White and Brunstad's Secured Transactions: Teaching Materials, 4th deals with both the basics of secured transactions under Article Nine of the UCC and some of the most complex modern transactions such as "repos" and "securitizations." To offset the complexities of the subject matter, the authors have made this text extremely user-friendly. Every chapter has extensive expository introductory material to help the student get oriented. This manageably sized book is organized by transaction (e.g., loans on equipment, loans on inventory, etc.), rather than by code section (e.g., attachment, perfection, etc.), so that students can see how various transactions develop, rather than learning about sections of the code out of context. A course on Article Nine offers the opportunity for the student to acquire an extensive and vitally important commercial law vocabulary, and this book maximizes that opportunity. In addition to extensively revising all of the former chapters, the new edition adds a new introductory chapter on the history of secured transactions and the interpretation of Article Nine (including use of the official comments), and a concluding chapter on the theory of Article Nine. This tracks modern curricular trends, including increased interest in courses on legislation and more detailed consideration of methods of statutory interpretation.
