It is also possible to retrieve the full texts of U.S. treaties and other international agreements from several unofficial, commercially published sources. These unofficial sources are described in the table below. Bear in mind that when citing a treaty, it is preferable to cite to an official source, rather than an unofficial source.
In addition, U.S. treaties and other international agreements are available in full-text on Lexis and Westlaw. Both platforms assign their own in-house citation numbers to recent treaties and agreements. However, you won't find Lexis and Westlaw treaty numbers in treaty indexes. If you have a citation to an official source, such as T.I.A.S. or U.S.T., you can use it to retrieve the full text of the treaty on Lexis and Westlaw.

|Treaties and Other International Agreements of the U.S. (Bevans)
This compilation includes U.S. treaties and agreements that entered into force prior to 1950. Usually referred to as "Bevans" for the name of its editor. Volumes 1-4: multilateral treaties and agreements arranged by date of signature. Volumes 5-12: bilateral treaties and agreements arranged alphabetically by treaty partner. Volume 13: cumulative country and subject indexes. Supersedes two prior compilations: Malloy (1778-1937) and Miller (1778-1863). (Note that The Bluebook classifies Bevans as an unofficial source for citation purposes, even though it was published by the Government Printing Office.)
