The Library of Congress has a project called National Jukebox to digitize 78 rpm records from before 1925. Currently they have 10,000 recordings on-line and are adding to that collection every week. The collection covers all kinds of recordings from that era including popular music, folk music, foreign language, classical and spoke word. You can search for a composer, artist, song, etc. Then you can create a playlist to play multiple songs in a row.
The technicians at LOC have used modern technology to create the best possible reproductions but there are still pops and cracks. This was a time before electronic recordings. Artists played into a large horn that was connected to a stylus on a wax disk.
