I've been searching for days upon days to try to find some internet sites that will help me determine the distinct stylistic qualities of Mr. Bradbury's writing. I would greatly appreciate it if I could get some help finding these sites from my fellow Bradbury fans

Rather than spend days searching for web sites, why not spend days reading his work and determining for yourself what the distinct stylistic qualities of his work are?

The other possibility is to go to your community or a college/university library, and see what they have about Bradbury. They sometimes have books that collect essays on Bradbury's style, themes, etc.

Bradbury loves libraries. My guess is that one reason he doesn't think much of the internet is that it may keep people from going into the library like "they should".

The internet is one source of research. But don't forget the library.
