This law school textbook uses precisely crafted problems, allowing students to actively parse the language of Article 2 of the Uniform Commercial Code (UCC) themselves, rather than relying more passively on cases or explanatory text. Cases and other material are included when necessary to furnish rules or interpretations not derivable by students' own reading and analysis. The book also incorporates relevant material from Articles 1 and 7, and from related statutes such as Uniform Electronic Transactions Act (UETA), the federal Electronic Signatures in Global and National Commerce Act (E-Sign), and an assignment on the economic loss doctrine.
