文章简述了图书馆服务范式的演进历程,将图书馆服务范式分为文献范式、信息范式和知识范式三个阶段,并阐述了三者之间应为继承、渗透和发展的关系。认为知识范式是当下图书馆发展的必然趋势,新范式的形成反过来又会对图书馆哲学思想产生深刻影响。 The paper briefly describes the evolution of library service paradigm. It divides library service paradigm into three stages: document paradigm, information paradigm and knowledge paradigm. It also expounds the relationship between inheritance, infiltration and development. It is believed that the paradigm of knowledge is the inevitable trend of the current library development.
