This book reflects the authors' belief that to teach only the rules would give students a false sense and static understanding of what commercial law is all about and what makes it exciting. This book is also an effective platform for a more detailed approach to the rules of commercial law. Problems could be easily supplemented text to provide students with a more technical understanding of these rules. The authors emphasize some of the rules because those rules help students understand the basic concepts. Most of the study deals with the UCC, specifically Articles 9, 3, 4, and 5.
