An in-text citation usually contains the author's name (or other first element in the entry in the works cited list) and a page number.
A parenthetical citation that directly follows a quotation is placed after the closing quotation mark. No punctuation is used between the author's name (or the title) and a page number.
The author's name can appear in the text itself or before the page number in the parenthesis:
