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. --Don Larsson, Mankato State U., MN
