle for baritone and orchestra, commissioned by the Chicago Symphony; and Four Sacred Songs, a set of arrangements of chant melodies with Latin texts for mezzo-soprano (or soprano), flute, clarinet, percussion (1 player), harp, violin and cello. Presser did a decent job of posting at least a few items from most of the composers in their big catalog - there are over 450 items here.
