UNISIST模型是20世纪六七十年代联合国构建全球科学信息系统计划的基础性研究成果,是一个关于科学交流的相当完备的模型。它明确提出正式交流渠道、非正式交流渠道和表单渠道三种信息交流途径,并突出出版社、科学图书馆等信息中介机构在科学交流活动中的重要价值。进入新千年以后,Fjordback Sφndergaard等情报学者对UNISIST模型做了适应数字化环境的改造,以反映数字技术、地域以及学科等因素对科学交流图景的影响。
The UNISIST model is a fundamental research result of the United Nations’ plan to build a global science information system in the 1960s and 1970s. It is a fairly complete model of science exchange. It clearly put forward formal exchange channels, informal exchange channels and form channels three kinds of information exchange channels, and highlight the important role of publishing agencies, science libraries and other information agencies in science exchange activities. After entering the new millennium, information scientists such as Fjordback Søndergaard made some modifications to the UNISIST model to adapt to the digital environment to reflect the influence of digital technologies, regions and disciplines on the science exchange landscape.
