Core Elements of a Citation
The entries in a Works Cited page, according to the MLA, are made up of "core elements." In order, these are:
Author: The work's primary creator(s).
Title of Source: The work's title.
Title of Container: The location containing the work, i.e. a website, database, or periodical.
Contributor: A key contributor to the work besides the primary author(s).
Version: Included if the work has been produced in more than one form, i.e. a second edition.
Number: Included if the work is part of a sequence, i.e. a numbered volume or issue.
Publisher: The entity responsible for distributing the work, i.e. a publishing house.
Publication Date: The date when the work was published.
Location: Included mainly for the URLs of online sources and page ranges of works contained in other works (Modern Language Association of America 105).
If any of the above is missing from the work, it should be skipped in the citation. The rules for prose apply to these entries for capitalization and styling (i.e. italics).
