What is the difference between a reference book and a circulating book?

Excuse me, could you please elaborate on the distinction between a reference book and a circulating book? I'm curious to understand how these two types of books differ in terms of their intended use, availability, and the way they are organized or catalogued in a library setting. Additionally, are there any specific examples of each that you could share to help me better grasp the concept? Thank you for your time and expertise.
