Here is an excerpt from the UNC Writing Center:

GIVING ADDED EMPHASIS TO A PARTICULARLY AUTHORITATIVE SOURCE ON YOUR TOPIC.

There will be times when you want to highlight the words of a particularly important and authoritative source on your topic. For example, suppose you were writing an essay about the differences between the lives of male and female slaves in the U.S. South. One of your most provocative sources is a narrative written by a former slave, Harriet Jacobs. It would then be appropriate to quote some of Jacobs’s words:

Harriet Jacobs, a former slave from North Carolina, published an autobiographical slave narrative in 1861. She exposed the hardships of both male and female slaves but ultimately concluded that “slavery is terrible for men; but it is far more terrible for women.”

In this particular example, Jacobs is providing a crucial first-hand perspective on slavery. Thus, her words deserve more exposure than a paraphrase could provide.

Jacobs is quoted in Harriet A. Jacobs, Incidents in the Life of a Slave Girl, ed. Jean Fagan Yellin (Cambridge: Harvard University Press, 1987).
