The Institutionalisation of European Spatial Planning aims to clarify the enterprise of European spatial planning. The emphasis of the book lies on the need for a better understanding of the process of European integration in general. It particularly points at the emerging middle range theories that used concepts that were showing similarity to those that academics - those writing about planning - were accustomed to, such as networks, discourses and governance. The focus of this book is mostly on the post-European Spatial Development Perspective (ESDP) - the Committee of Spatial Development - from 1999 until now. As it is collection of articles, it has a different gestation process and does not tell a story from A to Z. What this book is about, however, is merely the issue concerning the institutional capacity of the ESDP and whether this has evaporated or not. The fact that this book exists at all suggests it has not.
