Theory of Collective Behavior
by Neil J. Smelser
A modern edition of a sociological and social psychology classic, adding a reflective new Preface by the author--plus an extensive, analytical 2011 Foreword by MIT's Gary Marx. Marx notes, "The book is elegant, original, carefully crafted and forcefully argued. In its totality, it is a fine example of an effort to define a field, identify major types and systematically connect central variables."
