An authority in the field produces here a comprehensive, informed book on the relatively new profession of public relations. The author treats his subject in its four phases, - first the public at which programs are aimed; he analyzes the major groupings, the employs, the stockholder, the customer, the trade, the community and the political factions. The second section deals, somewhat superficially, with the fundamentals of public relations, the roles of research, policy and verbal expression. Thirdly comes detailed analysis of media, the press, radio, direct mail, motion pictures, signs, and the broader aspects of publicity as related to pressure groups, advertising, sales and education. The concluding section deals with the physical components of public relations, the agent himself, the staff, public relations counsel, and the departments in advertising agencies. Reliable, inclusive handbook.
