This best-selling supplement contains materials that can be used with any contracts casebook. This edition has received a significant makeover while retaining the basic, popular features. Most notably, it now includes short annotations that introduce each selection. These annotations put each selection in context by explaining its origins, central purpose(s), scope of application, and current legal status. Students will better understand the selection's point, purpose, and content; and teachers will have less need to explain an assigned selection's context. In addition, the authors have thoroughly updated the content. It includes excerpts from the brand new Restatement (Third) of Restitution and Unjust Enrichment, reference to the 2010 amendments to relevant parts of UCC, Article 9, and the 2010 amended version of the Bankruptcy Act, 24 (on subsequent promises to pay debts discharged in bankruptcy). The Tables of Comparisons, which identify counterpart provisions of the UCC, CISG, UNIDROIT Principles, and Restatement (Second) of Contracts, has been updated by replacing citations to the prior version of UCC, Article 1 with citations to the revised version; forty states now have enacted the latter. The new annotations, conjoined with its inclusiveness, currency, and convenience, provide a significant comparative advantage over competing volumes and materials.
