有关图书馆知识公共性的讨论是一个理论与实践兼具的话题。其理论上的探讨需要从对知识本质的哲学追问开始,兼顾其他学科视域中的知识观点。而从实践的一面看,图书馆知识的公共性又与图书馆在知识社会进程中的作为密不可分。因此,对图书馆知识公共性的把握,需要在语境的融合中展开,即:哲学一般意义上的公共知识、经济学视角下的公共物品以及知识管理语境中可获得的知识。 The discussion about the publicity of library knowledge is a topic which has both theory and practice. The theoretical discussion needs to begin with the philosophical inquiry into the essence of knowledge and give consideration to the viewpoints of knowledge in other disciplines. From a practical perspective, the commonality of library knowledge and the library in the process of knowledge-based society are inseparable. Therefore, to grasp the commonality of library knowledge needs to be carried out in the fusion of contexts: public knowledge in the general sense of philosophy, public goods in the perspective of economics and knowledge available in the context of knowledge management.
