In MLA Style, referring to the works of others in your text is done using parenthetical citations.
his method involves providing relevant source information in parentheses whenever a sentence uses a quotation or paraphrase. Usually, the simplest way to do this is to put all of the source information in parentheses at the end of the sentence (i.e., just before the period).
IN-TEXT CITATIONS: AUTHOR-PAGE STYLE
MLA format follows the author-page method of in-text citation. This means that the author's last name and the page number(s) from which the quotation or paraphrase is taken must appear in the text, and a complete reference should appear on your Works Cited page. The author's name may appear either in the sentence itself or in parentheses following the quotation or paraphrase, but the page number(s) should always appear in the parentheses, not in the text of your sentence. For example:
Wordsworth stated that Romantic poetry was marked by a "spontaneous overflow of powerful feelings" (263).
Romantic poetry is characterized by the "spontaneous overflow of powerful feelings" (Wordsworth 263).
Wordsworth extensively explored the role of emotion in the creative process (263).
