HeinOnline is pleased to offer a comprehensive collection of all United States treaties through the U.S. Treaties & Agreements Library. This valuable database includes every treaty to which the U.S. has been a party, whether currently in force, expired, or not-yet officially published—this includes those treaties and agreements between the U.S. and Native American tribes. With nearly 1,200 titles and 1.2 million pages, this database includes prominent collections such as the United States Treaties and Other International Agreements set (commonly referred to as the “Blue Set”), as well as famous sets from Bevans, Miller, Malloy, and others. 

In addition to being a complete source for the full-text of U.S. treaties, this resource includes hundreds of congressional hearings and related books, as well as numerous treaty guides, indexes, and other treaty publications.
