How to Cite Secondary Sources in Chicago Style

In our citation examples we use the following color coding:

  • Red – Author
  • Blue – Title of book/article/charter/webpage
  • Pink – Date
  • Orange – Website/Publisher
  • Turquoise – Place of publication
  • Sienna – Pages


Mind that the 16th edition of Chicago Manual of Style discourages the use of secondary sources in academic research.

It is to be avoided at all times. In case the original source is not available, it is better to use the “quoted in” format for the footnote.

No bibliographical citation is necessary.


Footnote citation: 1. Jim Bean, A Book about Nothing, (New York, NY: Elsevier, 2001), 37, quoted in Alexander Schultz, Modern Nihilism (London: Routledge, 2007), 5.
