Statutes at Large
An official compilation of the acts and resolutions of each session of Congress published by the Office of the Federal Register in the National Archives and Record Service.
The Statutes at Large are divided into two parts: the first is composed of public acts and joint resolutions; the second includes private acts and joint resolutions, concurrent resolutions, treaties, proposed and ratified amendments to the Constitution, and presidential proclamations. Volumes from 1951 to the present are arranged by public law number; older volumes are arranged by chapter number.
The Statutes at Large are considered the official publication of the law for citation purposes when titles of the United States Code have not been enacted as positive law.
