In the law of the United States, the Code of Laws of the United States of America (variously abbreviated to Code of Laws of the United States, United States Code, U.S. Code, U.S.C., or USC) is the official compilation and codification of the general and permanent federal statutes. It contains 53 titles (Titles 1–54, excepting Title 53, which is reserved for a proposed title on small business). The main edition is published every six years by the Office of the Law Revision Counsel of the House of Representatives, and cumulative supplements are published annually. The official version of these laws appears in the United States Statutes at Large, a chronological, uncodified compilation. Codification Process The official text of an Act of Congress is that of the "enrolled bill" (traditionally printed on parchment) presented to the President for his signature or disapproval. Upon enactment of a law, the original bill is delivered to the Office of the Federal Register (OFR) within the National Archives and Records Administration (NARA). After authorization from the OFR, copies are distributed as "slip laws" by the Government Publishing Office (GPO). The Archivist assembles annual volumes of the enacted laws and publishes them as the United States Statutes at Large. By law, the text of the Statutes at Large is "legal evidence" of the laws enacted by Congress. Slip laws are also competent evidence. The Statutes at Large, however, is not a convenient tool for legal research. It is arranged strictly in chronological order; statutes addressing related topics may be scattered across many volumes. Statutes often repeal or amend earlier laws, and extensive cross-referencing is required to determine what laws are in force at any given time. The United States Code is the result of an effort to make finding relevant and effective statutes simpler by reorganizing them by subject matter, and eliminating expired and amended sections. The Code is maintained by the Office of the Law Revision Counsel (LRC) of the U.S. House of Representatives. The LRC determines which statutes in the United States Statutes at Large should be codified, and which existing statutes are affected by amendments or repeals, or have simply expired by their own terms. The LRC updates the Code accordingly. Because of this codification approach, a single named statute (like the Taft–Hartley Act or the Embargo Act) may or may not appear in a single place in the Code. Often, complex legislation
