In literature, "ii" is commonly used as a shorthand to designate the second part or volume of a work, serving as a clear, concise reference to a specific segment within larger texts. For instance, Roman numeral "II" identifies distinct subdivisions like chapters or volumes in historical and classical works—such as in Strabo’s Geography ([1], [2]) and Bishop Augustine’s The City of God ([3], [4])—and even in dramatic texts like Shakespeare’s plays ([5], [6]). This usage not only aids in systematic organization and citation but also allows scholars and readers to quickly navigate extensive narratives or scholarly discussions across various genres and time periods.
