First published in the wake of World War II (1948), Linebarger's Psychological Warfare is the primary introductory text on the use of overt and covert propaganda, still used today by students and researchers. It was updated in 1954 as the author grappled with the implications of the Cold War. This enhanced hardcover edition includes both the original 1948 text and the additional chapters of the second edition, along with a new introduction with biographical details by Joseph A. Dixon.
