Primary research for this book involved the reading of complete runs of The Educational Screen, Business Screen Magazine, Film News, Sightlines, and Film Library Quarterly, which cover the history of the non-theatrical and educational film genres from 1922 through the present. For access to these and other research materials, I am grateful to the Margaret Herrick Library of the Academy of Motion Picture Arts and Sciences, the Louis B. Mayer Library of the American Film Institute, the Los Angeles Central Library, and the Doheny Memorial Library of the University of Southern California.
I would also like to thank Rudy Behlmer, Q. David Bowers, the Council on International Nontheatrical Events ( Joy Parisi), Layne Dreben, Robert Gitt, Hal Guthrie, Ron Hall, Pat and Steve Hanson, Kit Parker, Timothy M. Rogers ( Chairman of the Division of Cinema at Bob Jones University), and Noel Van Gorden ( Chief of the Burton Historical Collection at the Detroit Public Library). At Greenwood Press, I would like to thank Marilyn Brownstein, Arlene Belzer, and, this time also, Robert Hagelstein.
For his enthusiasm and help, I am particularly grateful to Thomas W. Hope, Chairman of Hope Reports, Inc.
