以20世纪90年代中期为界,首先对在此之前文献信息学的理论建设进行简单回顾,结合文献信息学理论的大背景探讨该时期理论建设的局限性。同时针对20世纪90年代中期以后文献信息学的主要观点作了深入和质疑,结合该时期图书馆学研究的主要方向,认为文献信息学应该随着学科的发展不断注入新的内容,不能囿于名称而裹足不前。 Starting from the mid-1990s, this paper first briefly reviews the theoretical construction of the literature informatics before and discusses the limitations of the theoretical construction in the light of the background of the literature information theory. In the meantime, the main points of literature and information science since the mid-1990s of the 20th century were discussed in depth and questioned. According to the main directions of the study of library science in that period, it is believed that literature and information science should continuously inject new contents with the development of disciplines. Name and do not hesitate.
