Kaufman and Wilkins mark the 20th anniversary of Problems in Professional Responsibility for a Changing Profession with a new 5th edition. Their new edition covers judicial, legislative, and executive developments in the traditional fields of conflicting interests and confidentiality, specialty fields of corporate and government representation as well as representation of those with impaired capacity. It also deals with the problems created by the increasing nationalization and internationalization of law practice, including the basic problem of trying to determine whose professional responsibility law governs the activity of lawyers when they engage in activity beyond their home jurisdictions. Various efforts to reform the profession here and abroad to meet the legal needs of clients and would-be clients are also presented. The authors have added substantial new material dealing with the demographics and institutions of law practice and their effect on professional identity.
