I am working on a literary research paper. My assignment is to discuss and interpret at least four recurring themes, symbols, and/or ideas from Bradbury's fiction. I have chosen to discuss the recurring settings from his stories such as Green Town, October Country, Mars, and outer space. I can not find much criticism on the internet. Can anyone help me find any information? Any kind of help would be appreciated.

Go to this site and scroll down. One of the FAQs is on critical books on Bradbury. http://home.wlv.ac.uk/~in5379/faq.htm
