Chicago 18 (Author-Date) Standard Citation Generator

Citing a standard (technical, industrial, or engineering specification) 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 standards organization (e.g., ISO, IEEE, ASTM, NIST), publication year, official standard title, standard alphanumeric code/number, and publisher or URL. 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 standard 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 standard does not display an individual creator, the rule is straightforward: always use the issuing standards body (such as International Organization for Standardization [ISO]) as the corporate author.

For digital and online standard 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. Place the standard number in parentheses immediately after the title (APA) or at the start of the entry (IEEE) as dictated by your style manual.
