E=mc2 Bibliography & web

Here it is the " Bibliography & web ". I have a huge personal & simbolic debt with the words that other individuals have found to pass their knowledge, to try to express something about their experiences. As others m i ght be interested in finding the ir precious knowledge, I include a bibliography to this paper. Where possible, in the bibliography a direct link is given from the titles to their downloadable version; no fees or registrations are required.
