Entertainment: The Age of the Silent Feature Picture 1915-1928"
by Richard Koszarski (University of California Press,
1990, 395 pages.)
Somewhat of a mix of a reference work and a history.
Excellent information, and some different information that you
won't find elsewhere such as trends in theatre attendance, production
costs, etc. Chapters on the technology and making movies as well
as the filmmakers and stars. Third volume in a "History of
the American Cinema."
