Which term denotes a collection of quantitative measures of library use and demand?

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

Answer: (A)

Usage statistics collect and summarize the numbers that show how the library is used and what patrons need. It includes a range of indicators—circulation counts, visits, database usage, reference interactions, interlibrary loan requests—providing a complete picture of use and demand. This breadth is what makes it the best fit for describing a collection of quantitative measures across library services. The other terms refer to more specific aspects: circulation patterns look at borrowing behavior, database usage focuses on one resource type, and computer lab utilization is about a single facility. In practice, librarians use usage statistics to monitor trends, plan services, and allocate resources.
