The digital collection American Choral Music: 1870 – 1923 is the product of a 2007 agreement between the Library of Congress (LOC) and the American Choral Directors Association (ACDA) to digitize and disseminate American choral music in the public domain. The collection seeks to represent an accurate and diverse sampling of American choral writing in the late 19th and early 20th centuries.
