随着近代科学技术的发展,科技文献资料的数量正急剧增长。近年来,全世界每年发表的科技文献达三、四百万篇,每年增加几十万篇。有关化学的情报资料也急速增长。据美国《化学文摘》报导,1907年摘录文献11,847篇,1977年则达436,887篇;1980年每期约摘录6～7千篇。1975年Brooks等研究分析化学文献的进展时曾指出,若保持过去20年的发展趋势,至1980年,分析化学的文献量则可望按所得的指数增长率递增,每年将超过4万篇。据称,世界上科技文献量的倍增时间约15年,化学文献的约8～10年,分析化学的约5～7年(在1956年至1972年期间)。可见,分析化学的文献增长速率是很快的。
With the development of modern science and technology, the number of scientific literature is rapidly increasing. In recent years, science and technology documents published in the world each year amount to three or four million articles, increasing hundreds of thousands of articles each year. Information on chemistry also grew rapidly. According to the U.S. “Chemical Abstracts,” 11,847 articles were extracted in 1907 and 436,887 in 1977; and 6-7,000 were extracted in each of the 1980’s. In 1975, Brooks et al. Made the analysis of the progress of analytical chemistry literature. He pointed out that if the development trend of the past 20 years is maintained, by the year 1980, the amount of analytical chemistry literature is expected to increase at an exponential rate of increase, exceeding 40,000 annually. Allegedly, the amount of scientific and technological literature in the world doubling time of about 15 years, about 8 to 10 years of chemical literature, analytical chemistry of about 5 to 7 years (between 1956 and 1972). Visible, the analytical literature of the literature growth rate is fast.
