Abstract: [Purpose/Significance] As smart libraries based on technological innovation brings an impact on the original way of books arrangement in open stacks and a library's evaluation standard, it is necessary to study the optimized way of books arrangement under the new research environment.[Method/Process] This paper takes the criteria for books arrangement in the provincial public libraries for the sixth national public library assessment as an example, which require that libraries should classify open stacks into the third catalogue, and the correct ration is 80%. It brings deficiencies in theory and practice, such as logical irrationality between the classification grade and the accuracy of the book arrangement, too massive books within a single third category, damage of the classification standards which are sub-divided beneath the third catalogue; inconvenience of finding the same kind of books for readers or working for librarians, disintegrating cataloging and books shelving. In the analysis of causes of the defects, this paper concludes that it is mainly because the research of books arrangement in open stacks is insufficient, smart libraries bring technological impact and the criteria for book arrangement method are immature and unstable.[Results/Conclusions] In the age of smart libraries, the multi-party collaborative research should seek for the multi-compatible linear shelving system with "threshold" as the unit; the characteristics of man-machine compatibility between original shelving methods and technological innovation of the libraries should be clarified and its application should be lightly tuned; improving the assessment standards of open stacks book arrangement, so as to improve the internal management and external evaluation of smart libraries.
