John W. Meyer's work broke new grounds in institutional thought in sociology and made him a central thinker for the emerging interdisciplinary field of neo-institutionalism, while at the same time establishing institutional thought's comparative variant, world society theory. His scholarship plays a prominent role in contemporary social theory, and has shaped research areas such as international relations and globalization, organization theory, and management studies. One of the results of Meyer's wide-ranging and interdisciplinary influence is that his work has appeared in a diverse range of outlets. This book brings together some of John W. Meyer's widely-scattered work, reviewing four decades of scholarship, and adding several original pieces from Meyer's current work. It gathers substantive commentary on social processes, from stratification to globalization to socialization, as well as on key social institutions, from science to religion to law to education. In its expansive review, this book is both about neo-institutional thought in general and world society theory in particular. This book is both by John W. Meyer and about John W. Meyer: to the compilation of Meyer's canonized and current work, Georg Krücken and Gili S. Drori add an essay on the theoretical and empirical contribution of Meyer's institutional theory, placing it within the broader context of contemporary social theory, globalization research, and organizational studies in both in the United States and Europe.
