The United States Code (USC) is a topical arrangement of all the federal statutes of the United States. When a bill becomes law, it is first published as a slip law and in the annual Statutes at Large. It is then divided into parts (if necessary) and codified under the appropriate titles of the USC, to make it easier to locate. A single law may end up in several different sections of the USC (sometimes even different parts, chapters, or titles), depending on the topical contents of the various pieces of the law.
There are several ways to look at the USC. The Office of the Law Revision Counsel published an official print set that contains nothing but the statutes themselves.
Additionally, both Thomson West and LexisNexis publish annotated versions of the USC that contain proprietary additions to the statutes, such as headnotes and Key Numbers. The Thomson West version is called United States Code Annotated, and the LexisNexis version is called United States Code Service. Both versions are available electronically, through WestlawNext and Lexis Advance, respectively.
One key difference between these two versions of the US Code is the source of the language itself. USCS uses the language provided in the Statutes at Large, whereas USCA uses the language from the official US Code. Typically, these should be the same, but on rare occasions it is discovered that slight changes occurred during the codification process. Generally, when the language is inconsistent, courts have held that the language in the Statutes at Large is controlling.
There are additional differences, as well:
U.S.C.A. seeks to be comprehensive in its case annotations, including every relevant case that discusses the statute, while U.S.C.S. includes only selected cases in its annotations.
While both sets include references to related administrative regulations, only U.S.C.S. includes references to cases decided by administrative law courts (U.S.C.A. does not).
While both sets include references to law journal articles, ALR annotations, and AmJur articles, there are differences in the coverage of secondary source materials in the annotations.Since U.S.C.A. is published by West publishing, you will find references to print treatises published by West publishing, but not to those published by Lexis publishing.Additionally, C.J.S. is included only in U.S.C.A.Likewise, since U.S.C.S. is published by Lexis, it will contain references to print treatises published by Lexis but not those published by West.
Since it is published by West, U.S.C.A. has references to the West Topic and Key Number system, while U.S.C.S. does not.

Both USCA and USCS use annual pocket parts to update each volume, and both occasionally publish softbound volumes during the year to update the pocket parts. The official US Code is updated with a bound supplement each year.
USCA: Within the pocket parts, use the table called "U.S. Code Sections Amended, Repealed, New, Etc." The table will provide a citation to the public law number that affected each changed section of the Code, and you can look up that law to see how the section was affected.
USCS: Each Advance pamphlet contains a table called "Table of Code Sections Added, Amended, Repealed, or Otherwise Affected," which can be used to check whether a particular section has been changed. These pamphlets are compiled annually in the Cumulative Later Case and Statutory Service.
You should always ensure you check online sources, as well, since print materials are typically slower to update than digital sources. If you don’t have access to WestlawNext or Lexis Advance, you can look at Congress.gov.
Each of the 50 titles in the USC contains law on a particular topic. Note that there is no Title 34, which dealt with the United States Navy prior to 1956. Additionally, Title 6 used to deal with surety bonds. Those provisions were repealed or moved to Title 31 in 1972 and 1982, and the new Title 6 was first introduced in the Homeland Security Act of 2002.
