Determine if the sentence needs a citation. If you use a direct quotation from a source, it needs a citation. Additionally, if you paraphrase another person's idea, it needs a citation.
Refer to the bibliography for pertinent information, including the author's name. The style of the bibliography varies depending on the assignment, including Chicago style and Turabian style.
Embed the source in the text. Because the bibliography contains the full information on the source, when you cite it in the main text, it is only necessary to provide a reference. Thus, you can say, "According to Dr. Miller..." at the end of the citation, then provide a parenthetical reference to the page number of the source.
Create a footnote. Depending on the style of the paper, a footnote may be used either as a supplement to the embedded reference or in lieu of it. Again, the footnote should include the author's name and page number. Do not use parenthesis.
