在我国 ,大中型图书馆一般都设有基藏书库 ,或称“保存本书库、样本书库”。设该书库的文献原则上不对外开放和流通 ,仅供读者馆内参考查阅。目前 ,随着科学技术的突飞猛进 ,文献数量激增而购书经费严重不足的矛盾日趋激烈 ,读者对信息资源的需求也越来越高 ,各图书馆只好保刊 In our country, large and medium-sized libraries generally have a base library, or “save the library, sample library.” The library set up in principle, the literature is not open to the public and circulation, reference only for reference readers. At present, as science and technology advance by leaps and bounds, the contradiction between the sharp rise in the number of documents and the serious shortage of funds for purchasing books has become increasingly fierce. The readers’ demand for information resources is also getting higher and higher.
