Dear all, I wonder if anyone could point me in the direction of a published source or two on the history of data compression - Shannon-fano, Lempel-Ziv-markov etc. - as I have been unable to find any mention of these algorithms as a historical subject in anything peer-reviewed or from a decent publisher. The only sources I can find that discuss the topic are a few websites or early draft working papers. I am writing an environmental political theory article which discusses technological change and good sources on this topic would be a great help. Any assistance you could provide would be very much appreciated.
