Continental European legal scholarship witnesses a trend towards more interdisciplinary research. This trend raises numerous questions: What do legal scholars mean when referring to the concept of interdisciplinarity? Is it possible to distinguish different types of interdisciplinarity? What are the functions of interdisciplinary arguments in legal debates? Are there common problems which legal scholars face when engaging in interdisciplinary research? Is there an interdependence between a given national legal system and interdisciplinary research? Despite the trend towards more interdisciplinarity in legal scholarship, it seems that these and related questions have hitherto not attracted much attention. The present volume explores these questions using a bottom-up approach, offering reflections by legal scholars on interdisciplinary legal research in their fields of expertise.
