Choose a formatting style. Ask the professor or publisher for the preferred format. Decide between using footnotes or parenthetical citations in text. Refer to the citation format to decide which style of textual citation suits your paper.
Mark each reference to a source in the text of your paper. Clearly identify passages and data that you reproduce in your text as quotations. Provide enough information, such as author's name and year of publication, in the text for the reader to find the citation in your reference list. Cite ideas or concepts that you paraphrased closely from another author, even if you did not quote directly.
Provide a works cited or references page at the end of your paper. Include all bibliographic information required by the citation format. List author's name, publication title, city of publication, publisher and date of publication. Format the information in the order that the citation format requires.
