Ok. This is cool. Absolutely cool. Artist Ward Shelley has sketched out a mind map to the history and evolution of the science fiction genre. It’s amazing. Click through to the big image and check out the areas around cyberpunk (upper right-ish) and the “Star Wars effect” (follow the arrow from Star Wars). He used spatial relations too. So the closer a name or title is to a sub-genre the more “canon” it/they will be. Pretty cool way to pick up new titles and authors to track down.
Someone should do this for all of the genres. A biblio-mystery mind map would be cool. I’ll buy the colored pencils! Who’s with me?
