One place to start, though it's pretty dated now, is the filmographies at the back of WOMEN AND THE CINEMA: A CRITICAL ANTHOLOGY, ed. Karyn Kay and Gerald Peary (Dutton, 1977). There is some discussion of Dorothy Arzner, Ida Lupino and Maya Deren, et al., but of course it cannot cover the women who have been coming into film in the last two decades such as Penelope Spheeris, Martha Coolidge and Susan Siedelman. Also, don't overlook tv. There seem to be a rising number of women and minority directors in the medium. --Don Larsson, Mankato State U., MN
