A short list of authors worth a look:
Harry Harrison, Bob Shaw, Poul Anderson, Gordon R Dickinson, William Gibson , Philip K Dick, Dennis Wheatley.
As for books heres some random tiltles i remember:
1984, Farenheit 451, Make Room Make Room, The Final Programme, The Rock and Roll Invasion, The Turin Option.
