A genre of books and writings that offers factual, real-world information and narratives, often covering historical events, biographical accounts, and various other aspects of reality. This category includes a wide range of literary works such as literature history, which explores the development and evolution of written works throughout different periods and cultures, and short stories, which are brief, standalone works designed to convey a single theme or idea. In the broader context, it also encompasses all forms of literature that are based on factual, rather than fictional, content.
