Finding Treaties

Since there exists no complete collection of treaties in print or online, you must often conduct your research with a certain amount of creativity and perseverance, specially if you do not have a treaty citation. It is important to note that treaties may be referred to by variety of names (Agreements, Conventions, Protocols, Memorandums of Understanding, Exchanges of Letters, et cetera). This entry is designed to aid you in your treaty research.

Comprehensive Treaty Indexes

  • Bowman and Harris, Multilateral Treaties: Index and Current Status. Provides the date of conclusion, location, entry into force, duration, reservations, language of authentic texts, depository responsibility, eligibility of parties, list of parties, territorial scope, amendments, signatories and notes. This index provides more parallel citations than the other indexes. There is a keyword and subject index. Unfortunately the annual cumulative supplement, although arranged chronologically, is not indexed. ILS RR and ILS Ref Desk JX 171 .B68x 1984
  • Hein’s U.S. Treaty Index on CD-ROM. (see previous section)
  • Hein’s United Nations Master Treaty Index on CD-ROM. Provides a cumulative index for citations to international treaties and agreements published in the United Nations Treaty Series (UNTS). It presents the advantages of both indexing more recent volumes and of a growing cumulation of entries. However, given the slow pace of publication of the UNTS volumes themselves, coverage dates are still unavoidably slow.
  • Multilateral Treaties Deposited with the Secretary General.. Treaties are listed by broad subject areas. Information is provided on signatures, accessions, notifications, reservations, and declarations. The texts of declarations and reservations are reproduced. Latest developments are reported in the U.N. Chronicle (ILS JX 1977 .A1 U564). ILS and ILS Ref Desk JX 236.5 .M84

  • TIARA (see online resources below)
  • Treaties in Force (TIF). Indexes bilateral and multilateral treaties of the United States and gives citations to the texts. Treaties which are in force for the United States as of January first of a particular year are listed. TIF is updated by the State Department Dispatch and tends to run approximately a year behind schedule. ILS and ILS RR JX236.5 .T7
  • Some treaties may be included as the appendix of a work.

See section on “Online Databases” for additional sources.

Online Resources

Electronic resources will often be more up-to-date than print collections. However, authenticity may remain unsure in this somewhat unstable format. Some treaties, such as NAFTA and GATT, for example, have been put online by a variety of hosts. It is important to try to gauge their authenticity as best you can. A misspelling of “Tarrifs” in GATT or the fact that the entire title of a treaty is not included are examples of warnings.

  • TIARA. TIARA contains U.S. treaties and international agreements in force since 1783. This database contains specific fielded data and the full-text of over 10,000 bilateral and multilateral treaties signed by the United States.
  • From the start menu on any public terminal in the Harvard Law School Library, go to the Selected International Law Sources.” Click on “Treaties and International Agreements Online” and follow the instructions.
  • The UN Treaty Collection is the largest single collection of treaties on the internet. Approximately 30,000 treaties and related actions already published in the 1,450 volumes of the UNTS are available in English, French and any other authentic language used. Treaties can be located with relative ease using such information as type of agreement, date of signature, entry into force, names of the parties, and popular names.


  • The INTLAW library BDIEL file contains treaties on international trade, international finance, foreign investment, international arbitration, intellectual property, GATT, and the U.S.-Canada Free Trade Agreement.
  • ILMTY includes treaties and other international agreements published in International Legal Materials.
  • The FEDTAX library IBFDTR file contains U.S. tax treaties.
  • The file TNIMAG provides tax treaty updates for all new and pending treaties from Tax Notes International Magazine.
  • The ECTY file includes European Community Treaties.
  • The SENATE file in the GENFED library is useful for locating any reservations to a recently ratified treaty.


  • The USTREATIES database provides complete full-text coverage of international and Native American treaties to which the United States is a party from 1778 to present. Some useful fields for searching this database are: CTR for COUNTRY NAME -Foreign country that is party to the document; and SI for AUTHOR -Name and title of all designated signers, if available. As many texts are loaded before official UST and TAIS citations are available, Westlaw citations (e.g. 1993 WL 82993) can be used instead.
  • The IEL database (International Economic Law Documents) contains documents selected by the International Economic Law Interest Group of the American Society of International Law. It includes the texts of international agreements. Once you have chosen the database, to view its Table of Contents, enter the query: ci (contents). The Environmental Law Reporter (ELR) includes the treaties portion of the Environmental Law Reporter Statutes binder. Federal Taxation International Acts (FTX-IA) includes tax agreements between the United States and foreign governments.
  • Westlaw also provides information for locating citations to treaties or information about recent treaties by using the full-text law reviews and newspaper sources. A useful place to look is INT-NEWS which contains documents from newspapers, magazines, journals, newsletters, transcripts and wire services from around the world. This resource would rarely produce the full text of treaties but rather information and commentary about them.
