Here's why:
* Reference materials are designed for quick look-up and information gathering, rather than extended reading.
* They typically cover a wide range of subjects, providing concise and factual information.
* They are usually kept in a designated area of the library, often near the front entrance, for easy access.
* Reference books are not typically checked out, but are used within the library.
