space in GR

[Umberto Mazzei]

Hi guys,
I'm working on a paper about spatial representations in postmodernist  
literature and part of it will be dedicated to GR and M&D. As regards  
M&D I've already found enough literature, while I have some problems  
in finding something specifically on the topic for GR (I'm looking,  
loosely speaking, for a close analysis to The Zone and the way in  
which space is depicted in the novel).
What I got so far is the chapter "In The Zone" in McHale's  
"Postmodernist fiction" and Brian Jarvis' chapter on P in his  
"Postmodern Cartographies". They're both useful, but I'd need  
something more.
Anyone can suggest essays about that?

Thanks in advance for your help!
cheers,
Umberto
