Which term describes data on how often library materials are borrowed?

• A. Circulation patterns
• B. Usage statistics
• C. Database usage
• D. Computer lab utilization

Answer: (A)

Borrowing activity over time is what this term describes. Circulation patterns refer to data about how often library materials are borrowed, including how frequently items circulate, which items are most popular, and how borrowing changes across days, weeks, or seasons. This framing captures not just counts but the behavior and trends in lending, which librarians use to plan collections and services. Other terms describe broader or different kinds of usage: usage statistics can cover a wide range of resources and services, database usage focuses on online databases, and computer lab utilization measures use of computer workspaces rather than loans. So, the term that best fits data on how often materials are borrowed is circulation patterns.
