Commentary on the work of UNCITRAL from Professor Sanders always presents points of interest to the ever larger audience of practitioners, scholars and others interested in arbitration and other forms of alternative dispute resolution. In this second edition of his book on UNCITRAL's work1 Professor Sanders has supplemented his discussion of the 1976 UNCITRAL Rules with commentary on the 1999 IBA Rules on the Taking of Evidence in International Commercial Arbitration, which were only briefly noted in the first edition. He has added a topic reviewing the 1996 UNCITRAL Notes on Organizing Arbitral Proceedings and has supplemented his discussion of the 1985 UNCITRAL Model Arbitration Law with reference to the various additions made by enacting states and with a commentary on proposals for additions to the Model Law suggested for Commission consideration by the UNCITRAL Secretariat and certain further topics proposed by Professor Sanders himself. And he has expanded his discussion of the UNCITRAL Conciliation Rules with a detailed review of the 2002 UNCITRAL Model Law on International Commercial Conciliation. Although the reader may find himself in disagreement with Professor Sanders on this or that point, the calm authority and practical good sense with which he states his views will compel a thoughtful reaction.
