Library Services and Accessibility
The library offers a wide array of services designed for convenience and efficiency. Patrons can utilize self-charging terminals and information kiosks to manage their visits. For those returning materials outside of standard operating hours, a dedicated Bookdrop service is available.
Online Public Access Catalogue (OPAC)
The OPAC is the primary gateway for searching the library's extensive Chinese and English collections. Users can search by author, title, subject, and other criteria. While users cannot narrow their initial search to specific categories (such as audio-visual materials only), the system provides real-time status updates on whether an item is on the shelf, on loan, or reserved. If an item is on loan, the expected return date is displayed.
Beyond searching for books, the OPAC allows users to:
- Check personal borrowing records and overdue items.
- Renew or reserve materials.
- View current and upcoming library activities.
The Multimedia Information System (MMIS)
The MMIS represents the library's commitment to integrating advanced information technology. The system utilizes a three-tier structure for Audio-on-Demand (AOD) and Video-on-Demand (VOD) services:
- First Level: High-quality video-audio servers allowing synchronized user access.
- Second Level: A more economical system using servers and jukeboxes for less frequently accessed materials.
- Third Level: A conventional distribution network supporting various formats, including DVD, VCD, LD, CD, and cassette players.
To support this infrastructure, the library has installed approximately 90 Asynchronous Transfer Mode (ATM) terminals and over 400 LAN workstations. Additionally, the library digitizes document imaging materials—such as manuscripts, microfilms, maps, and reports—following copyright clearance, making them available in multimedia databases.

Advantages of the Digital Library
The transition to digital services offers several improvements over traditional library methods:
- Concurrent Access: Multiple users can access the same material simultaneously.
- Remote Access: Information can be searched from any networked workstation.
- Enhanced Research: Users can perform in-depth searches based on style, structure, or color format.
