Sometimes an author of a book, article or website will mention another person’s work by using a quotation or paraphrased idea from that source. (This may be called a secondary source.) For example, the Kirkey article you are reading includes a quotation by Smith that you would like to include in your essay.
The basic rule is that in both your Works Cited list and in-text citation you will still cite Kirkey. Smith does not appear in your Works Cited list. For the in-text citation you cite Kirkey and add the words
Examples of in-text citations:
According to a study by Smith 42% of doctors would refuse to perform legal euthanasia (qtd. in Kirkey 10).
Smith states that “even if euthanasia was legal, 42% of doctors would be against this method of assisted dying” (qtd. in Kirkey 10).
Example of Works Cited citation:
Kirkey, Susan. "Euthanasia." The Montreal Gazette, 9 Feb. 2013, p. 10. Canadian Newsstand Major Dailies.
