This Fourth Edition retains the original's incisive article-by-article commentary, as well as its insistence on how the parties' duties and the corresponding remedies need to work together ('like scissor-blades, ' to quote Professor Honnold's vivid simile) and the many concrete examples that illustrate and test the Convention's response to problems that arise in international trade. It deals definitively with the crucial aspects of sales contracts, including the following, taking fully into account the myriad variations among distinct legal systems: delivery of the goods and handing over of documents; conformity of the goods and third party claims; remedies for breach of contract by the seller; payment of the price; taking delivery; remedies for breach of contract by the buyer; anticipatory breach and instalment contracts; damages; interest; exemptions; effects of avoidance; and preservation of the goods conclusion ( formation) of contracts.
