Aug 1, 2025

Overview

This guide explains how to properly cite Federal Regulations using sources like the Federal Register and the Code of Federal Regulations (CFR), including specific formats and APA style guidelines.

Sources of Federal Regulations

  • Federal Regulations are published in the Federal Register and the Code of Federal Regulations (CFR).
  • The Federal Register is a daily publication containing new and proposed regulations.
  • The CFR organizes regulations by subject and is the preferred source for citations.

Citing the Federal Register

  • Include the volume number, page number, and date of publication in the citation.
  • Example: 87 Fed. R. 12345 (January 1, 2022).

Citing the Code of Federal Regulations (CFR)

  • Cite using the title number, part or section number, and the year of the regulation.
  • Example: 29 CFR 1980.103 (2022).
  • The title number refers to the broad subject area (e.g., 29 = labor).
  • Use "pt" for citing a whole part: 29 CFR pt. 1980 (2022).
  • The CFR is updated quarterly: Titles 1โ€“16 (Jan 1), 17โ€“27 (Apr 1), 28โ€“41 (Jul 1), 42โ€“50 (Oct 1).

APA Style Citation

  • APA format requires the title of the regulation (capitalized), CFR citation, section number, and year.
  • Example: Protection of Human Subjects, 45 C.F.R. ยง 46.109 (2009).
  • In-text citation format: (Protection of Human Subjects, 2009).

Key Points to Remember

  • Always cite the most recent CFR edition.
  • Include the title number, part or section number, and the regulation year.
  • For APA style, capitalize the regulation title and include the section number and year.
