数字图书馆本身就是一个数据集,每个图书馆都可以建立自己的数字图书馆,多个不同地区的图书馆也可以构建数字图书馆。这两种方式的数字图书馆都要进行数据集的交换来实现资源共享,从而来服务用户。基于以上的情况对数字图书馆的信息服务模式的构建从宏观上可以分为单个数字图书馆信息服务的模式和由多个数字图书馆组成的数字图书馆的信息服务。单个的数字图书馆信息服务顾名思义就是对单个图书馆建立数字图书馆,并进行信息服务。单个数字图书馆是 Digital library itself is a data set, each library can create its own digital library, many different regions of the library can also build a digital library. Both types of digital libraries have to exchange data sets for resource sharing to serve users. Based on the above situation, the construction of digital library’s information service mode can be divided macroscopically into a single digital library information service model and a digital library composed of multiple digital libraries. A single digital library information service, as its name implies, is to build a digital library for a single library and conduct information services. Single digital library is
