Yankee singing schools and the golden age of choral music in New England, 1760-1800

I have seen this book at the University of Pittsburgh music library and I intend to buy it. It's Buechner's PhD dissertation, edited with loving care and many illustrations. It is scholarly but very lively and readable, including many quotations from letters and diaries of the era. If you are interested in the music of William Billings and his contemporaries, this is a must-have.
