The United States Library of Congress has tons of interesting materials online, although navigating through the array of resources can be tricky. But sometimes, the LOC provides neat tools to use, like this simple interface called Push To Play.
When clicking the command, it randomizes its vast digitized collection of 78rpm records and begins to play some old-time music from its archives. Give it a spin, and then share out what you listened to (if you click on the Full Details At Archives, the site will bring you to the actual file).
