A reference book is a type of publication that provides factual information and is designed to be consulted for specific data rather than read from cover to cover. Common examples include dictionaries, encyclopedias, and atlases. These books are often organized in a way that makes it easy to find information quickly, such as alphabetical order or by subject. Reference books are typically used in libraries, schools, and homes for research or study purposes. They serve as reliable sources for students, professionals, and anyone seeking accurate information on a wide range of topics, including history, science, and geography.
