任何图书馆都没有能力收集读者需求的所有文献 ,而只能有选择地补充馆藏。图书馆的性质与任务、藏书的补充方式和经费问题都是图书馆藏书补充的影响因素。图书馆应树立使用权意识、借助资源共享 ,利用Internet资源 ,最大限度地满足读者的需求。 No library has the capacity to collect all the literature of readers’ needs, and only replenish it selectively. The nature and mission of the library, the ways of supplementing the books and the financial problems are all the influential factors in supplementing the library collections. Library should establish awareness of the right to use, with the help of resources sharing, Internet resources, to maximize the reader’s needs.
