What term refers to books that provide factual information and are often categorized as nonfiction?

The term that refers to books providing factual information and categorized as nonfiction is "Informational Text." This type of text is specifically designed to inform readers about factual content, ranging from science and history to technical subjects. Informational texts are characterized by their use of data, illustrations, graphs, and other elements that support and enhance the conveying of factual information.

In educational settings, these texts are vital for developing students' comprehension skills, as they often require readers to interpret actual data or processes rather than engage with narrative storytelling. The clarity and logic in presenting facts and concepts help students learn to differentiate between various types of information and understand how to analyze real-world phenomena.

The other options represent different categories of texts but do not align with the definition of providing factual information as clearly as informational text does. Literary texts, for example, are created primarily for artistic expression and often involve fictional narratives, while textual analysis pertains more to the study of written material rather than a genre of text.
