The third edition of this concise book is mainly intended to be used as an introduction to the rules of private international law belonging to the legal system of the European Union. It provides legal practitioners with an overview of this highly complex field of law and can serve as an introductory textbook in elective undergraduate courses and master programs offered by many law schools, both to their own students and to exchange students from other countries. The book will also be useful as a springboard towards more profound studies of statutory texts, case law, and legal literature.
