科学知识靠积累,科学只能在前人工作的基础上才能获得发展。无论是物理、生物或社会科学领域里的每一种学科,都必须具备一定的手段才能有秩序地积累,增加其科学内容。这些手段之一就是开展编制科技资料索引与摘要的情报基础工作。如众所周知的美国《化学文摘》、《生物学文摘》,《工程学索引》等,如果没有这方面的工作,这些学科在前进的道路上必定遇到很大的困难。美国《医学索引》(下称《医学索引》)从它创刊的早年(1879年)开始,就对它所 By accumulating scientific knowledge, science can only develop on the basis of previous work. Every discipline in the field of physics, biology or social science must have the means to accumulate and increase its scientific content in an orderly manner. One of these means is to carry out the basic work of information technology for indexing and summarizing scientific information. Such as the United States, known as the “Chemical Abstracts”, “Biology Digest”, “Engineering Index”, without such work, these disciplines in the road ahead will encounter great difficulties. The United States Medical Index (hereinafter referred to as “Medical Index”) started its early years (1879)
