For quotations in the main body of the text, follow CMS16, 13.66.
Example: According to Hunter, "Handel is much better than Bach" (p. 23).
Also: How could Hunter possibly claim that "Handel is much better than Bach" (p. 23)?
For block quotations, follow CMS16, 13.68. Note that page reference follows the final punctuation of the quotation:
Despite the writings of other scholars, Hunter stands firm:Handel is much better than Bach. His vocal writing shows a masterful knowledge of the voice and its capabilities. The instrumental character of Bach's vocal parts makes them difficult for all but the most talented singers to perform. (p. 123)
Use p. 22ff. (not "pp. 22ff."). "Only when referring to a section for which no final number can usefully be given should ff. . . . be resorted to. Instead of f., the subsequent number should be used (e.g., "140-41" not "140f."(CMS16, 14.156)
