• Use secondary sources sparingly
• Always try to locate the original source of information which is cited in a work that you have read.
This is not always possible. For example, when the original work is:
• Reference may be made to an author's citation of, or quotation from, another's work.
• Distinguish between works cited and quoted.
• Both the original and secondary source should be listed in your footnote.
• A corresponding entry should also be listed in your bibliography.
