NOTE: Works cited entries for works with no author are alphabetized by title. Ignore initial articles (a, an, the). If the title is longer than a few words, abbreviate it in the parenthetical reference, as shown above. For ease of reference, ensure that your abbreviated title begins with the same word as the full title.
For works with no page numbers, such as video recordings, it is preferable to include the author's name, or, in the case of a source with no author, the title, in the text and omit a parenthetical reference altogether.
If it is relevant, include the original release date between the director and distributor, followed by a period (see the first example above).
