Editors Christopher T. Conner, Nicholas M. Baxter, and David R. Dickens have done us a great service by publishing this volume on important theorists that, as its title suggests, have been largely left unread and underappreciated. I hope the book is picked up by advanced undergraduates planning for graduate school, current graduate students focusing on social theory, and faculty looking to add to or modify existing theory courses. Instructors can assign the full text or add value to their courses by selecting some chapters while recommending the rest. Perhaps teachers looking to move beyond Marx, Weber, Durkheim, and Du Bois in classical theory will focus on the first part, while those teaching contemporary theory will pick up the latter. Each audience will find much to appreciate here, as the book whets the appetite for more from these founders and more recent theorists.
