[42] These suggestions are based on the comment of Major Martin Herz, who prepared the leaflets at Anzio beachhead and subsequently was leaflet expert at SHAEF.

[44] The Department of the Army is understood to be preparing a Field Manual and Technical Manual for Psychological Warfare which will describe the doctrines and the equipment, respectively, to be used in combat propaganda situations. [45] In the postwar period a great many reflective publications began to appraise what had happened in the PsyWar field. One of the best of these is Daniel Lerner's _Sykewar: Psychological Warfare Against Germany, D-Day to VE-Day_ (New York, 1949), which covers the European operation in detail. This was followed by _Propaganda in War and Crisis_, edited by Daniel Lerner (New York, 1951). A heavier work, covering many of the same problems is _The Language of Politics_, by Harold D. Lasswell, Nathan Leites and associates (New York, 1949). Leonard Doob's work on propaganda, long the leading American text in the field, was issued in a revised, postwar edition (New York, 1948); the postwar book does much to put "psychological warfare" in perspective. A simpler text than Doob's, useful for less advanced students, is Frederick C. Irion's _Public Opinion and Propaganda_ (New York, 1950). A manual directly pertaining to psychological warfare is _America's Weapons of Psychological Warfare_ edited by Robert E. Summers (New York, 1951); this also contains a bibliography which is helpful to the layman. Three outstanding works summarize the postwar propaganda position of the U.S. Government: Charles A. H. Thomson's _Overseas Information Service of the United States Government_ (Washington, 1950) shows the continuity of the problem from war to peace; Wallace Carroll's _Persuade or Perish_ (Boston, 1948) argues the necessity of maintaining an opinion offensive; and Edward Barrett's illuminating discussion, _Truth is Our Weapon_ (New York, 1953), brings the story down to the Eisenhower Administration.
