Secondary sources

A secondary source is a work that you have only read about, and have not read the original document. For example, a study may be summarised in a journal article you are reading. The study itself is a primary source, whilst the journal article referring to it is the secondary source.

To refer to a secondary source, list the primary and secondary sources in the text, but only fully reference the secondary source you have actually read in your references page.
