Primary sources are preferred in most academic work, but if the primary source is unable to be located or otherwise unavailable, follow the steps below.

"Follow these directions when citing a secondary source:

• In the reference list, provide an entry for the secondary source that you used.
• In the text, identify the primary source and write “as cited in” the secondary source that you used."
