María today passed on to me the URL to Music Memory (http://www.musicmemory.org), a US-based project to preserve historical and traditional American and international musical sound recordings for posterity:
Music Memory’s mission is to preserve audio recordings for present and future generations. We are continuing the work started by the collectors and researchers in the 1950s and ’60s. We share their passion to keep the history of our musical heritage from being forgotten and are committed to preventing that from happening. As of May 2013, we have digitized more than 15,000 records on location at the homes of several prominent record collectors. Our goal is to build a database complete with audio, discographical information, artist and composer biographies, song lyrics and notation. Our hope for this database is that it will serve as a musical Rosetta Stone for future generations by showing the links and cross-influences of the many musical styles captured on phonograph records in the first half of the 20th century.
Somewhat broader than our own project, but with comparable aims. See also the article ‘Unforgotten Songs‘ in The Economist reporting the project.
