Regulations created by administrative agencies are primary materials such as statutes and cases.
Rules and regulations of federal agencies are first published in the Federal Register, which comes out each business day, except federal holidays.
Regulations are eventually published in the Code of Federal Regulations (CFR), which is a subject compilation of the rules and regulations in effect at the time of its publication. This guide offers more information about the Federal Register and the CFR and how to locate them.
Regulations.gov, while not an official source of administrative rules, provides an online portal for access to agency rulemaking documents, including proposed rules and public comments submitted in regard to proposed rules.
The Law Librarians' Society of Washington D.C. has an excellent Research Guide to the Federal Register and the Code of Federal Regulations. This guide provides information on the historical development of the Federal Register and CFR, guidance on the contents and organization of the Federal Register and CFR, and insight on finding tools to utilize with the Federal Register and CFR.
