This article explains the history of the materials (long unpublished) that became the contracts casebook: Macaulay et al., Contracts: Law in Action. In the early years we worked closely with Ian Macneil, another pioneer of relational contract thinking. And we contextualized our cases, reflecting a law in action perspective. We identify five themes as providing a structure to the materials: (1) Incorporating UCC Article 2 into the contracts course; (2) Remedies first; (3) Law in Action; (4) Relational contracts; and (5) Contracts are everywhere.
