When you quote, paraphrase, summarize, or refer to another source, you should include an in-text citation. For each in-text citation, you should also include an entry on your reference list.
An in-text citation should include the last name(s) of the author(s) and the year of publication.
Examples:
A reference list should be provided at the end of your paper. The references provide the reader with the ability to locate any of the sources you cited in your paper.
References should be listed in alphabetical order, and should contain several elements, including author name(s), title of the work, publication date, and other information, depending on the type of source.
