Chicago Style

About Chicago Style

There are two parts to referencing: the citations within the text of your paper and the reference list at the end of your paper.

Chicago style  is an "author-date" style, so the citation in the text consists of the author(s) name and year of publication given wholly or partly in round brackets.

Use only the surname of the author(s) and the year of publication. Include page, chapter or section numbers, preceded by a comma, if you need to be specific:

When citing in the text, no distinction is made between books, journal articles, internet documents or other formats, except for electronic documents that do not provide page numbers. In this case, use the paragraph number, if available, with the abbreviation para.

The full details of the source are given in a reference list at the end of the document:

Reference list entries contain all the information that someone needs to follow up your source. Reference lists in Chicago are arranged alphabetically by the primary author's surname.

Reference list entries vary depending upon the format of the source of your information. See Reference List Entries or All Examples for details on how to construct references for specific resources such as books, journals and web pages.
