Public Relations Theory [PDF ebook] 

Beginning with the basic premise that public relations can best be understood as a specialized type of communication, the contributors to this volume establish public relations as a vital and viable realm for communication research and theory development. Through the application of communication theories, they attempt to explain and predict public relations practices and then use these practices to develop communication theories. Their discussions fall into three distinct categories: metatheory, theory, and examples of applications of theories. An ideal volume for professionals and students in communication, journalism, and related fields.
