Federal Regulation research is divided into two separate areas: (1) administrative law, which deals with the validity and creation of agency created law; and (2) the research of the agency law itself. This series of research guides deals with the latter.
The Code of Federal Regulations (CFR) is the codification of federal regulations.
The Federal Register (FR) is a daily publication that contains the federal regulations (final rules) and is used to find new regulations and amendments to current regulations since the last codification (update) of the Code of Federal Regulations.
