I heard on KCLU this morning that the library at UC Santa Barbara has archived a lot of old Edison cyliners and put them online, so now it's your one-stop shop for a bunch of now-dead people playing the hell out of old marching band tunes, giving historic speeches, singing turn-of-the-century opera, and Adelina, the Yale Boola Girl ("Rah! Rah! Rah!").
