When using in-text citation how do you note two books by different authors?

When citing two books by different authors in the same in-text citation, you list them alphabetically by the first author's last name, separated by a semicolon.

For example, using MLA style:

(Author A's last name Year; Author B's last name Year)

Example:

The impact of climate change is widely debated (Smith 2022; Jones 2023).

Important Note: The specific format (e.g., using parentheses, semicolons) will depend on the citation style you are using (MLA, APA, Chicago, etc.). Always consult the style guide's specific instructions.
