De Revolutionibus Orbium Coelestium by Copernicus is on the auction block at Christie’s for about $1 million.  Buy it before the crazies burn it and assert that the sun revolves around the earth.  Snide commentary aside, sales like this make me cringe because, to my renaissance-driven mind, this book belongs to everyone and not snug inside a hermetically-sealed case in some gazillionaire’s study.  Good thing then that the Lehigh University Digital Library scanned the book and Harvard makes it available online.  (Check out pages 16 and 18 on which some astrophysicist punk underlined sentences and made notes in the columns.)  Viva la internet!
