Accessibility services in public libraries,as a part of the barrier-free environment,are committed to helping special groups such as people with disabilities to enjoy public cultural services and participate in digital life. Metaverse brings new ideas and new vitality to such special library services. This article summarizes the breakthroughs in accessibility achieved by public libraries,develops a service system,and explores the way forward for accessible library services,by elaborating the development and changes in the services at different stages of the Internet. Public libraries should make multiple breakthroughs in their accessibility,ensure convenience and equitable access to services driven by user needs,and bridge the digital divide and promote social inclusion with the help of metaverse-related technologies.

The article takes 31 provincial public cultural development policies during the 14th Five-Year Plan period as the research sample,and adopts the content analysis method to build an analytical framework of four dimensions：objectives,subjects,contents,and methods,revealing the commonality and characteristics of public cultural development plans in each province. Based on this,the regional development strategies of public culture in China are analyzed in two dimensions：common construction focus and characteristic construction key points. It also proposes policy implications for the development of basic public cultural service standards,cultivation of grassroots public cultural professionals,deepening the reform of corporate governance structure of public cultural institutions,expanding the branding effect of distinctive public cultural spaces and activities,forming a cross-regional regular support mechanism,and exploring the inter-provincial service model of "alliance - main branch" of public cultural institutions.

Based on the theory of public policy change,this paper takes China's digital literacy education policies as the research object. With the help of Nvivo12 qualitative analysis and SPSS statistical analysis software,it conducts quantitative statistics and interactive analysis on the enactment time and policy subjects of 87 Chinese digital literacy education policies from 2002 to 2022 . The study finds that the evolution of China's digital literacy education policy is based on promoting the all-round development of all people,taking the practical needs of economic and social development as the entry point,building a lifelong digital learning system as the breakthrough point,and focusing on the coordinated integration of urban and rural areas for shared benefits. At the policy gap stage,the main focus was on infrastructure development and the application of information technology in education,and digital literacy education did not receive much attention;at the early exploration stage,the focus was on building digital resource platforms,and attention was paid to the development of digital citizens;at the initial policy-making stage,the concept of "digital literacy" was formally introduced,and the exploration of digital literacy education began,focusing on the construction of digital government and digital literacy education for the elderly and a supervisory mechanism was gradually established. At the stage of comprehensive policy development,specific policies on digital literacy education were issued to formally define the connotation of digital literacy education,and digital literacy education for citizens was fully rolled out,initially integrated into education,rural revitalisation,community governance and other fields,and emphased the construction of a lifelong digital learning system. Promoting the deep integration of all-field digital literacy education will be an important issue in the future. Therefore,it should further strengthen the integration of digital literacy education policies into the economy,society and life,accelerate the transformation of an elderly friendly digital society and the digital transformation of enterprises by seizing the opportunity of digital literacy education,and enhance the ability to work efficiently and digitally,so as to better achieve the goal of improving digital literacy for all.

Analyzing public health policies from the perspective of policiometrics is good for objectively evaluating current policies and providing scientific advice for subsequent policy setting,which is of great importance in promoting the scientific and rationality of the policies. This paper proposed a policiometrics research framework based on keyword analysis and IPTC media topic taxonomy,and takes the public health policies as an example for empirical analysis,conducted the policy analysis from the perspectives of policy keywords and policy classifications. It is found that the policiometrics research framework proposed in this paper plays an important role in the analysis of public health policies,and can fully analyze the characteristics of policies from three aspects：theme comprehensiveness,time responsiveness and policy effectiveness. At last,advices are suggested from the establishment and improvement of policy classification system,the citation of scientific literature,and the improvement of cross-language policy processing technology.

Liu Kwoh-Chuin's What is Library Science has been an academic canon in Chinese Library Science,and its canonization deserves our close attention. This paper first defines what is an academic canon,and then explores the internal and external causes in the canonization of What is Library Science. The result shows that What is Library Science has valuable theoretical innovations,which is the internal cause of its canonization. After its publication,it was only hotly discussed for a short time,and then encountered a long period of critique and misreading. Since the 1980s,it has been reread,interpreted,repositioned and revaluated by many scholars,and then recognized and accepted by historical works,symposiums and textbooks of Chinese Library Science,which promotes and confirms its position as an academic canon.

A total of 23 Chinese library standards were published in 2021,and 4 library national or industry standard formulation programme projects were established. The achievements are mainly reflected in the updated release of Public Library Professional Work Specifications,the focus on issues such as library intellectualization and space construction,the emergence of social organization standards,and the expansion of library service standard system.

As a new generation of general AI technology,ChatGPT brings great opportunities for the industry to grow,but the threat it poses to the security of personal information is also a cause for concern. The main risks to personal information security posed by ChatGPT include illegal collection,over-mining,information leakage and algorithm bias. Traditional principles of fair practice are not applicable in addressing the challenges of ChatGPT,and the theory of "protection by design" can provide a solution to this dilemma through the integrated governance of ethics,law and technology. "Protection by design" of personal information in the operation of ChatGPT should adhere to the basic principle of being “people-oriented” and meet the algorithmic ethical requirements of security,fairness,controllability and accountability. Specific protection needs should be determined based on the investigation of application scenarios,the classification of personal information,the analysis of the impact of rights and interests and the assessment of security risks. A holistic protection system should be established through the identification of elements,selection of measures,process design and programme evaluation.

From 2018 to 2022,under the strategies of building a strong cultural nation and province,the high-quality development of public cultural services,the promulgation of the "Public Library Law",and the challenges of the COVID-19 pandemic,public libraries in Guangdong province have embraced new opportunities and challenges,and maintained a steady and progressive development trend. Based on the data of the seventh national evaluation and rating of public libraries above county level in Guangdong province and the data of Guangdong Library Association on the development of public libraries,the report illustrates the overall situation of the development of public libraries in Guangdong province from 2018 to 2022,focusing on the development background,the overall development status,the practices and achievements of the high-quality development,and the construction of people-centered libraries. The development of public libraries in Guangdong province has made tremendous achievements：library service system has been extended to both urban and rural areas;library facilities have been upgraded;library funding has been kept balanced and powerful,documentary and information resources have been continuously optimized;professional talent team has been constantly expanded;and library services have been significantly improved.

In order to provide reference for the development of public library health information service in China,this paper establishes an Interpretative Structural Model（ISM）for the factors which influence public library’s health information service supply,and analyzes the hierarchical relationship of each factor and its influencing mechanism. By reviewing and summarizing relevant research results,this paper identifies 26 factors affecting the supply of health information services in public libraries based on expert surveys and reader interviews. It goes on to classify and summarize the factors. Then,the relationship between the influencing factors is established by means of experts grading method;an adjacency matrix is developed;and the accessibility matrix is calculated. The paper breaks down the accessibility matrix,and categorizes the influencing factors of public library health information service supply at 8 levels. Creating an explanation structure model based on expert consultations,it analyzes the specific mechanism of the factors affecting the supply of health information services in public libraries at various levels. The study suggests the influencing factors of public library health information service supply can be divided into 4 levels,i.e.,user orientation,internal environment,external conditions and deep institution. User-oriented factors have direct impact on public libraries’ supply of health information service;internal environment and external conditions are indirect factors;while deep institutional factors are fundamental for the supply.

Strengthening research on the diffusion of national reading policies and understanding the characteristics and influence of the policies could help enhance the scientific nature of their formulation and publication,and improve their implementation effects. With a sample of national reading policies in China,this article reviews the references between the policies by means of time-series analysis and social network analysis,measures the four dimensions of policy diffusion：intensity,breadth,speed and direction,and summarizes the characteristics of policy diffusion. It is found that：The diffusion of national reading policies presents a characteristic of temporal clustering：between 2012 and 2017;National reading policies in Legal category leads the way in diffusion intensity,breadth and speed,which is the absolute authority and guidance,followed by the Plan category and Decision category,and the weakest are the Opinion category,Notification category and Program category;The national reading policies normally diffuse in two ways：top-down diffusion and horizontal diffusion. Central policies often take the up-down direction while the local policies mainly diffuse horizontally. This study proposes the optimization suggestions from three aspects：establishing and improving the release and diffusion system for national reading policies,selecting the appropriate policy category and issuing agencies,and opening up the vertical diffusion path of national reading policy.

The implementation and governance of public digital cultural services cannot be achieved without the guidance and regulation of public policies. Analyzing the content structure of relevant policies can provide a reference for optimizing policies and promoting the coordination of participants. This study develops a two-dimensional analysis framework of "policy tool - policy participant",coding and performing a quantitative analysis of the texts and structures of 84 key digital cultural service policies. The study suggests that the use of policy tools is extensive but unbalanced;talent training and financial investment in supply-based policy tools are insufficient;environment-based policy tools are weak and have only one way to evaluate their effectiveness;demand-based policy tools rely heavily on the government,the participation of public welfare cultural institutions is diverse but their role is limited,and the primary role of public and grassroots communities is not prominent enough. Therefore,this paper proposes to establish a comprehensive portfolio of policy tools,to call on social forces to engage in talent training and funding,to establish an all-round effectiveness evaluation mechanism,and to stimulate the engagement of social actors in various ways,while giving full play to the role of governments at all levels.

In recent years,along with the rapid development of public libraries,the development of professionalism is facing the challenges of the functional positioning of public libraries with Chinese characteristics,the advancement of applied technology in the field of public libraries,the tendency of public libraries to be "administrative-oriented",and the shift in the development of library discipline. In line with the changes of the times and the development of librarianship,public libraries can not use the traditional concept and thinking of specialisation to meet the needs of the new era and the new development. It is necessary to develop a theoretical system,an academic system,a disciplinary system and a discourse system of public libraries with Chinese characteristics based on the theory of modern public cultural services,taking the protection of people's cultural rights and interests and the enhancement of people's spiritual strength as the main social functions,and the promotion,guidance and services to forster a love of reading among Chinese people as the main tasks;and it is necessary to develop a new concept and new capacity for the professional development of public libraries,which mainly includes enhancing the capacity to promote,guide and serve the national reading campaign,improving the capacity to promote the socialisation development of public libraries,and strengthening the capacity of integrated development with distinctive characteristics.

In the digital transformation society,library is a transformative force for advancing cultural self-confidence and self-improvement,and the overall layout of digital China and the national cultural digitization strategy provide policy guidance for the library to open up a new prospect of high-quality development. Using the methods of literature review,practice survey,and content analysis,this article attempts to sort out the current situation and requirements for the high-quality development of library in the era of digital transformation,analyze the international policy orientation of library digital strategy,and propose a development path for China. The study indicates that the high-quality development of library in the era of digital transformation needs to meet the requirements of “people-centered” transformation and form an ecosystem that is open,intelligent,inclusive,and sharing;data empowerment,demand-driven,digital intelligence integration,value-led and innovation-driven are the important strategic directions of foreign libraries' digital strategies,which play a normative and guiding role in reshaping and integrating the core elements of high-quality development of library. To serve the vision of building a strong cultural nation,and to meet the requirements and expectations of the country,the people,the society,and the era,library should transform and renew itself in terms of system,concept,business format,and capacity under the overall layout of digital China.

Research highlights,special texts with a promotional function that outline the research methods and conclusions of an academic paper,can facilitate the advancement of knowledge exchange and scientific innovation. Based on 564 paper highlights from the ScienceDirect database,this paper explores the internal and external characteristics of research highlights,analyzes its linguistic features by means of multidimensional analysis （MDA） method,elaborates on the differences between the linguistic features of highlights and abstracts,examines the relationship between the citations of papers and the linguistic features of highlights,and proposes some suggestions for highlight-writing. With the help of manual annotations,the paper identifies the topics of the highlights from an integrated and a categorized point of view respectively,using the LDA model and the VOSviewer tool. The results show that：highlights are generally more informative and non-narrative,with clearer expressions,less interactive and explicit persuasiveness,and a relatively high degree of objectivity and precision;highlights of highly cited papers tend to use more cardinal numbers,quantifiers,emphases and independent or coordinate clauses,demonstrating specific data and their correlation;highlights can be divided into method-based highlights,conclusion-based highlights and （to a lesser extent） other highlights,which indicate the key information of a scientific field,unfolding the innovative methods and focuses in the field.

Based on the pilot projects gradually launched in the construction of primary-level public cultural service systems in Guangzhou since 2022 and the basic theories of a community with a shared future for mankind,the common human values and national governance construction,this article analyzes the new concept,idea and model of the public cultural community proposed by Guangzhou City. The article believes that the public cultural community is conducive to achieving transformation and upgrading in four aspects：from the public cultural service system to the public cultural cooperation alliance,from public cultural social participation to public cultural citizen participation,from public cultural security to public cultural influence,from public cultural co-construction and sharing to public cultural co-governance and co-creation. The article believes that the public cultural community is conducive to reflecting the values of public cultural rights,common interests of public culture,public cultural efficacy and public cultural governance. The article points out that the implementation of the public cultural community from "public culture+" to "public culture×" transformation and upgrading is an inevitable trend of the construction of primary-level public cultural service systems.

The Library of Congress is the main repository of Chinese books in the United States. The history of collecting Chinese books in the United States from 1912 to 1949 had its own unique driving factors,which were not completely synchronized with the history of Sinology. From the perspective of philology,the history of the collection of Chinese books in the Library of Congress from 1912 to 1949 can be divided into three phases. The first phase,1912-1949,was the period of collecting the basic classics,during which a large number of documentary resources and philological experiences were accumulated;the second phase,1926-1941,saw the acquisition of an enormous amount of private collections,which increased the Library’s rare book holdings;the third phase was from 1942 to 1949,after the outbreak of the Pacific War,when the new accessions were mainly contemporary materials and traditional Chinese books as cultural heritage were no longer acquired after 1949. In parallel with the accumulation of Chinese books in the collections,the level of bibliography and bibliology of Chinese books in the Library of Congress was greatly developed,serving as an important basis for the development of sinology in the United States.

Learning interaction during the information retrieval process is an integral concept,including the interactions between user and search system（U-S）,search engine result page（U-SERP）,search content（U-C）,other users（U-U）,and so on. Collaborative search further increases the complexity of the learning interaction. This paper designs an information search experiment to explore the effects of social relationships and collaborative efficiency（or,collaborative effectiveness） on users' learning interaction,thus laying a foundation for understanding users' collaborative learning mechanism. Using two-factor ANOVA,Mann-Whitney U nonparametric tests and qualitative analysis,this paper comprehensively analyses the data generated in the experiment. The study shows：Social relationship type does not affect the learning interaction in collaborative search;Collaborative effectiveness has a main effect on the depth of web links,the number of knowledge discussions,and the amount of knowledge sharing among users;Social relationship type and collaborative effectiveness have an interaction effect on the average browsing time of users. The average browsing time of the friend group is higher than that of the stranger group at the high level of collaborative effectiveness,while the average browsing time of the stranger group is higher than that of the friend group at the low level of collaborative effectiveness. The study can encourage information seeking users to attach importance to collaborative learning,and serve as a reference for designing collaborative information retrieval systems to support better learning experience.
