Congress.gov provides access to Senate Treaty Documents, which include the full texts of treaties submitted to the U.S. Senate for ratification, from the 90th Congress (1967-1968) onward. (Senate Treaty Documents from earlier congresses are gradually being added.) Search by Treaty Document number or browse by congressional term, treaty status or subject.

|U.S. Is NOT a Party||Electronic Information System for International Law (EISIL)
EISIL is a convenient gateway for accessing major multilateral treaties, whether or not the U.S. is a party. If you know the name of the treaty, use the Advanced Search and restrict your search to the title field. Or browse by subject. Click on "more information" below the name of each treaty to view its date of signature, date of entry into force, authentic languages, and citation information. Cautionary Note: The EISIL database is in the process of being updated and migrated to a new platform. Many links to the full texts of treaties are temporarily broken. If you encounter a broken link, you can still use the citation information provided to retrieve the treaty from a full-text source.
