This collection of papers has been crafted by students of Adrienne Héritier in honour of her 70th birthday on June 29, 2014 and her official retirement from the European University Institute in Florence. We would like to use this occasion to thank and commemorate her for the extraordinary work she has done for thestudy of political science in general and for us, her students, in particular. The papers in this collection were presented at the Kolleg-Forschergruppe (KFG) conference, ‘Perspectives on European Governance in Comparative Perspective: Interests, Institutions and Policy-making’, at Freie Universität in Berlin on July 4and 5, 2014. The papers aim at encapsulating the versatility of Adrienne’s scholarship by addressing core themes regarding ‘EU Governance’, ‘Policy Analysis’, and ‘Regulation and Governance’. A number of acknowledgements are appropriate regarding the birthday conference and this collection. First, we wish to recognize the team assisting Tanja Börzel who organized the conference and edited the Festschrift. Special thanks go to Luisa Linke and Katja Pomianowicz. Second, we would like to extend our gratitude to the funding bodies which made the event and collection possible: the Kolleg-Forschergruppe (KFG) “The Transformative Power of Europe” at the Freie Universität Berlin, the Centre for European Politics at the University of Copenhagen, and the Chair of Empirical Theories of Politics at the Ludwig-Maximilians- Universität München. Third, we thank the participants, the paper givers, the discussants, and the chairs at the conference.
