1 美国科学引文索引(Science Citation Index,SCI) 1963年创刊,由美国科学情报所编辑出版,为一种大型多学科综合性检索工具,也是一种比较科学的检索体系。由于编制方法独特,通过揭示引证与被引证的关系,可以沟通当年、几年、几十年甚至上一世纪与当前作者和学科之间的关系,已越来越被人们所认识与采用。它收录了世界上约43个国家和地区3000多种重要科技期刊,年收集论文数量为60万条以上。目前,为了制定科学指标,调查分析国力,一些国家如美国、苏联、联邦德国、英国、匈牙利等都利用此种工具进行论文统计与分析。
1 The Science Citation Index (SCI) was first published in 1963 and edited and published by the American Scientific Intelligence Agency. It is a large multidisciplinary comprehensive search tool and a relatively scientific search system. Due to its distinctive method of preparation, it is more and more recognized and adopted that, by revealing the relationship between citation and citation, it is possible to communicate the current author’s and discipline’s relationship with the current year, years, decades or even the last century. It contains over 3000 kinds of important scientific and technical periodicals in about 43 countries and regions in the world and collects over 600,000 papers a year. At present, in order to formulate scientific indicators and investigate and analyze national strength, some countries such as the United States, the Soviet Union, the Federal Republic of Germany, the United Kingdom, Hungary and other countries have used such tools for statistics and analysis of theses.
