The Sound Recordings catalog comprises over 17,400 digital audio (and video) files, beginning with Lomax’s first recordings onto (newly invented) tape in 1946 and tracing his career into the 1990s. These materials stem from Lomax's independent sound archive (his earlier recordings for the Library of Congress are the purview of the American Folklife Center).
The James Koetting Ghana Field Recordings collection presents a vibrant mix of traditional and popular music recorded at a broad range of locations and events in Ghana during the 1970s by ethnomusicologist James Koetting. Students and researchers can hear online the complete archive of Koetting's field tapes — 142 audio reel tapes — of musical performances from arts festivals, traditional ceremonies and events, stage concerts, church services, and less formal gatherings and sessions throughout Ghana.
The National Jukebox is a project to digitize a part of the Library of Congress's holdings in early sound recordings. From their website: "the Jukebox includes more than 10,000 recordings made by the Victor Talking Machine Company between 1901 and 1925. Jukebox content will be increased regularly, with additional Victor recordings and acoustically recorded titles made by other Sony-owned U.S. labels, including Columbia, OKeh, and others."
"The collection is comprised of over 2,400 78-rpm recordings commercially produced for immigrant, ethnic, indigenous, and regional audiences by American record companies in the first half of the 20th century."
"Presents primarily photographs of musicians and music-related subjects held by Mills Music Library, dating from the late nineteenth century to the present. In addition to photographs, there are postcards, lithographic prints, advertising and promotional materials, posters, and other types of ephemera."
