The author evaluates in detail the costs and/or gains and the interference (positive or negative) in the commercial, public administrative, and social spheres that data protection laws have the potential to create, with numerous references to legislation and administrative decision making in a wide variety of jurisdictions.

This book promises to become a cornerstone in the new edifice of legal scholarship in this field. It will be of immense usefulness to lawyers, scholars, regulators and policymakers in this burgeoning area of the law.

Review(s) Bygrave's book ...helps to get the big picture of some of the most important principles that are embodied in the various data protection rules existing in Europe. Bygrave takes on the ambitious task of confronting several issues that the academic world has had trouble coming to terms with, one of which is trying to bridge the concepts of data protection and privacy. [...] This book will be helpful for privacy scholars, regulators, policymakers, lawyers, and generally anyone who is interested in comparative privacy issues."
