Book excerpt: Organizational communication as a field of study has grown tremendously over the past thirty years. This growth is characterized by the development and application of communication perspectives to research on complex organizations in rapidly changing environments. Completely re-conceptualized, The SAGE Handbook of Organizational Communication, Third Edition, is a landmark volume that weaves together the various threads of this interdisciplinary area of scholarship. This edition captures both the changing nature of the field, with its explosion of theoretical perspectives and research agendas, and the transformations that have occurred in organizational life with the emergence of new forms of work, globalization processes, and changing organizational forms. Exploring organizations as complex and dynamic, the Handbook brings a communication lens to bear on multiple organizing processes.
