Chicago Referencing Guide
Chicago referencing has two different styles: a footnotes style, which is usually used in humanities disciplines, and an in-text citation style, which is most commonly used in the sciences.
Chicago Referencing Overview
Key things to remember
There are two types of Chicago referencing. One style uses footnotes, which are marked in text with a number by the citation and detailed in full at the bottom of the page, and bibliographies, which should include all works directly cited in the piece as well as any sources which have been examined in relation to the subject. This is very similar to Oxford referencing. The other uses in-text citations which are listed in a reference list at the end of the work (like Harvard referencing). Examples of how to render both styles will be given in this guide.
Footnotes should be displayed in text like this:
'Lille and Cranmer1 purport that this is the best option for modern restaurant-goers.'
The full citation that would be found at the bottom of the page would then be presented like so:
1 Jennifer Lille and Elsa Cranmer, Savvy: A Restaurant Guide. (Nottingham: Delectable Publications, 2005), 25.
Subsequent citations of the same source in the footnotes can be condensed – e.g.:
1 Lille and Cranmer, Savvy, 27.
A full citation for this source would also be found in the bibliography: the only difference is that in the bibliography, the author's surname is listed first. These should be displayed alphabetically by author's surname.
In-text citations should be presented like so: (Jones and Hughes, 2004, 9).
1. Books
Citations for books with one author:
Footnote style
Last name, first name. Title. Edition (if not the first edition of the book). (City of publication: Publisher, Year).
In-text style
Last name, first name. Year. Title. Edition (if not the first edition of the book). City of publication: Publisher.
For example:
Footnote style
Davis, Bryan. A History of Chocolate. (Nottingham: Delectable Publications, 2011).
In-text style

Citations for books with two or three authors:
Footnote style

Citations for books with four or more authors:
If a book has four or more authors, only the first author's name should be listed in-text followed by 'et al.'. In the reference list/bibliography, you should list all authors. This is the same in both Chicago styles.
Footnote style
Last name, first name, Last name, first name, Last name, first name, and Last name, first name. Title. (City of publication: Publisher, Year).
In-text style
Last name, first name, Last name, first name and Last name, first name. Year. Title. Edition (if not the first edition of the book). City of publication: Publisher.

Citations for a chapter in an edited book:
When citing a single chapter in a larger book, it is important to ensure that you add the page range (pp.) that the chapter spans.
Footnote style
Last name, first name. 'Chapter name' in Book title, ed. by Editor/s name/s. (City of publication: Publisher, Year). Page/s.
In-text style
Last name, first name. Year. 'Chapter name'. In: Book Title. Edited by: Editor/s name/s. Edition (if not the first edition of the book). City of publication: Publisher.

Citations for multiple books by the same author:
In text, the author's texts can usually be differentiated by year. They should be listed in chronological order of publication. Where you are citing two works by the same author which were published in the same year, these should be labelled with 'a', 'b', 'c' and so on directly after the year.
