About Chicago 17th

The Chicago Manual of Style allows for two different types of reference styles. There is the Notes and Bibliography Style (the subject of this guide), and the Author-Date System (a variation of the Harvard style).

While the Notes & Bibliography Style allows for either footnotes or endnotes, this guide will deal with footnotes. Bibliographic citations are provided in footnotes, supplemented by a bibliography at the end of the document. Your footnotes and bibliography should identify references cited (eg. book, journal article, webpage, video) in sufficient detail so that others may locate and consult your references. Each note corresponds to a raised (superscript) number in the text.

Punctuation marks and spaces within the citation are very important. Follow the punctuation and spacing as given in the examples.

A note may look like this:

1. Alastair Blanshard, Hercules: A Heroic Life (London: Granta, 2006), 151.

While a bibliographic entry may look like this:

Blanshard, Alastair. Hercules: A Heroic Life. London: Granta, 2006.

Any subsequent lines in a reference are on a hanging indent.  A hanging indent is an indent that indents all text except the first line.
