The recently published book， Public Relations II， edited by Carl H.Botan and Vince Hazlton (2006)， comprehensively covered theoretical notions and research in the field of public relations. As promoted by the publisher， this updated edition， compared to its 1989 edition， is more of a new work than a revision because the editors brought together much broader variety of work by more public relations scholars with an intention to reflect advances or changes in the public relations academia since then. In short， this book have high aims: it hopes to document the current state of public relations research， serve as a comer stone for future development of public relations theories， and also demonstrate that our field is a solidly theory-driven， research-based discipline.
