Chicago 18 (Author-Date) Encyclopedia Entry Citation Generator

Citing a encyclopedia entry (compendium reference article) 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 entry author (if signed), publication/revision year, entry title, encyclopedia editor(s), encyclopedia title, edition/volume, 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 encyclopedia entry 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 encyclopedia entry does not display an individual creator, the rule is straightforward: for unsigned entries in general encyclopedias, place the entry title in the author position or credit the corporate editorial board.

For digital and online encyclopedia entry 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. For scholarly online encyclopedias that archive editions (like SEP), always cite the specific archive edition season and year (e.g., Spring 2025 ed.).
