Tens of thousands of academic papers from Philosophical Transactions of the Royal Society are being shared via BitTorrent thanks to the work of someone going by the name Greg Maxwell. All of the papers are out of copyright — they date from the time of Newton up through 1923. Nevertheless, they have until now been locked up behind a paywall. Hopefully others in possession of such troves will follow suit. Scientific publishing is long overdue for this kind of shakeup.
