H.G. Wells gets his own time machine. Jules Verne floats above Science Adventure and Fantasy Adventure in — what else? — a balloon. And everything from Dante and Voltaire to William S. Burroughs and steampunk has a place on this ginormous, shockingly comprehensive, and lovingly constructed History of Science Fiction map.

But be warned: if you’re a sci-fi fan, you may just fall down this fascinating rabbit hole and lose a whole hour. [via MetaFilter]
