"The present volume owes its existence to one of these conferences, viz. the International Conference on Grammaticalization Theory and Data, held at the University of Rouen in May 10-11, 2012 [which is the first quadriennial conference]. The purpose of this conference was to advance our knowledge on this type of language change through further general and theoretical explorations and through further empirical case studies. As a consequence of this program our volume is divided into a section dealing with general, theoretical aspects of grammaticalization and a section in which new case studies are presented."
