前言 期刊是科研成果的记载,是人类科学技术发展的记录。它出版周期快,学术观点新颖,内容丰富,反映了新技术、新成果、新观念,具有极大的情报价值,在世界所有文献类型中,它含有70％的科技情报。正因为如此,期刊越来越受到人们的欢迎,而成为各高校及研究机构图书馆收藏的重点。但由于期刊数量非常庞大,任何一个国家都不可能收齐全世界上所有期刊,更何况一个单位。特别是在中外文期刊逐年大幅度涨价,各高校图书馆普遍经费困难的情况下,急切需要针对馆情以及读者对科技情报实际需求,研究科技期刊采购的新原则及科学的采购方法。

Its publication period is fast, academic point of view is novel, rich in content, reflecting new technologies, new achievements, new ideas, with great intelligence value, in all the world literature types, it contains 70% of the scientific and technological intelligence. Because of this, the periodicals are getting more and more popular, which has become the focus of the collection of libraries of universities and research institutes. However, due to the huge number of journals, it is impossible for any one country to receive all the journals in the world, let alone one unit. Especially in the case of Chinese and foreign journals, which have experienced a drastic price hike year after year and have difficulty in general funding for all academic libraries, there is an urgent need to study the new requirements of science and technology information and the new principles of scientific and technological periodical procurement and scientific methods of procurement in view of the actual conditions of readers and libraries.
