Please visit the links on this page before looking at citation for specific types of sources.
Formatting footnotes/endnotes and bibliographies discusses the format of sample citations on the Turabian pages. Subsequent notes involve consecutive citations from a single source. An exception to the footnote rule clarifies the use of multiple sources within a single paragraph, but check with your professor before using this exception.
To see an example of a secondhand or indirect source, visit Turabian Book Sources and scroll to 'One Source Quoted in Another.'
