OUP has performed another update of the Max Planck Encyclopedia of Public International Law, adding another 61 articles to the online edition. Here is a short description of the last update:
The May 2010 upload of new articles includes 13 entries from the International economic law and relations subject area. Highlights include articles on State Bankruptcy, ICSID, NAFTA, Regional Trade, and MERCOSUR. There are also a significant number of new articles on the use of force, including those on Nuclear Weapons and Warfare, and Collective Security.
The next upload will be in August 2010.
Thanks to Nik Speller for drawing my attention to this.
