The Great 78 Project is the Internet Archive’s project to digitize hundreds of thousands of 78rpm vinyl records,
From about 1898 to the 1950s, an estimated 3 million sides (~3 minute recordings) have been made on 78rpm discs. While the commercially viable recordings will have been restored or remastered onto LP’s or CD, there is still research value in the artifacts and usage evidence in the often rare 78rpm discs and recordings. Already, over 20 collections have been selected by the Internet Archive for physical and digital preservation and access. Started by many volunteer collectors, these new collections have been selected, digitized and preserved by the Internet Archive, George Blood LP, and the Archive of Contemporary Music.
At the time of this writing, they’ve digitized more than 35,000 78rpm records.
