Anthony, Ted. "Edison's Voice on Cylinder." Las Vegas Review-Journal & Sun (Las Vegas, NV) Feb. 4 1996: 7C. SIRS Researcher. Web. 09 March 2010.
This source talks about some of the earliest recordings found of Edison himself. It also goes into detail about some of the earliest uses for the phonograph. The main article though is about one of the earliest recording found of Edison. This cylinder was recorded in 1888, and is a recording of Thomas Edison addressing Mr. Blaine, a congressman at the time. This article also explains what kind of work went into restoring and re recording the old message, and why it had gone unknown for so long.
