To this end ， from the perspective of subject content， a method for measuring the degree of integration of library ， information and archives is proposed. Firstly， according to Zipfs law， the subject words are empowered. Secondly， the Jaccard similarity coefficient is improved to measure the similarity of the subject content. Thirdly ， the integration degree of the integration index is proposed. Finally， Journal of the Library Science in China ， Journal of the China Society for Scientific and Technical Information and Archives Science Study are empirically analyzed. The results show that there is a gradual integration of the three in some areas， but the scope of the subject matter of the fusion and the degree of integration are still limited to a certain extent， that is， no obvious and dramatic change. 1下载后可任意编辑 Keywords Subject content.
