This 4th edition continues and advances the pedagogical strengths of earlier editions. We knew that the 4th edition needed to be different from the 3rd because law is evolving. Certain areas of business law experience recurring re-examination and revision. For example, we created new material for this edition, emphasizing privacy, cyber and immigration law. In addition, each author pledged to refresh our chapters with recent developments in business law. Future business leaders need knowledge of existing business law as well as a set of skills permitting them to adjust efficiently and effectively to new legal issues as they arise over the course of their careers. We are excited about the contents of our features and want to explain the function of each of them in preparing students for leadership positions in business.
