Referencing style - Chicago: Citations Taken From Secondary Sources

A guide to using the Chicago citation referencing style for footnotes and reference lists.

Citations Taken From Secondary Sources

Citing a secondary source is generally discouraged, since authors are expected to have examined the works they cite.

If an original source is unavailable both the original and the secondary source, record the secondary source as part of the narrative, and record 'quoted' in the in-text citation. Only the original should appear in the bibliography.
