Book excerpt: The twenty-two chapters of this volume elucidate the key themes of the fan studies vernacular. As the contributing authors draw from recent empirical work around the globe, the book provides fresh insights and innovative angles on the latest developments within fan cultures, both online and offline. Because the volume is specifically set up as companion for researchers, the chapters include recommendations for the further study of fan cultures. As such, it represents an essential reference volume for researchers and scholars in the fields of cultural and media studies, communication, cultural geography and the sociology of culture.
