Locating Sound Recordings
The Recorded Sound Section of the Library of Congress maintains
a collection of nearly 2,500,000 recordings, with receipts averaging
from 75,000 to 100,000 items in recent years. Historically, a large
portion of the collection remained uncataloged, but could be accessed
through inventories and the careful ordering of commercial recordings
by label name and issue number on the shelves. A major effort to
reduce the arrearage starting in the 1990's has led to a great
increase in the number of processed sound recordings in the Library's
catalog and a database, now available on the Web, known as SONIC
(Sound ONline Inventory and Catalog). What follows is an estimate
of the percentage of certain categories of material to be found
in SONIC,
the percentage available in the Library's main catalog (the Integrated
Library System or ILS), and the pecentage available by contacting
the Section's reference staff. Please note that field recordings
made by the Library are excluded from this matrix and researchers
interested in this material should contact the Folklife
Reading Room.
