国务院所属十一个部委(包括冶金部)1980年4月起联合在香港建立了国际联机检索终端机,查找美国DIALOG系统和ORBIT系统数据库的文献.冶金部门一年多来,先后试验了几十个课题,找到了若干有用的文献,受到有关用户的欢迎.我所1981年下半年起已正式为全国冶金系统各单位办理国际联机检索业务.国际联机检索是利用电子计算机和通讯卫星远距离进行人机对话,并当即自动输出检索结果的现代化情报系统.它具有检索速度快、效率高和费用低的优点,一般查找一个课题只需几分钟至十几分钟,平均收费30元左右,也可联机订购国外原始文献的复制体.数据库内容非常广泛,有工程技术、经济管理、市场行情、政府文件、专题研究报告、学位论文、专
