This is a comprehensive 986-page casebook on Contract Law (July 2025 version). It covers all the major topics typically taught in first-year Contracts courses at American law schools. Volume I addresses contract formation and it covers consideration, offer and acceptance, and defenses to formation. Volume II begins with topics related to contract content (interpretation, gap-filling, and the duty of good faith), moves to performance and breach, addresses remedies, and concludes with a discussion of third-party rights.
