Which statement accurately reflects the three codal sets used to locate federal statutes?

• A. There are three sets: U.S.C., U.S.C.A., and U.S.C.S
• B. There are two sets: U.S.C. and U.S.C.A.
• C. There are four sets including Congress.gov
• D. There is only U.S.C.

Answer: (A)

When researchers locate federal statutes, they rely on three codal sets that organize the statutory text and provide authoritative navigation. The official United States Code presents the statutes in title-and-section format. To aid interpretation and research, two widely used annotated versions accompany the text: United States Code Annotated (U.S.C.A.), which adds extensive case law citations, editorial notes, and cross-references, and United States Code Service (U.S.C.S.), which offers similar annotations and regular updates. These annotations are invaluable for understanding how statutes have been interpreted, amended, and connected to other authorities. Online resources like Congress.gov can provide access to the statutes and legislative history, but they are not codal sets themselves. They complement the codal material rather than replace the three traditional codal sets.
