基于P2P技术的数字图书馆虚拟联盟的诞生,克服了数字图书馆实体联盟之间缺乏灵活的、有效的动态整合机制的难题。由于虚拟联盟没有中心节点和管理机构,作品的传播难以控制,著作权侵权责任更难以划分。在虚拟联盟中,作为实体机构的数字图书馆主要扮演着者ICP和ISP两种角色,其侵权的方式和责任的认定各不相同。 The birth of digital library virtual alliance based on P2P technology overcomes the problem of the lack of flexible and effective dynamic integration mechanism between digital library entity alliances. Because there is no central node and management organization in the virtual alliance, the dissemination of the works is difficult to control and the responsibility of copyright infringement is more difficult to divide. In the virtual alliance, the digital library that serves as an entity mainly plays the roles of ICP and ISP, and the way of infringement and the determination of responsibility are different.
