This paper analyses representative knowledge thoughts in the different developmental stages of information science from the historical perspective. It points out that along the emergence, development and mature of information science,knowledge thoughts in the discipline have gone through the stages of origin,initial development,being marginalized, regaining attention and rapid development. It is also research evolution from the simple idea, imagination and fragmentary theory to scientific concept definition, integral theoretical system in IS. It mainly discusses the documentation researchers like Otlet and Briet's knowledge views which emerged in the original and initial development stage. It also analyses Bush's knowledge viewpoint embedded in Memex in this stage. It points out the reason that knowledge research got less attention in the relatively unattended stage was that technology tradition, information theory and physical paradigm formed the dominating triple development mode, which marginalized knowledge discourse. Cognitive viewpoint, which is regarded as subject knowledge theory, and knowledge thought in IRM are reviewed as for the stage of regaining attention. It analyses the knowledge theme in IS in the rapid development stage from the perspective of both the introduction of corporate KM and the renaissance of knowledge tradition. It also discusses the value and implication of these thoughts to the current knowledge theory research in information science.%本文从历史研究的角度分析了情报学不同理论发展时期出现的代表性知识思想,指出伴随着学科的起步、发展和建制的成熟,情报学中的知识思想经历了从萌芽、产生到相对淡化、重新获得关注和全面兴起的过程,也是从朴素的概念、假说和零散的观点逐步发展成为具有严密的概念界定、系统完整的思想体系的过程.在萌芽与产生阶段,主要讨论了奥特莱、布瑞特等文献学家的知识观,对布什Memex思想中的知识导向进行了分析.在相对淡化阶段,指出知识思想在学科中未受重视的原因是由于技术传统-信息论-物理范式三位一体发展模式的兴起,使知识话语被边缘化,介绍了这一阶段的亮点--社会认识论的主要思想.在重新获得关注阶段,对认识观和信息资源管理中知识观点加以评价,指出认识观是主观知识理论的典型代表.在全面兴起阶段,重点从企业知识管理的引入和学科知识传统的复兴两大取向对学科中知识议题的研究进行了分析.探讨了不同阶段知识思想对当今情报学知识理论研究的意义和价值.
