Chicago 18 (Author-Date) Regulation Citation Generator

Citing a regulation (administrative agency rule or executive order) under the Chicago Manual of Style (Author-Date System) framework requires combining Chicago Manual of Style (author-date)'s punctuation hierarchy with the specific metadata of the source. To construct a compliant entry, researchers must collect the regulation title or subject, Code of Federal Regulations (C.F.R.) or Federal Register volume, agency abbreviation, section/page number, and year of codification. In the body of your paper, Chicago Manual of Style (author-date) utilizes parenthetical author-year citations with no comma between the author and year, e.g., (Author Year, page), which links directly to an entry organized in alphabetical by author family name and chronological by publication year.

When formatting a regulation in Chicago Manual of Style (author-date), pay close attention to contributor names and capitalization. Specifically, Chicago Manual of Style (author-date) enforces inverting only the first author name (Last, First) while writing subsequent co-authors in normal order (First Last) connected by the word "and", and applies headline-style Title Case for all titles, placing analytical works in quotation marks and standalone containers in italics. Chicago Author-Date places the year immediately after the author without parentheses in the reference list, and spells out first names rather than reducing them to initials. Furthermore, if your regulation does not display an individual creator, the rule is straightforward: begin with the regulation title or CFR citation; credit the issuing government agency in the authority or publisher slot if required by your style.

For digital and online regulation references, Chicago Manual of Style (author-date) stipulates placing the DOI (https://doi.org/...) or stable URL at the very end of the entry, requiring an access date only when no publication date exists. Note whether the regulation is already codified in the C.F.R. or is still a proposed/uncodified rule published in the Federal Register.
