Recorded Sound Research at the Library of Congress

Recorded Sound Collections

The Library of Congress holds the nation's largest public collection of sound recordings (music and spoken word) and radio broadcasts, some 3 million recordings in all. Recordings represent over 110 years of sound recording history in nearly every sound recording format and cover a wide range of subjects and genres in considerable depth and breadth.

The sound recording archive began in the 1920s when phonorecord companies gave the Library samples of their records. About the same time, the Library's Archive of American Folksong started assembling a rich collection of original field recordings of American music and folklore.

A grant from the Carnegie Corporation in 1940 started the Library's Recording Laboratory. Later, technological advances in the post-war years--the LP in 1948, and later the tape recorder-- boosted the sound recordings collections by generating commercial and personal materials. The Library's audio collections are now the largest in the United States and among the most comprehensive in the world.

NBC Radio's broadcast discs, 1935 to 1970, brought to the Library radio coverage of the Depression, World War II, post-war recovery, and a rich mine of radio drama and comedy. Armed Forces Radio, the WOR-AM collection, United Nations recordings, and the Library's own concerts and literary recordings further broaden the collections. Now, the recorded sound archive reflects the entire history of sound technology, from the first wax cylinders through LPs, tape, and CDs, to digital files.

The collection overviews presented below are representative of the breadth of our holdings but are by no means an exhaustive list of all of the recordings we have. Please get in touch to learn more about our collections and all they have to offer!

As with classical music, the Library has collected popular music since the early days of the recording industry. Gifts from Victor, Columbia, and Decca in the first half of the 20th century established the collection. After new laws in the early 1970s allowing the copyright registration of sound recordings, the Library has received published popular music recordings through copyright deposits. Prior to the 1970s, the Library relied on gifts and agreements with major record labels to send new releases to the Library for cataloging. Advances in recording technology in the 1940s and 50s greatly increased the number of records the Library received from record companies, and the acquisition of several significant special collections helped fill in gaps in the Library's pre-1972 commercial holdings.

Popular music has arrived at the Library on many formats throughout the years: 78 rpm disc, 45 rpm disc, long-playing disc (LP), tape, and CD. Popular music genres include blues, country, traditional and folk, musical theater, big band/swing, pop, rock, and hip hop/rap.

Many commercial recordings of popular music can be found in the Online Catalog.
