Today Boulton's large collections of traditional music materials are found at several institutions. The Columbia University Center for Ethnomusicology has the Laura Boulton Collection of Traditional Music, with approximately 30,000 field recordings and accompanying documentation, purchased for Columbia in 1964. Boulton served as curator of this collection from 1962 to 1972. Boulton's liturgical music collection is found today at the Harvard University Archive of World Music, part of the Eda Kuhn Loeb Music Library. The Music Library has digitized this collection and made it available on the World Wide Web.
