While it's good practice to include as much information as possible in a parenthetical citation for clarity, it's not always necessary to include all three elements (name, title, page number). Here's why:
* The specific citation style dictates the required information. Different styles (MLA, APA, Chicago, etc.) have their own rules about what must be included.
* Some information may be redundant. If you've already mentioned the author and title in the text, including them again in the parenthetical citation might be unnecessary.
* Page numbers aren't always required. Some sources, like websites or videos, may not have page numbers. In such cases, you might only include the author's name (if available) or a shortened title.
Here are some examples:
MLA:
* Author in text: "Shakespeare's use of language in *Hamlet* is remarkable" (Shakespeare 120).
* Author not in text: ("The Tragedy of Hamlet, Prince of Denmark" 120).
APA:
* Author in text: Smith (2023) found that...
* Author not in text: (Smith, 2023).
Therefore, the specific requirements for a parenthetical citation depend on the chosen style guide and the context of the citation itself.
