There are many good reasons to present a book on the functioning of representative democracy at this precise moment. But the true reason for its creation is a special event of a personal nature: the formal retirement of Jacques Thomassen at the University of Twente. In his long and impressive academic career Jacques Thomassen has greatly contributed to the study of democracy. He has authored and edited several influential academic works, which already started with one of his first articles in 1976, entitled “Party identification as a cross-national concept,” which is still considered to be a classic in the literature on voting behavior. His publications since include many books in both Dutch and English, often published by the leading academic publishers in political science. His reputation as an editor of books is almost unrivalled in political science. But there is much more. Jacques Thomassen has played a vital role in the development of major national and international data collection projects about political institutions, such as the Dutch Parliamentary Election Studies, Dutch Parliament Studies, Comparative Study of Electoral Systems and the European Election Studies. The data that are still generated on the basis of these collaborative projects provide a most valuable source of information for the study of democracy – without it researchers would arguably not be able to adequately study the functioning of democracy – and thus form one of the most important developments in the last decades in political science.

This Liber Amicorum serves to honour Jacques Thomassen for his extremely valuable contribution to the study of democracy. In his career he has collaborated with dozens of academics from many countries. They have learned to know Jacques Thomassen as a most competent and erudite scholar and a good colleague; and many enjoy the privilege of being amongst the many friends that he has made over these years. This volume is a collection of essays by some of these colleagues and friends. In planning this volume, we had to be very restrictive, and as a result many colleagues who would have liked to contribute to this book could not be taken on board.
