See this example properly formatted in the QUT Cite tool.
Add quotation marks around the copied words. Any quotation over three words needs quotation marks.
In 2005, Harris wrote "you must cite the sources of each idea or item of information you use, whether you quote, paraphrase or summarise or merely refer to it" (p. 5).
If the quotation includes another quotation made in the original, use the opposite type of quotation marks (i.e. '…') to those ("…") that you used first.
You can use your own judgement on what constitutes a short quote. As a general rule, APA suggests fewer than 40 words and Harvard suggests fewer than 100 words.
