This book contains the updated papers of the 5th Annual MAA Peter Schlechtriem CISG Conference, which was held in March 2013 in Vienna. The focus was on the nature of the borders of the CISG: with other laws, with other unification efforts, and how far the CISG might stretch to newer developments in business.
