This month the United Nations re-launched its invaluable treaty research service, United Nations Treaty Collection, but at a new URL: treaties.un.org
And in addition, the American Society of International Law has launched a new free database entitled i-lex: The Legal Research System for International Law in U.S. Courts.
"This online database of select U.S. court cases and related materials is designed to serve as a practical resource for members of the judiciary and other legal professionals to identify and understand how international law is interpreted and applied by U.S. courts at both the federal and state level."
More work for guide updating...but great new resources!
