In recent years, several studies have comprehensively reviewed past research results to reveal the main issues, concerns, and research topics in the field of public libraries and public spheres. These studies have elucidated that the research theme of public libraries as a ‘meeting place’ has received increasing attention. They also noted the need for quantitative approaches in this field. Addressing this requirement, we conducted quantitative topic modelling using latent Dirichlet allocation and established an overview of research topics in the literature related to public libraries as public spheres. The following four periods emerged: first period (1993–2003), second period (2004–2010), third period (2011–2015), and fourth period (2016–2022). By analysing a cross-section of research topics from all periods, we elucidated the transitions of research themes developed in the research field. In addition, our comparison of topic model maps and topics over the years revealed that research topics appear to have become increasingly complex. Research topics on meeting places in public libraries have emerged continually and changed over time, covering (1) places for individual civic group activities, (2) public spaces where patrons face diversity and pluralism, (3) community spaces where patrons foster social trust, and (4) social spaces where patrons build social capital in the community. This result indicates that the research on public libraries as public spheres has gradually developed based on these venues being meeting places and will continue to progress.","PeriodicalId":501489,"journal":{"name":"Libri","volume":"72 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142218515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study took students from key junior high schools in Nanning, Guilin, and Liuzhou as the research subjects. The UTAUT model retained three factors, performance expectation, effort expectation, and social impact, while introducing two variables, perceived risk and immersive experience, to jointly develop a factor model for the digital reading behavior of junior high school students in Guangxi. After conducting a questionnaire survey using an “online + offline” method, 497 valid questionnaires were obtained. SPSS 23 was used to perform reliability and validity analysis and descriptive statistical analysis, while AMOS 26.0 was used to conduct discriminant validity analysis, model adaptation analysis, hypothesis testing, and path analysis. The research conclusion was that performance expectations, effort expectations, social impact, and immersive experience all had a positive and significant impact on the digital reading willingness of junior high school students; performance expectations, effort expectations, social impact, and immersive experience positively influenced their digital reading behavior through their digital reading willingness, while perceived risk was found to have no significant impact on digital reading willingness and corresponding behavior. This article used a composite research method to study a sample of student groups in specific regions. It was an early introduction of immersive experience and perceived risk indicators in the study of digital reading behavior, specifically exploring the digital reading patterns of junior high school students who had received less attention in previous studies but were in a critical period of growth.","PeriodicalId":501489,"journal":{"name":"Libri","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142218513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally regarded as the custodians of knowledge, libraries must adapt to these changing dynamics of the digital world while preserving their core principles. This study looks into the strategic integration of advanced technologies, aiming to redefine the mission of libraries in the face of complex challenges. The Fifth Industrial Revolution encompasses a convergence of diverse technologies, including the Internet of Things (IoT), cloud computing, biotechnology, nanotechnology, and quantum computing, all underpinned by the currency of data. Artificial intelligence (AI) is a focal point, promising enhancements in user experiences and operational efficiency, however, it also raises critical ethical and privacy concerns that challenge fundamental library principles. This research employs an interpretive content/document analysis approach to examine the evolving roles of libraries, considering their pivotal function in bridging the digital divide, providing equitable access to technology and digital resources, advancing research and innovation, and fostering community engagement. The study underscores the imperative to address challenges related to data privacy, digital inclusion, resource allocation, intellectual property, and sustainability. However, despite these challenges, libraries are poised to remain indispensable pillars of education, research, and community interaction. To do so, they must embrace technology strategically to redefine their roles and expand their influence within evolving knowledge systems.","PeriodicalId":501489,"journal":{"name":"Libri","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141506354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The novelty of this study consists in its parallel analysis of both librarians’ and users’ perspectives on librarians’ roles and abilities in optimizing access to information. The results obtained by means of interpretative qualitative analysis combined with descriptive quantitative analysis revealed that Romanian librarians succeed in providing good information services, however, the demands and expectations of users highlight a continuous need for integration of librarians into the mission of the universities and research institutes, and knowledge sharing and a series of innovations are recommended. The results obtained by interpretative analysis, combined with quantitative analysis for corroboration, point to four interrelated themes regarding the Romanian librarians’ roles and abilities in optimizing access to information. The first principal idea is that librarians’ abilities and competencies are key assets for Romanian academic and special research libraries. The second is that Romanian librarians need training in knowledge management and quality management. The third is that embedded librarianship and knowledge sharing could add quality to libraries services. Finally, the fourth is that competency management can determine engagement of Romanian librarians in improving access to information.","PeriodicalId":501489,"journal":{"name":"Libri","volume":"187 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141506353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Haile","doi":"10.1515/libri-2023-0109","DOIUrl":"https://doi.org/10.1515/libri-2023-0109","url":null,"abstract":"Abstract The digital divide, in my view, is not only created due to the lack of local contents but also due to the fact that few digital contents from local sources are found in the digital libraries of higher education in Ethiopia. Likewise, the creation and dissemination of local contents could be facilitated not only by the presence of local digital contents but also by the presence of usable digital technology at a local level. This article aims to give a practical solution to bridging the digital divide by unlocking local heritage knowledge through creating digital contents from locally grown literary heritage as well as by developing a localised digital library system. Therefore, this article presents the research processes and results that were undertaken to unlock local heritage knowledge and developed the localised digital library system: customising a free and open-source software; digitising and translating the local literary heritage contents; and building the digitised and translated literary heritage contents into the localised digital libraries, which Greenstone digital library software was used to customise into local use. The English version of the Greenstone user interface (macro files) was translated into the Tigrinya language, one of the locally spoken languages in Ethiopia. For translation purposes, a list of suitable and compatible Tigrinya words and phrases that basically fit with the meaning of the English version of the Greenstone spreadsheet was developed. As a result of this translation work, the Tigrinya language interface has become one of the languages that are included in Greenstone digital library software version 2.83 for the first time (Language short name=ti “long name=ትግርኛ (Tigrinya)” default encoding=utf-8). To unlock the heritage knowledge and build the localised digital library with local digital collections, a sample of Ethiopia’s ancient Ge’ez parchment manuscripts were digitised and translated into Tigrinya and English languages. To facilitate the retrieval of information and to be easily recognised by internet search engines in the Tigrinya language, a local specific metadata standard for Ethiopia’s ancient Ge’ez parchment manuscripts was developed at three hierarchical levels, at manuscript level, at chapter level and at page level, with each translated page tagged using HTML. To facilitate the link between the translated text and the corresponding digital image, an “item” file was created using a WordPad. As a result, three collections were built into the customised digital library: the digitised image of the Abushakir manuscript as well as the Tigrinya and English translated texts of the same manuscripts. The functionality and usability of the localised digital system was tested by searching keywords and browsing titles from the built collection of the Tigrinya text and the original digital image of the manuscript.

However, it has also brought to light the existence of a digital divide, exacerbating the hardships faced by those who are digitally excluded. Amidst the turmoil of the crisis, there has been limited attention given to addressing the digital divide in developing countries including Malaysia. In response, Malaysian universities swiftly transitioned to online learning to curb the spread of the contagion. Nonetheless, this rapid shift has inadvertently marginalized underprivileged students, hindering their access to the benefits of online education. Employing the three-level digital divide framework, this study aims to probe into the extent of the digital divide among Malaysian university students and evaluate its progression. Through mean score and frequency analyses, we assessed the magnitude of the digital divide among these students. Furthermore, we employed partial least squares structural equation modeling to gauge the flow of the digital divide from the initial level to the third level. Subsequently, we examined the mediating roles of material access, digital skills, and digital usage. The findings revealed that the digital divide persists across all three levels among university students in Malaysia. The path analysis lends support to all proposed hypotheses, with the exception of digital usage as a predictor of student satisfaction and as a mediator.","PeriodicalId":501489,"journal":{"name":"Libri","volume":"134 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141376969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study explores the innovative application of TPRs, such as Double, Ohmni and Temi, within library settings. The findings of the research reveal a positive perception of TPRs, emphasising their potential for fostering innovation, increasing engagement, providing flexibility and overcoming geographical constraints. The study also identifies distinct advantages of TPRs, including remote accessibility, enhanced communication, flexibility, a personalised user experience and cost savings. However, concurrent challenges, such as limitations in nonverbal communication, pointing accuracy, connectivity issues, space requirements, costs, safety, security concerns and varying levels of user acceptance emerge as crucial areas for refinement. While the results may not be generalisable due to the limited sample size, the study underscores the transformative potential of TPRs in libraries and the necessity of addressing these challenges to optimise their application. Further research, technological advancements and user feedback can help refine and optimise the use of TPRs in libraries to provide innovative and accessible assistance.","PeriodicalId":501489,"journal":{"name":"Libri","volume":"113 43","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141126485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
