Punctuation

Q. In this example {The stationery is described in John R. MacArthur’s book The Selling of “Free Trade,” p. 217}, is it right for the quotes that apply only to “Free Trade” to fall after the comma? And if so, should the comma revert to roman but the quotes remain in italics?

A. Commas always go inside the quotation marks. Punctuation is formatted to match the surrounding text, so a comma that falls within an italic title should also be italic.
