This book is a collection of essays around the concept of anonymity, both online and in the real world. Some essays are scientific studies of some aspect while others are to be classified more as art. The e-book is licensed under creative common (BY-NC-SA 4.0)

Over all the essays are interesting, thought provoking and engaging and well worth reading if the topic is of interest. I would however recommend readers to skip essays that are of less interest.
