Q. How do you author-date cite multiple quotations by the author in one paragraph?
A. If it’s clear from the context that the quotations are all from the same source, you can combine the page citations at the end of the paragraph, in the order they appear (Charles 1991, 47, 212, 21). If the source is clear but the quotations are many and scattered, after the first author-date citation (Charles 1991, 47) you may put simple page citations at the end of each quote thereafter (212).
