The resource-oriented digital library, the system-oriented digital library and the service-oriented digital library best illustrate the development phrases of the digital library.  The service-oriented digital library should consist of the following components: three kinds of resources, two service platforms, and one portal. The virtual reference system, as one of two service platforms, is playing an important role in the service-oriented digital library. A distributed collaborative virtual reference system and its framework are presented in the paper, and an automatic task scheduler for the synchronous reference and the asynchronous reference is also described in detail.
