If you want to look at style, then the real peaks of the 20th century were Joyce's Ulisses and Steins' the Making of Americans. These are both early 20th cent. For the latter half, the snow has most probably not yet settled, but my personal fav is Powell's 12 volume Dance to the Music of Time.

None of these should be emulated by anybody.

However, a good way of getting something our of your system is to try to write 'in the style of' for a set period of time - say a month or so. Then go back and read what you've written in comparison to the ideals : - )

Good luck all!
