Each parenthetical citation includes the author’s last name, date of publication, and sometimes a page number, and is keyed to a corresponding citation in a complete list of references, where full bibliographic information is provided. Sources are briefly cited in the text and enclosed within parentheses. The Chicago style citation also has an author-date variant, which is commonly used by those in the physical, natural, and social sciences. Full details of the source information can be located in the bibliography, which is presented at the end of the essay in alphabetical order by author. A superscript number at the end of the sentence signals to the reader that a source has been used, and summary details of the source can be found using the numbered footnote at the bottom of the page. The notes and bibliography system is primarily used in the humanities – including literature, history, and the arts – because it is a flexible style that accommodates unusual source types and opens up space for commentary on the sources cited. So read on to see how both Chicago variants work. This guide is not officially associated with the citation style, but it will give you a good overview of the rules and format.
