Sing Out! is a quarterly magazine dedicated to the preservation of traditional and contemporary folk music. It also is a membership organization that grants subscribers access to a resource center where tens of thousands of LPs and CDs and hundreds of books and other ephemera on folk music are kept. The magazine headquarters were moved from New York to the Lehigh Valley in 1982, and Sing Out! has occupied this location in south Bethlehem for more than 10 years.
