Common Citation Examples: 

In-Direct Sources:

Because authors are generally expected to be intimately familiar with the sources they are citing, Chicago discourages the use of a source that was cited within another (secondary) source. In the case that an original source is utterly unavailable, however, Chicago recommends the use of "quoted in" for the note:


7. Ian Hacking, The Social Construction of What? (Cambridge, MA: Harvard University Press, 1999), 103, quoted in Manuel DeLanda, A New Philosophy of Society (New York: Continuum, 2006), 2.
