This timely collection addresses central issues in communication theory on the nature of organizing and organization. It contributes to the conception of materiality, agency, and discourse in current theorizing and research on the constitution of organizations. Representing scholarship in various parts of the world, it features contributions that overcome traditional conceptions of the nature of organizing by addressing the difficult issues of the performative character of agency; materiality as the basis of the iterability of communication and continuity of organizations; and discourse as both textuality and interaction.
