Abstract: The longest running professional responsibility book on the market, Problems in Professional Responsibility for a Changing Profession has been thoroughly updated by its current and two new authors. It has retained its original problem-oriented focus on practical issues faced by lawyers in everyday practice, current issues faced by the profession, and its unique section examining the demographics, structure, and organization of the legal profession. The need of our profession to take account of our changing world is apparent in every chapter of the new edition.
