There's an overview of developments in David Cook's HISTORY OF NARRATIVE
FILM (2nd ed.), pp. 615-616.  Also check the newly released FILM HISTORY:
AN INTRODUCTION by Kristin Thompson and David Bordwell.  The latter has
excellent bibliographies, but I don't have page numbers at hand.
One source that's a must for research but most likely found in academic
libraries is THE FILM LITERATURE INDEX.  You should be able to find
individual articles indexed year by year, although there is some inevitable
lag time.
