MLA Style: Online sources: Parenthetical References
Note: These examples follow the format described in the MLA Handbook for Writers of Research Papers (7th edition).
In addition to producing a "list of works cited" for your paper, you must provide details about the information you derived from each of your sources and where in the source you located this information. The best way to do this is to insert a brief parenthetical acknowledgement whenever you use another person's ideas or words. This allows the reader to refer to the "list of works cited" for complete information on the source.
With online sources there are no traditional "pages" to reference (as there are with print sources) when providing the necessary detail about information you derived from each source. However, there may be other reference markers you may use, such as numered paragraphs, sections, or screens.
Sources with reference markers
If the source has numbered paragraphs, sections, or screens, use "par." (or "pars."), "sec." (or "secs."), or "screen" (or "screens").
