The new era has raised new requirements for the digital transformation and upgrading of cultural development. The coordinated development of public library services and cultural industry digitization is a concrete manifestation of the advancement of public culture and the cultural industry's digitalization. Based on provincial panel data of China between 2012 and 2021, this paper constructs a dual-system index framework for public library services and cultural industry digitization. Using methods such as the entropy method, coupling coordination model, and grey correlation analysis, the paper measures the comprehensive development level of the dual systems, reveals the relationship between their coupling and coordinated development, and explores the key influencing factors of coupling coordination. The research finds that the overall development level of public library services and cultural industry digitization in China has consistently risen. The annual average value of public library services has always been higher than that of cultural industry digitization, but the gap has been narrowing year by year. The coupling degree and coupling coordination degree of the two systems have also generally shown an upward trend. The coupling degree has remained high overall, while the foundation for coordination has been weak but is improving rapidly. By 2021, the majority of provinces had reached either the transition or coordination stages. Most provinces are characterized by synchronous development or a more advanced development of public library services. The three key dimensions—digital environment, reading services, and service facilities—are most closely related to the degree of coupling and coordination.

Virtual academic communities are currently a primary means of informal academic exchange and an essential part of academic communication. This paper systematically analyzes the relevant literature on users' knowledge behaviors in domestic virtual academic communities, aiming to provide scholars with a comprehensive understanding of the current state of research in this area, thus laying the groundwork for further study. First, the basic concepts of user knowledge behavior in virtual academic communities are defined. Next, through content analysis, the paper reviews research on user knowledge behaviors in domestic virtual academic communities from five key perspectives: user research collaboration behavior, user knowledge sharing behavior, user knowledge contribution behavior, user knowledge interaction behavior, and user knowledge hiding behavior. Finally, the paper critically assesses the current state of research on user knowledge behavior in virtual academic communities in China, identifying several key issues: research topics exhibit a "clustering" phenomenon, research subjects show a "polarized" trend, research methods are "monolithic," and more attention is needed on the study of user knowledge contribution behavior.

Test patterns play a crucial role in the process of converting digital documents into microforms. This article provides an overview of the development of digital document conversion microform technology and offers a detailed interpretation of the national standards regarding the design principles, technical requirements, and testing methods for test patterns. The study also addresses the production of test boards in related practical applications. It identifies three key elements of test patterns: image distortion testing, resolution testing, and density or color reproduction testing. The article proposes suggestions for test pattern design from multiple dimensions, including the refinement of selection criteria, comprehensiveness and applicability of technical requirements, systematic application procedures, standardization of updating and management mechanisms, enhancement of operator skills, and the improvement of supervision and evaluation mechanisms. This research is of significant importance for enhancing the standardization of the digital document conversion microform industry and promoting the improvement of testing standards.

The legislative information services offered by the Sun Yat-sen Library of Guangdong Province include three main aspects: regular information bulletins to meet the basic daily information needs, specialized research support to provide in-depth services in specific areas, and a special service for the "Two Sessions" to offer comprehensive information at key time points. After years of development, the library has achieved significant progress in streamlining communication and feedback channels, establishing a professional service team, innovating service models, and setting up standardized service systems. Legislative information services in public libraries can be improved through the optimization of resource development, shared cooperation mechanisms, enhanced information circulation, and the promotion of collaborative efforts.

Based on an overview of user feedback, human-machine collaboration, and the current research status of human-machine collaboration in smart libraries, this article discusses the advantages of a human-machine collaborative service model based on user feedback in four areas: improving the quality and efficiency of knowledge services, enhancing the user experience in knowledge interaction, promoting the professional development and digital skills of librarians, and improving data-driven decision-making efficiency. The article outlines the construction of the human-machine collaborative service model in four areas: user demand analysis, user service module design, human-machine collaboration mechanisms, and user privacy and security protection. Finally, the article summarizes the measures for constructing this model from three perspectives: digital service support systems, human-machine service teams, and innovative methods for publicity and promotion. The goal is to comprehensively enhance the efficiency of knowledge services and user satisfaction in smart libraries.

Digital twin technology demonstrates significant development potential, and its application in the construction of smart libraries can further drive the transformation of libraries. This paper explains the concept and characteristics of digital twin technology, elaborating on the components of digital twin smart libraries from four aspects: library physical entities, digital twin models, digital twin service systems, and library twin big data. The application scenarios of digital twin smart libraries are described from three perspectives: twin librarian services, virtual creative spaces, and digital memory platforms. Finally, the operational mechanisms of digital twin smart libraries are explored from three dimensions: demand-driven mechanisms, innovation-driven mechanisms, and collaborative mechanisms.

In the context of information development and digital upgrading, transitioning to smart libraries has become the development trend for libraries. As an essential technical support for building smart libraries, the data middle platform plays a crucial role. This paper explores the origin and concept of the data middle platform, as well as current explorations and research in the field. It provides a detailed description of the bottom-up four-layer architecture of the data middle platform in smart libraries: data collection, data systems, data assets, and data services. Additionally, the paper discusses its application scenarios in smart libraries, including business middle platforms, BI systems, intelligent search, personalized recommendations, and management service optimization. Finally, it identifies the development trends of data middle platforms in smart libraries and outlines future challenges and responses in terms of data quality, privacy and security, and technical complexity.

The rapid development of new public cultural spaces is of great significance for the establishment of cultural centers and the branch system for libraries, as well as for promoting the integration of urban and rural public cultural service systems. With support from the policy environment, various regions have vigorously advanced the construction of new public cultural spaces, leading to significant achievements. However, issues such as unclear goals and disorganized evaluation standards remain. The theory of the experience economy highlights the "cultural" attribute of new public cultural spaces, serving as the theoretical foundation for the creation of "cultural experience spaces" and an analytical tool for the shift towards a culturally rich development. Based on the experience economy theory and the practical principles of "new space, new service, and new standard", this paper proposes a practical approach to creat immersive cultural experience spaces, expand experiential cultural service models, and formulate evaluation standards for "cultural experience".

The renovation of existing buildings provides an effective pathway for the construction of public libraries, offering significant benefits for rapidly expanding library coverage and promoting the high-quality development of services. This paper selects 19 cases of existing building renovations from both domestic and international sources through online searches and literature review. Based on case analysis and synthesis, it concludes that the renovation process should adhere to three basic principles: historical preservation, practicality, and cost-effectiveness. The paper also outlines implementation strategies for converting existing buildings into libraries from four perspectives: setting, architecture, function, and facilities. Additionally, it explores four approaches for promoting the high-quality implementation of renovation models: integration-driven, expertise-driven, efficiency-driven, and collaboration-driven.

This paper interprets and analyzes seven stone inscriptions (or rubbings) related to Li Changgeng, a famous naval general of the Qing Dynasty, which are preserved in the Ningbo and Zhoushan areas. The study reveals that Li Changgeng, as a general who embodied the ideal of "benevolence and courage," not only managed military affairs in Ningbo, Zhoushan, and along the Zhejiang coast, but was also actively involved in local education, charity, and public welfare activities. Li Changgeng had a significant influence in coastal regions like Zhejiang and Fujian. These inscriptions reflect his social interactions with local officials and gentry in Eastern Zhejiang, particularly his close relationship with Ruan Yuan, the Governor of Zhejiang. The paper aims to offer a comprehensive understanding of Li Changgeng's activities in Eastern Zhejiang through the interpretation of these seven inscriptions (or rubbings), and to explore the role of Qing Dynasty naval officers in the local social and economic development.

 Currently, there are more than 210 ancient editions of Sanyan and Erpai held in public and private collections both domestically and abroad. A notable recent discovery from the search for Chinese books overseas is the Gujin Xiaoshuo housed in Royal Danish Library, which belongs to the same system as the edition in the Sonkeikaku bunko, but differs from those in the collections of Hosei University and the Cabinet Library in Japan. Furthermore, this article reviews newly discovered Sanyan and Erpai editions in the past thirty years, and through comparative analysis, it explains and discusses the genealogy, significance, illustrations, commentary, and transmission of rare editions such as the Erke Zengbu Jingshi Tongyan housed by the National Library of Russia.
