I have been teaching the United Nations Convention on Contracts for the International_x000D_ Sale of Goods (11 April 1980, 1489 U.N.T.S. 31, 19 I.L.M. 668 (entered into force 1 January 1988, ratification by Singapore 16 Feb 1995) [CISG]) for 20 years, first at McGill and then at the National University of Singapore. At first there was no short textbook I could recommend to students.
