World Treaty Index (WTI) is a new database that aspires to contain every known international agreement of the 20th century by January 2011 -- over 85,000 treaties!  At the moment there are about 53,000 agreements.

This new database will eventually allow the user to calculate histograms on the fly, perform combination searches (by topic, country, etc), merge with other datasets (using the Correlates of War codes), and download all or part of the data in a .csv file.

I just did a search for treaties between Argentina and Uruguay and got 63 results between 1945-1990 with citation information where available (this is not a full-text database). The results tell me what type of treaty (bilateral or multilateral), the date of the treaty, the topic, and the title in English.  What a resource!

Both the website and topic codes build upon the work of Peter Rohn from the University of Washington who conducted the original WTI collection process in the 1960's and 1970's.

We now have IP access to Global Arbitration Review, one of the leading sources of information for international arbitration professionals.  This is a subscription for the Yale community and requires a VPN connection off-campus.

The URL is: http://www.globalarbitrationreview.com/  

In addition to having access to the electronic version of the print GAR journal, the GAR website also provides news, surveys, and interviews targeted for the arbitration professional.

The invaluable and immense three-volume study on customary international humanitarian law conducted by the International Committee of the Red Cross (ICRC) and published by Cambridge University Press in 2005 is now available free online:  http://www.icrc.org/customary-ihl/eng/docs/home.  I have used this work to find, for example, relevant sections of a foreign country's military manual.

The Study has two parts:

1. Rules - a comprehensive (but not exhaustive) analysis of the customary rules of international humanitarian law identified by the Study and considered to be applicable in all armed conflicts.
   
   
2. Practice - for each aspect of international humanitarian law covered, a summary of relevant state practice including military manuals, legislation, case law, and official statements; practice of international organizations, conferences, and judicial and quasi-judicial bodies.

We have this work in print here:  http://morris.law.yale.edu/record=b591517~S1.

A complementary work, Perspectives on the ICRC Study on Customary International Humanitarian Law, is here: http://morris.law.yale.edu/record=b668444~S1.

 "Perspectives on the ICRC Study on Customary International Humanitarian Law results from a year-long examination of the Study by a group of military lawyers, academics and practitioners, all with experience in international humanitarian law. The book discusses the Study, its methodology and its rules and provides a critical analysis of them. It adds its own contribution to scholarship on the interpretation and application of international humanitarian law."

The ICRC has two other databases:

1. Treaties - contains treaties, commentaries, and other documents related to international humanitarian law: http://www.icrc.org/ihl.
   
   
2. National Implementation - provides documentation and commentaries concerning the implementation of international humanitarian law at the national level: http://www.icrc.org/ihl-nat.
