目前,我国科技期刊多数只编制当年索引,而且是栏目汇总式索引。这类索引虽有一定使用值值,但随出版卷数逐年增加,越来越使读者感到不便。如读者欲查某刊五年内某专业方面文献须翻阅五次年索引,而且像看流水帐那样从头看到尾,费时烦人。出版累计索引当能解决这一难题。但因人力不足,缺乏经费(索引为附加页,且累计索引篇幅多大),难以编制,这大概是多数科技刊物不出累计索引的主要原因。《色谱》编辑部自筹资金出版杂志。近年由于纸张、印刷等价格上涨,亏损加大。在经费与人力都存在严重困难的情况下,为了方便读者,仍决定在1987年第五卷末出版累计索引。为了克服人力,物力不足,就必须用最少的版面编制索引。主题索引科学性强,属上乘,但编制费时费力,且所需篇幅大,一时难做到;分类索引集中,对节约人力物力有利,编辑部在具体做法上作了镇密安排,用较少的人力于较短的时间内圆满地出版了五卷分类索引,同时出版了五卷作者索引。为了与国外习惯 At present, most of China’s sci-tech periodicals only compile the current year’s index, but also the column summary index.

However, due to lack of manpower and lack of funds (the index is an additional page and the total length of the index is too large), it is difficult to draw up the report. This is probably the main reason why most science and technology publications do not have a cumulative index. “Chromatography” editorial self-funded publication of magazines. In recent years, as paper, printing and other prices, loss increases. In the face of grave difficulties in funding and manpower, for the convenience of readers, it is still decided to publish a cumulative index at the end of Volume V in 1987.
