The Great 78 Project over at the Internet Archive has been professionally digitizing old 78 RPM records for a while now. These records were all made between 1898 and sometime in the 1950s. Over 20 collections have been selected for digital access and physical preservation with the help of George Blood, L.P. and the Archive of Contemporary Music. So far about 26,000 of the 78s have been added to the Internet Archive. Each disc has about 3 minutes of audio per side. Most of the discs are made from shellac and really quite brittle, perhaps even more brittle than today's digital formats.

Some 78 RPM records were made of vinyl, but shellac was much more common.
