The Discography of American Historical Recordings (DAHR) is a database of master recordings made by American record companies during the 78rpm era. The DAHR provides these original recordings, free of charge, via audio streaming, along with access to the production catalogs of those same companies. DAHR is part of the American Discography Project (ADP), and is funded and operated in partnership by the University of California, Santa Barbara, the National Endowment for the Humanities, and the Packard Humanities Institute.
The database catalog is essentially based on physically accessible archive material, stored at the companies that still exist and others that succeeded the production companies that were active at the time. Catalog compilations created by specialist authors are also used, supplemented by newly acquired research knowledge.
