Where can I find public sources of documents or information on the development of portable personal audio player technology?

I suggest you take a peek in one of the most detailed history of personal audio player technology by Steven Schoenherr, which was last revised on July 6, 2005. The site traces the origins of audio player technology which began during the year 1877, wherein "Edison made the first recording of a human voice ("Mary had a little lamb") on the first tinfoil cylinder phonograph Dec. 6, and filed for an American patent December 24. " The last historical note ends in year 2005, with the invention of the iPod Shuffle, "introduced on Jan. 11 the solid-state music player.

You can perform a google patent search at google.com/patents If the information you find there isn't sufficient, they have a link to the actual patent at the USPTO. Here's an example of one digital audio player: google.com/patents/about? Id=06YVAAAAEBAJ&dq=digital+audio If that's not quite what you're looking for and you're looking for an overview of how the technology was developed, try here: inventors.about.com/od/mstartinventions/....

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
