大数据时代，网络学术资源建设快速发展，大有取代数字图书馆之势。在这样一种背景下．数字图书馆建设要有大数据思维：在资源建设方面，要拓展资源范畴，增加资源整合的广度，加强资源组织加工的深度：在技术应用方面，重视语义技术，加强聚类技术的应用，广泛应用数据分析技术，提升检索技术与水平；在服务方面，丰富数字图书馆服务产品，服务模式由被动、等待、共性化转向积极主动、自动推送和个性化。未来数字图书馆要跳出传统资源建设的框架，树立全方位服务的理念，提供全资源服务，拓展服务方式和传播形式，数字图书馆馆员应该立志成为数据分析家。

英文摘要：

With the rise of academic resource database vendors in the big-data era, several important vendors in China, such as CNKI, Wanfang, Weipu and Superstar database as well as some online resource vendors, such as Baidu, are developing rapidly in the resource construction in respect to the academia, education and culture. These resource construction vendors are continuously expanding their information resources and at the same time diversifying the forms of service. It will cause great threat to the survival of digital libraries. The issues such as how the digital library survives and develops, whether it will be replaced etc, must be paid great attention to. Therefore, the original concept about resources, organizational resources, technology, services and functions of digital libraries should be changed, and the infrastructure of digital libraries should be reconstructed. In this way the current challenges might be turned into opportunities for the rise of digital libraries. The article reviews several related research works and summarizes some important researches and their main achievements in the big data era of digital libraries. Learning from the resource vendors, we propose to use big data thinking to construct digital libraries in the era of big data. The major points of this paper are described as follows： In the aspect of the development of a digital library, we propose to extend the resources of digital libraries by including not only the information in literature but also the information from governments, network with broad social concerns; We also suggest to expand the scope of resource integration in digital libraries, which aims at not only integrating resources within the library, but also integrating the information resources from social point of view and from the network platform, especially integrating the resource useful in solving com- plex problems; furthermore, to improve the depth of process for digital library resource organization, it is necessary to pay more attention to the deconstruct
