定题服务就是围绕研究课题,对情报加以收集、筛选、整理,然后将它们定期或不定期地提供给用户。定题服务有效地发挥了情报资料的作用,大大缩短了专业科研人员查找文献资料的时间,解决了他们找不全和看不完的问题。这一效果从我们的工作经历中可以充分反映出来。例如针对有色研究室“从冶炼废料中回收银”这一专题,我所情报人员主动深入到专题组,了解他们所需资料的范围和要求,再据此在各种期刊杂志上系统地进行查找。中文方面的资料,复制后即时送去,有关外文资料,也及时翻译出来,汇编成册,提供给他们。前后只用一个 Fixing service is to focus on research topics, intelligence collection, screening, sorting, and then provide them regularly or irregularly to the user. The fixed-topic service has effectively played the role of intelligence information, greatly shortening the time for professional researchers to find documents and documents, and resolving the problems they find incompleteness and indefinableness. This effect can be fully reflected in our work experience. For example, in response to the topic of “Recycling silver from smelting waste” in colored research labs, our intelligence personnel took the initiative to deepen their understanding of the scope and requirements of the information they needed and conduct systematic searches in various periodicals and magazines accordingly .
