参照基于数字化资源的数字图书馆、基于集成信息服务的数字图书馆、基于用户信息活动的数字图书馆3类范式,提出数字图书馆的3类体系结构,并相应将数字图书馆的运行模式和服务模式归纳为单向服务型、双向交互型、个性设计型,初步建立统一的数字图书馆理论模型,进而探讨数字图书馆的运行动力。 According to the digital library based on digital resources, the digital library based on integrated information service and the digital library based on user information activities, three types of digital library architecture are proposed, and the operation modes of digital library and Service model is summarized as one-way service, two-way interactive, personality design, the initial establishment of a unified digital library theoretical model, and then explore the operational power of digital libraries.
