When you write a paper, the MLA Handbook for Writers of Research Papers says: "You must indicate to your readers not only what works you used in writing the paper but also what you derived from each source and where in the work you found the material" (214). Therefore, the citation is that documentation.
For example, I should cite the above work as indicated below, using New Times Roman, 12 pt.
