Nonfiction Reference History Books are a category of literature that provides factual information about historical events, figures, or periods. These books, rooted in reality and not imaginative creation, serve as a tool or a guide, aiding readers in gaining knowledge about the past. They differ from non-fiction drama books, which are based on real-life events but dramatized for the purpose of storytelling. History books, in general, may include both fiction and non-fiction, but this category specifically focuses on non-fictional accounts. They form a subset of the broader category of non-fiction books and non-fiction reference books, emphasizing real-life historical narratives.
