数字图书馆是20世纪80年代末,随着信息技术与网络技术迅速发展,首先在美国和英国建立起来的以局域网络为基础的图书馆网络系统。但是我国的数字图书馆在发展过程中也存在投入不足、从业人员技术水平较低、服务深度和广度不够、尚未建立有效的可持续发展机制、缺乏统筹规划,分工协作不够等问题。这些问题不解决,必将影响数字图书馆的建设。因此应当把如何解决好这些存在的问题作为当前图书馆学研究的一个重要课题。 Digital library is a local area network-based library network system established in the United States and Britain with the rapid development of information technology and network technology in the late 1980s. However, the digital library in our country also has insufficient input in the development process. The low level of technology, lack of service depth and breadth, lack of effective mechanism of sustainable development, lack of overall planning and lack of cooperation in division of labor are all problems. If these problems are not solved, it will surely affect the construction of digital libraries. Therefore, how to solve these existing problems should be regarded as an important issue in the current study of library science.
