The ""principles, practices and tools of public relations"" by an experienced practitioner. The basic facts of the field, knowing yourself, knowing other people, interviewing, creating good will, selling, cementing employee and stockholder relations, the use of surveys and questionnaires, advertising, publicity and propaganda, etc. Additional guidance through the precepts of Elmo Roper, Gallup, Henry Link, Ivy Lee, etc.-- I thought this profession had been well covered; in the event that I'm wrong, here's another, adequate vocational manual.
