TREATIES
»»NOTE: Current United States treaties are issued individually by the Dept. of State in "slip" form as the "Treaties and Other International Acts Series" (TIAS). Each is assigned a number ("TIAS [number]"). The State Department has later republished each treaty in the annual United States Treaties and Other International Agreements set since 1950.
Texts of treaties signed before 1950 can best be cited to a multivolume work compiled by Charles Bevans from 1968 to 1974 for the Dept. of State. (see below - "Treaty in compilation, pre-1950")
The APA Manual does not address treaty citations; the following examples are based on the general guidelines for legislative/legal materials. (See Bluebook, sec. 21.4, for the formal legal citation method.)
