Members of the Institute for Propaganda Analysis will note that some of the factual material in this book is derived from previous publications of the Institute. All students of propaganda will recognize our reliance upon the major works dealing with the subject; but particularly upon Walter Millis' Road to War, Harold D. Lasswell's Propaganda Technique in the World War, H. C. Peterson's Propaganda for War, and, in a somewhat different sense, Adolf Hitler's Mein Kampf.
The authors were immeasurably helped by the advice and patience of Eugene Davidson of the Yale University Press; the coöperation of Clyde R. Miller, executive secretary of the Institute for Propaganda Analysis; the research and technical assistance of Anne Simmons, Doris Wolson, Janie McDowell, and Eunice Carmichael; and the constant encouragement of Violet Edwards Lavine and Nancy Fraenkel Wechsler.
