Documentation (doc)

Unless you are asked or permitted to do otherwise, use the MLA method of documentation, which requires parenthetical references keyed to a list of “Works Cited,” rather than footnotes or endnotes. See the MLA Handbook (Chapters 4 and 5) and Sections III and IV above.
In your first non-parenthetical reference to a source give both first and last name; thereafter, use the last name only.
