The World Treaty Index provides access to over 55,000 treaties of the 20th century, from sources ranging from the United Nations Treaty Series to various national indexes, gazettes, and official files. For those new to this database, please consult the field descriptions and search instructions before starting your search.

Beta version: The online version is in development, and we appreciate your comments about usability, which will help us convert the WTI from a tool that supports mediated searching only to one that is accessible to end-users. Comments can be sent to Glenda Pearson, Administrator, World Treaty Index, at pearson@u.washington.edu.
