Also don't forget Bicentennial Man. I think there's be a modest halo effect, though I wouldn't have the info to quantify. Also... Asimov and Heinlein are rather huge names in science fiction overall. Dick, though.. I think if not for the movies would likely have the same range of works available as the rest. Still, you're right.. he has a halo effect that's quite out of scale with what other authors get.

Cordwainer Smith's book on the shelf was Norstrilia, right? It'd have to be that or Rediscovery of Man. The former I just introduced Drake to, and he seems to be most appreciative.
