This book is based on my PhD thesis, the final version of which benefited from the support and helpful comments of numerous colleagues and friends. I wish to thank first and foremost my PhD supervisors Bernt Hugenholtz and Deirdre Curtin, who invested so much of their time and patience in my research. Special thanks and gratitude go to Lucie Guibault, my daily advisor, whose availability and support were beyond words and who was a true friend in times of need. I would also like to thank all my colleagues at the Institute for Information Law and the Amsterdam Centre for European Law and Governance, namely, Angela Moisl, Anja Dobbelsteen, Egbert Dommering, Gerard Mom, Jan Kabel, Joana Mendes, Mireille van Eechoud, Natali Helberger, Nico van Eijk, Ronald van Ooik, Rosanne van der Waal, Stef van Gompel and Tarlach McGonagle. A special word of appreciation goes to Annabel Brody, for proofreading the entire document, and to Bala´zs Bodo and Joost Poort, for providing me with very helpful insights regarding social sciences’ methodologies.
