Chapter 2

In Chapter 1 of this short reader on adding Chicago footnotes, we looked at three combinations of reference feature in the Chicago style: citations, endnotes or footnotes and bibliographies. We discussed how sources are cited in Chicago using these features and we explored how to determine which source information should and shouldn’t be cited. In this final chapter on the subject, we next focus specifically on building, arranging, formatting and displaying notes in this style of referencing, offering examples to help guide students through the process.


Are footnotes similar to bibliography references?

As was briefly demonstrated in Chapter 1, footnotes (or endnotes) and bibliography references are very similar in the Chicago style:

Both footnotes and bibliography references offer comprehensive information about the source being cited and are placed outside of the main text – unlike citations.

Why are reference elements important?

Footnotes and references are also both constructed by a writer through the gathering of source details across a number of key reference elements. These elements change depending on the source type being cited. While a conference proceeding might have six elements for example, a book may have four – or a journal article might have six different elements (see our reader on referencing sources in Chicago to see the patterns for each source type). This is exemplified in the two figures below. On the left we have the six necessary reference elements for these source types and next to those elements the source details:

How should Chicago footnotes be formatted?

It’s important once students have collected the details of their source that they know how to correctly format those details. This means paying careful attention to rules of capitalisation, punctuation, spacing and italicisation. Some general rules for formatting Chicago-style footnotes are provided for you below:

  • end footnotes with a full stop (.)
  • italicise book, journal and website titles
  • indent the first line of a footnote by 1.3cm
  • use commas to separate reference elements
  • place the authors’ forenames before their surnames
  • use double quotation marks (“”) for article and chapter titles
  • capitalise the first letter of a title only (as well as any proper nouns)

Many of these rules can be seen in the formatted source details for conference proceedings and journal articles below:

Can ‘et al. and ‘Ibid.’ be used?

To help speed up the referencing process somewhat, there are two helpful Latin expressions which can be used in the Chicago style, ‘et al.’ and ‘Ibid.’:


  1. write ‘Ibid.’ (meaning the same) in the footnote instead of the formatted source details if two or more consecutive footnotes are referencing the same source
  2. write ‘et al.’ (meaning and others) in the footnote instead of the authors’ names when there are four or more authors to the source being reference
