This book was originally published in 1939, although it was reprinted in 1972. It's a very interesting analysis of propaganda, using a priest named Father Coughlin who had a radio show during the time, and who was basically a Facist.
The book discusses the various facets of what propaganda is and how those facets are used, and then analyzes a speech by Father Coughlin, showing how he used the various facets in his speech.
It's an interesting book, and the material on propaganda still holds. I don't know, though, why it was reprinted in 1972, as the entire book is geared around Father Coughlin who was no longer relevant in 1972.
