This new book offers a fresh approach to teaching the law of sales of goods. Through precisely crafted problems, the book guides students through their own close textual analysis of Article 2 of the Uniform Commercial Code and then invites them to test their understanding by applying the Code to complex fact situations. Students learn how the Code works by actively parsing the language themselves and exploring the interpretational difficulties presented, rather than relying more passively on cases or explanatory text, which are included here only when necessary to furnish rules or interpretations not derivable by students' own close reading and analysis. With a primary focus on Article 2, the book also incorporates relevant material from Articles 1 and 7, and from related statutes such as the Magnuson-Moss Warranty Act, Uniform Electronic Transactions Act (UETA), and the federal Electronic Signatures in Global and National Commerce Act (E-Sign). It concludes with an assignment on the economic loss doctrine and the relationship between Article 2 claims and tort liability. The text teaches the doctrinal content of the law of sales of goods, while concurrently building students' skills in reading statutes critically and constructing legal solutions to complex problems. The format keeps students actively engaged in analyzing statutory provisions and formulating answers. They will emerge from the process with a deep understanding of the Code, and with the skill to read any statute---including any amendments to Article 2---more effectively. The book is accompanied by a Teachers' Manual containing the authors' solutions for each of the problems in the text. If the Article 2 revision process results in the adoption of amendments to Article 2, a supplement will be available with additional problems based on the new provisions.
