The library has a collection of CD's and LP's that can be found on the second floor.
While some items follow the Library of Congress call number system, the majority of our audio materials are arranged simply by the format (LP or CD) and a number. When you find the resource in the catalog, take note of the format and number before going to look for the item.
Through the Great 78 Project the Internet Archive has begun to digitize 78rpm discs for preservation, research, and discovery with the help of George Blood, L.P.. 78s were mostly made from shellac, i.e., beetle resin, and were the brittle predecessors to the LP (microgroove) era.
Recordings in the Jukebox were issued on record labels now owned by Sony Music Entertainment, which has granted the Library of Congress a gratis license to stream acoustical recordings.
This collection is the largest repository of commercially produced vernacular recordings in existence. They have been digitized from the original and can be searched by keyword or browsed by artist or label.
