These lectures focus on the United Nations Convention on Contracts for the International Sale of Goods ("CISG"), a multi-lateral treaty that has been ratified to-date by 71 States and that has rightly been called the most successful commercial law treaty in history. The first of the two lectures examines the purposes, nature, history and scope of the CISG, as well as the ground-breaking web-based research infrastructure that has grown up around it. The second lecture explores the most important substantive sales law provisions of the CISG.
