The emergence of European Contract Law as a field of enquiry has been matched by a burgeoning literature. This includes textbooks, casebooks, monographs and commentaries as well as at least one journal and huge number of journal articles. As the field has matured, so has its elaboration and analysis by scholars, though it remains a field replete with contested viewpoints and many controversies. This new work by one of Germany's most well-known and respected private law scholars, seeks to present a complete and coherent view of the subject from the perspective of the jurisdiction which has arguably had more responsibility than any other for influencing the shape and content of European contract law.
