A: The best way to do this, regardless of citation style, is to work in the reference to the original source within the context of your paper.
Here is how you would do this in MLA 8 style:
In the text, name the original author and give a citation for the source where you read it.
Example: According to Charles Dickens (as cited in Brown 33)…..
Then, list the source you read in your reference list.
Brown, Frank. Life Lessons in the Works of Charles Dickens. Scholastic, 2011.
