What is public relations? What do public relations professionals do? And what are the theoretical underpinnings that drive the discipline? This handbook provides an up-to-date overview of one of the most contested communication professions. The volume is structured to take readers on a journey to explore both the profession and the discipline of public relations. It introduces key concepts, models, and theories, as well as new theorizing efforts undertaken in recent years. Bringing together scholars from various parts of the world and from very different theoretical and disciplinary traditions, this handbook presents readers with a great diversity of perspectives in the field.
