Hi, everybody!
As usual, non specialized journalists include a lot of "hype" and "hot 
air" in their articles to attract the attention of readers.
The cylinder Phonograph was invented by Edison in 1877, and the first 
prototype was built around December 4 of that year. He applied for a 
patent on December 24.
Abraham Lincoln was very much dead by then, much less would you find 
recordings "from the early days of slavery".
And we make fun of people who ask for motion picture archival footage 
of the American Civil War...
These journalists deserve some kind of award.
