Let’s say the article you are reading by one author (Author A) quotes an article by another author (Author B). The quotation from Author B is what you want to include in your paper, but you found it in Author A’s article. How do you cite it?
Look at the category the information falls under:
- The original work is available: Read the original source (Author B) and cite that as you normally would.
- The original work is unavailable, out of print, or in another language: Cite the secondary source (by Author A) in the reference list and in-text citation, and include the name of the original work (by Author B) in the text, e.g. Smith’s thesis (as cited in Donaldson, 2006).
