One of the most important characteristics of today's private law is that it increasingly flows from different sources: Next to national legislation and case law, it is also shaped by European and supranational sources and rapidly becoming a mixture of differently oriented rules and principles. This development can be described as one from coherence to fragmentation.

The aim of the new book is to consider how this important shift has worked out in different subfields of the law like in contract and property law, in competition, insurance, marketing and private international law as well as in the law of intellectual property. This cross-disciplinary approach shows how pervasive legal fragmentation has become, and points out how to remedy the adverse effects it brings with it. The volume is therefore indispensable for anyone interested in how Europeanisation affects national private laws.
