云计算技术的诞生使区域虚拟图书馆成为了未来图书馆建设的发展方向。但思想认识狭隘、经费来源不足、专业人才匮乏、整体规划欠缺、版权意识低下等因素却制约了区域虚拟图书馆联盟资源的共建共享。因此,彻底解放思想、保障资金来源、引进专业人才、挖掘特色资源、妥善解决纷争等是促进区域虚拟图书馆联盟资源共建共享的有效途径。 The birth of cloud computing technology makes the regional virtual library become the development direction of the future library construction. However, the narrow ideological understanding, lack of funding sources, lack of professionals, lack of overall planning and low awareness of copyright restrict the co-construction and sharing of regional virtual library alliance resources. Therefore, emancipating the mind, safeguarding the source of funds, introducing the professionals, excavating the characteristic resources and properly solving the disputes are the effective ways to promote the co-construction and sharing of resources in the regional virtual library alliance.
