Here's a breakdown:
Yes, full name is used in these styles:
* MLA: Use the author's full name in the order it appears on the source (e.g., "Smith, John").
* Chicago: Use the author's full name in the order it appears on the source (e.g., "Smith, John").
* APA: Use the author's full name, but use initials for middle names (e.g., "Smith, J. ").
No, full name is not used in these styles:
* Harvard: Use the author's last name and first initial (e.g., "Smith, J.").
Other considerations:
* If the author has a long name: Some styles might allow you to shorten the name for the sake of brevity, especially if it's repeated many times.
* If the author has a title: You might need to include the author's title in the reference entry depending on the style.
* If the source has multiple authors: The order and formatting of authors will vary depending on the style.
Always consult the specific style guide you are using for the most accurate information about how to format reference page entries.
