ABSTRACT
No serious student of democracy has been able to conduct work on the empirical theory of democracy since Tatu Vanhanen first began publishing his compilations of data without making reference to that work. The material contained in this collection of monographs, books and papers provides the raw data upon which so many of us rely for our work. Moreover, the collection of historical material, taking us back to the middle of the last century in a number of cases, is a unique resource, found nowhere else.
