For those interested in Norman Fairclough's work--he has actually
published quite a bit . I recommend his books Language and Power,
Discourse and Social Change, and Media Discourse. They might be more
accessible than some of his articles.
Also for those interested in this topic--they might want to check on Jay
Lemke's book on Textual Politics. Fascinating stuff.
Actually running a search on Lemke's work will get you some intersting
material as he has published on the WWW.
