Q. If I am making a direct quotation and using the author-date references, the reference is supposed to go within the sentence before the period. But what if the quotation is at the end of the sentence? Do I use two periods? E.g.: Carrington, a Thatcherite conservative, remarked after the Lancaster House agreement in 1979 that “if any man left Lancaster House transformed in the eyes of Western statesmen, it was Mugabe.” (Chan 2003, 14).
A. The rule stays the same—keep the citation within the sentence, before the period: Carrington, a Thatcherite conservative, remarked after the Lancaster House agreement in 1979 that “if any man left Lancaster House transformed in the eyes of Western statesmen, it was Mugabe” (Chan 2003, 14). The presence of a question mark or exclamation mark at the end of the quotation doesn’t change the need for a period after the citation: Did Carrington say that “it was Mugabe”? (Chan 2003, 14).
