19th Century music recordings

  This is a very obscure thing that i do not know alot about and would welcome additional info on
     what i do know-
         In 1860, a recording of a woman singing the beginning of Claire de Lune was recorded,, initially onto a graph,there being no way of reproducing what was recorded. In England just a few years ago, it was reconstructed and there was the means to reproduce what existed.
               I am sure many of you will know about Thomas Edison's famous recording of Mary Had A Little Lamb, which i am not sure of the date of, possibly 1877?
                I also read that after that recording, nothing else was done until Enrico Caruso's vocal recordings at the beginning of the 20th Century.
                 Is there anything before Caruso that i am missing?
                    Is the Edison recording, and that of the woman from 1860 actually available to be purchased on Cd?
                  

I heard about the French recording. It was made by a needle etching a sound wave into soot on paper. Extremely primitive, but genius. The oldest recoring I personally have is of Allessandor Moreschi, the last castrato, from 1902. I love old recordings and am looking to expand my collection, but they're hard to come by.
