The Alan Lomax Sound 17,000 Recordings free archive

A huge library of songs and interviews recorded by the legendary folklorist Alan Lomax from the 1940s to the 1990s have been transferred to digital and available online for free. The Association for Cultural Equity, a nonprofit organization founded by Lomax in the 1980s, has posted some 17,000 recordings.
“For the first time,” Cultural Equity Executive Director Don Fleming told NPR’s Joel Rose this week, “everything that we’ve digitized of Alan’s field recording trips are online, on our Web site. It’s every take, all the way through. False takes, interviews, music.”
