external relations, and the new areas of competence are omitted, which, given the size of the undertaking, is sensible. The second edition incorporates changes in format which will undoubtedly be welcome, such as an alphabetical index of cases to supplement the chronological table, and a list of suggested reading material at the end of each chapter.
Indeed, whatever the limitations placed on the academic content of the book by the decision to cover so much in such a limited space, it is clearly a textbook which is highly successful amongst students, and which no doubt will continue to be very much in demand.

Students of EEC competition law will welcome the fourth edition of Professor Valentine Korah "'Little Yellow Book'", now well established as a leading introductory guide to this area of the law. Originally conceived as an aid to those engaged in business to explain when the advice of a lawyer would be necessary, the latest edition appears to be written more with the student or practitioner in mind, particularly one approachaing this area for the first time. Professor Korah, now assisted in this edition by Warwick Rothnie, has taken into account developments up to July 1990 but retains the clarity and succinctness of exposition so characteristic of her previous work. The essential merit of this guide remains that it is written from a business point of view.

It is not the kind of report any student would relish taking home!
Merger control is as yet in its infancy at the EC level. The guide has been able to take into account the Merger Regulation and its associated notifying Regulation and notices, but not the Commission's Decision in Douwe Egberts/Van Nelle which has pointed up some of the practical difficulties which will be encountered in assessing thresholds. This is no doubt one of several areas which will require further clarification from the Commission, if not the Court, if one-stop merger notification is to become a reality.
Despite the lack of indication of how the Commission is going to exercise its new won powers Korah presents an admirable summary of the control regime. She explains the difficulties in determining whether a joint venture is
