Where does the close quote (“) go with a in-text citation?
“Did that really happen?…No, but it could have (p. 10).”
“Did that really happen?…No, but it could have” (p. 10).
In MLA, APA, CMS, and I don’t know how many other citational styles, the invariable rule is to put the close quotation marks before the parenthetical citation, but hold off on the sentence-ending period till after the parenthetical citation. (This last bit was not asked about, but if I had a nickel for every period I have had to mark for relocation thus in a student paper, I would be rich.)
