图书馆是社会需要的产物,它的一切活动以满足社会需要为出发点。现时图书馆的文献信息加工和交流工作,一方面完成了文献信息传递的任务,使文献信息的潜在价值得以发挥,另一方面也促成文献信息的增值。图书馆的活动体现出其自身存在的价值和存在的必要性。图书馆在文献信息交流与传播中的作用将会越来越大。 The library is a product of social needs, and all its activities are based on meeting the needs of society. At present, the processing and exchange of literature information in the library completes the task of document information transmission so that the potential value of documentary information can be brought into play. On the other hand, it also contributes to the appreciation of documentary information. Library activities reflect the value of its existence and the necessity of its existence. The role of libraries in the exchange and dissemination of documents and information will be greater and greater.
