Using twelve histories of micro-dimensions of communication studies, this volume shows how sometimes small decisions, single scholars, individual departments, and marginalized voices can have dramatic roles in the history and future of an academic field. It offers rich detail, missing links, and local narratives that fully flesh out the communication studies discipline. No education in communication studies is complete without an understanding of the themes, challenges, and triumphs embodied by the twelve micro-histories offered in this book. This book was originally published as two special issues of Review of Communication.
