A Prototype for Virtual Reference System

The function of virtual reference service provides in time services without the constraints of time and space making virtual reference services an important solution for distance services. Virtual reference service, particularly the synchronize as different from asynchronous, allows patrons to interact with the reference librarian online and share and clarify information needs of which meets Taylor’s “Question Negotiation” model. The purpose of this study is to identify the major functions of virtual reference service system to allow virtual reference librarians and patrons working together online to discuss and to clarify the patron’s information need, and for the reference librarians to explain the resources to the patrons at the same time. Research methods include webpage analysis, system analysis to determine the system functions. A prototype platform for virtual reference services was developed accordingly. And a formative evaluation was applied. The formative evaluation supports the prototype functions particularly the co-browsing function for virtual reference services.
