What is a "reference book" intended for?

A reference book is specifically designed to provide quick access to specific information. These types of books, such as encyclopedias, dictionaries, and atlases, are organized in a way that allows readers to look up facts, data, and definitions without needing to read the entire text. They serve as reliable resources for detailed or factual information on a wide range of topics, making them valuable tools for research, study, and everyday inquiries.

While some books may be intended to be read completely, reference books prioritize usability and efficiency, allowing users to find the information they need quickly. Unlike narrative books, which focus on storytelling, or personal diaries, which are meant for individual reflection, reference books are used primarily for informational purposes.
