Updated: Note for 2014/2015: The Department of State will not publish a full edition of Treaties in Force for 2014 or 2015 due to continuing efforts to update information technology and treaty records used by the Office of Treaty Affairs. In place of full 2014 and 2015 editions, the Department is publishing an electronic supplement listing treaties and agreements that have entered into force for the United States since January 1, 2013, along with a small number of agreements that entered into force prior to January 1, 2013 but which were inadvertently omitted from the 2013 edition. The information contained in the Foreword of the 2013 edition regarding the arrangement and scope of the material contained there also applies to the material contained in this supplement. We regret any inconvenience users of Treaties in Force may experience from the absence of full 2014 and 2015 editions. The Department expects to publish a full edition of Treaties in Force in 2016.
New Category System: The Treaty Office has been working to streamline and update the category system by which it organizes treaties and agreements. The new supplement and Treaties in Force 2016 will feature 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.
Treaties in Force is arranged in two sections. Section 1 lists bilateral treaties and agreements sorted by country or international entity, with subject headings under each entry. Arrangements with territorial possessions of a country appear at the end of the entry for that country. Treaties and international agreements applicable to a territory prior to its independence are included in the entry for that country. 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 arranged by subject. A comprehensive list of parties to each agreement as of a certain date is provided. However, we note that a depositary for a treaty 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. Links to depositary websites are provided, whenever possible.
