The Chicago manual of style sets out two referencing systems: footnotes and a bibliography, and an author-date system similar to APA.
The footnoting and bibliography style is summarised in brief below. For further information on Chicago footnoting, or Chicago's author-date style, consult the Chicago manual of style 17th edition or The Chicago manual of style online website: http://www.chicagomanualofstyle.org/tools_citationguide.html
In the footnote-bibliography system, authors are identified by a number in the text, and further details indexed by number at the bottom of the page in the form of footnotes, or at the end of the text in the form of endnotes.
The first time a source is used the note contains all pertinent information about the source (title, publishers, etc.). If the same source is used again, a shortened version is given.
The shortened version (footnote 2 in the example below) contains only the author's surname, the title (which can be shortened if it is longer than four words) and the page number.
The full version (footnote 1 in the example below) contains more detailed information, depending on the type of source.
All sources mentioned in notes must also be included in the bibliography at the end of the document. The format of each entry is similar to the full version of the note, with a few minor changes:
- The first author's surname is put before their first name (so "Mason Durie" becomes "Durie, Mason")
- Commas between the author, chapter/article title, and book title are replaced with full stops
- Brackets are removed from around publication information. They are kept for the year of publication of a journal article, however
- Page numbers for books are removed, or (in the case of journal articles) replaced with the full page range
The entries each have a hanging indent, and are alphabetised according to the surname of the first author.
Order: Author, Book Title, edition. (City of publication: publisher name, year), page number
Cottrell1 emphasises the use of outside source materials in academic writing. When writing an assignment, this will form the crucial second step.2
