New Category System: The Treaty Office has been working to streamline and update the category system by which it organizes treaties and agreements.  Treaties in Force 2018 features this new category rearrangement, which we hope will make agreements easier to locate by topic. This new system will be used across all treaty publication platforms managed by the Treaty Office (Treaties in Force, Treaties and Other International Agreements (TIAS) publications, and website searches). To aid with the transition, we have created this category crosswalk, which lists new categories alongside their older counterparts.

Arrangement

Treaties in Force is arranged in two sections. Section 1 includes bilateral treaties and other international agreements listed by country or international entity, with category headings under each entry. Arrangements with territorial possessions of a country appear at the end of the entry for that country.  In some cases, treaties and international agreements applicable to a territory prior to its independence are included in the entry for that country.  For convenience, some treaties and agreements concluded with countries whose name or statehood status has changed continue to be listed under the name in use at the time the agreement was concluded, unless the title of the treaty or agreement has been formally amended.

Section 2 lists multilateral treaties and other international agreements to which the United States is a party, arranged by category. A comprehensive list of parties to each agreement as of a certain date is provided.  The depositary is the authoritative source for a current list of parties and information on other matters concerning the status of the agreement, and status information often changes.  Information is provided on the depositary for the agreement in question, and contact information, including an Internet site, is provided for the depositary where available.
