This document discusses different library management systems including indigenous, barcode, and RFID systems. The indigenous system uses Excel to manage tasks like member registration, book purchasing, and inventory. The barcode system uses barcodes on books and member cards to automate circulation. RFID uses radio frequency technology to track library assets and automate check-in, search, check-out, and return of materials without human intervention. Both barcode and RFID systems provide benefits like faster transactions and improved security but also have some limitations.
