The MLA Handbook provides a "universal set of guidelines" for citing sources across all format types. Luckily, the 9th edition mainly expands upon the rules listed in the 8th edition. There are no significant changes in Works Cited/In-Text Citations (whew!).
These guidelines state that, if given, these major elements should be included in the citation:
1. Author.
2. Title of Source.
3. Title of Container,
4. Other Contributors,
5. Version,
6. Number,
7. Publisher,
8. Publication date,
9. Location.
