Which term indicates a machine-readable identifier affixed to library materials for checkout and inventory control?

• A. Barcode
• B. Destiny
• C. Circulation
• D. Genrefication

Answer: (A)

Barcodes are machine-readable identifiers affixed to library materials for checkout and inventory control. A barcode encodes a unique item number, which a scanner reads to pull up the corresponding record in the library system. This lets staff quickly process loans, returns, holds, and inventory checks, while automatically updating due dates and other details in the catalog. The other terms relate to broader concepts: Destiny is a library management system that stores and manages records, circulation refers to the lending process itself, and genrefication is a method of organizing shelves by genre. None of these are the physical, machine-readable label used to identify items during checkout and inventory.
