Introduction
Background
The Library and Information Science (LIS) field, characterized by its focus on developing, organizing, and accessing information held in libraries and archives, has advanced fully. 1 With the advent of digital technologies, there is an increasing need to understand the relationship between traditional library practices and emerging digital tools.2,3 The progression of this discipline makes it essential to stay current with the latest developments to provide optimal library and information services.4,5 The dynamics of professional librarianship and the creation of new knowledge highlight the underlying importance of research within the LIS domain. 6 Consequently, it is to investigate the research performance in LIS to identify areas of strength and weakness, thereby informing its future course. 7 Bibliometric analysis studies, which examine research output and implications across various dimensions, are valuable tools for understanding trends in digital libraries. 8
Several prior studies have explored the evolution of digital library research using bibliometric approaches. 9 Notably, Yaseen et al. 10 conducted an early bibliometric study that analyzed digital library literature published between 1992 and 2004, providing foundational insights into the research field at that time. Their study helped establish key thematic areas in digital library research, such as information retrieval, access models, and user experience. 11 This current study builds upon these earlier bibliometric efforts by providing a more recent analysis (2019-2025) that captures emerging trends, particularly the growing role of Artificial Intelligence (AI), smart library technologies, and interdisciplinary collaborations in digital library services. 12 The increasing dependence of academic research on digital platforms has made digital library services a central infrastructure for knowledge production, positioning their innovativeness and perceived value as critical determinants of research productivity.
The integration of digital library services within academic institutions has transformed information accessibility, particularly in the context of higher education. 13 These libraries use advanced technonlogical infrastructure, such as servers, software, and high-speed internet, to manage and deliver digital content to users efficiently. 14 By employing sophisticated search tools and user-friendly interfaces, digital libraries allow researchers to quickly locate and retrieve relevant information from anywhere. 15 Moreover, digital libraries often incorporate features such as personalized user accounts, citation tools, and interactive platforms for collaborative research, enhancing the overall user experience. 16 This integration improves the efficiency of research activities and supports the continuous evolution of academic knowledge. 17 Similar technological applications have also been reported in public, national, and special libraries, where artificial intelligence and digital systems have been used to enhance user services, collection management, and information access, as documented in previous studies.
In Saudi Arabia, developing digital libraries is a pivotal component of Vision 2030. 18 This strategic plan aims to diversify the economy, reduce dependence on oil revenues, and elevate the country’s educational standards, making Saudi Arabia a global knowledge hub. 19 The vision emphasizes digital transformation, including technology in public services and infrastructure enhancement, to support economic growth. 20 Digital libraries in Saudi Arabia seek to provide researchers with unprecedented access to vast information resources, fostering an environment conducive to innovation and academic excellence. 21
In order to ensure comprehensive and reliable coverage of scholarly output, this study draws data from Scopus, Web of Science, and Google Scholar. These databases were selected because they collectively provide broad disciplinary representation, strong citation indexing standards, and global institutional coverage. Scopus and Web of Science are widely recognized as authoritative citation databases in bibliometric research due to their structured indexing systems, transparent citation tracking mechanisms, and normalized impact indicators. Google Scholar was included to complement these curated databases by capturing additional peer-reviewed conference proceedings and regionally indexed journals that may not be fully represented in commercial indexing systems. The combined use of these three platforms reduces database-specific bias and enhances the robustness of publication trend and thematic analysis.
The analytical component of the study employs VOSviewer for network visualization and thematic clustering. VOSviewer was selected due to its capacity to construct high resolution co-authorship, co-citation, and keyword co-occurrence maps using normalized similarity measures. Compared with alternative bibliometric tools such as CiteSpace or Gephi, VOSviewer offers clearer graphical representation, efficient handling of medium sized datasets, and integrated clustering algorithms that are particularly suitable for identifying thematic structures in focused research domains. Its compatibility with Scopus and Web of Science export formats further supports methodological consistency and reproducibility.
Motivation
Despite their potential, a need remains to understand how users perceive these services, particularly regarding innovativeness and value. 22 Perceived innovativeness refers to the extent to which users believe that digital library services are advanced, cutting-edge, and capable of meeting their evolving needs. 23 This perception is crucial as it directly influences user satisfaction, engagement, and the likelihood of continued use. 24 As it is, perceived value includes users’ assessments of the benefits they derive from these services’ relative to the effort and cost involved in their utilization. 25 A high perceived value is essential for encouraging widespread adoption and effective use of digital library services. 26
Various researchers have noted the issues and prospects implicated by digital library services with specific reference to Saudi Arabia. For instance, Onunka et al. 27 point out that while digital libraries have completely improved access to information, issues such as technological infrastructure, user training, and the relevance of available resources still pose significant challenges. 27 These challenges can impede the effectiveness of digital library services and academic research productivity. 28 Enhancing the user experience is fundamental to making sure digital libraries are perceived as innovative and valuable. 11 Addressing these challenges requires a multifaceted approach considering various factors influencing user perceptions and experiences. 29
The effectiveness of digital library services is shaped by numerous elements, including technological advancements, user interface design, relevant resources, and user support services. 30 Understanding these factors is vital for improving digital libraries to meet academic researchers’ needs. 31 This research aims to provide actionable insights to help develop more effective and user-centered digital library systems by analyzing how these elements affect digital library services perceived innovativeness and value. 16 Such enhancements are expected to align with the broader goals of Vision 2030, contributing to a more dynamic academic research environment in Saudi Arabia. 32
Research problem
Existing challenges, such as inadequate technological infrastructure, insufficient user training, 33 and irrelevance of available resources, can completely diminish digital libraries’ perceived value and innovativeness. 34 While previous bibliometric studies have examined trends in digital library services, they have primarily focused on earlier periods, often emphasizing research outputs before the widespread adoption of AI, smart library technologies, and personalized digital tools. 35 These studies, while valuable, do not provide an up-to-date picture of the rapid advancements shaping digital libraries from 2019 to 2025.
The present research study aims to fill this gap by conducting a focused bibliometric analysis of recent scholarly literature, mapping the evolving research field, and identifying key thematic shifts in digital library services. This research provides a more nuanced understanding of how AI-driven search engines, intelligent recommendation systems, and automated metadata management have transformed digital libraries, improving accessibility, efficiency, and user engagement. Furthermore, by examining regional research contributions, this study highlights the leading nations and institutions driving innovation in this field, particularly in emerging economies such as Pakistan, India, Nigeria, and Saudi Arabia. These insights are crucial for understanding the global diffusion of digital library technologies and the role of collaborative research networks in shaping best practices.
Another key contribution of this study is its focus on the perceived innovativeness and value of digital library services. Unlike previous bibliometric analyses that primarily quantified publication trends and citation performance, this research extends the discussion to include user perspectives, institutional adoption, and the role of digital libraries in supporting academic productivity. By addressing challenges such as inadequate technological infrastructure, insufficient user training, and the relevance of available resources, this study offers both theoretical insights and practical recommendations that can guide digital library development in higher education institutions and research organizations worldwide.

39
The inclusion of these three databases ensured disciplinary diversity and broad geographic representation, strengthening the analytical foundation of the bibliometric dataset. • A conceptual framework is adopted to structure the bibliometric analysis, focusing on three core dimensions: • Research Output Analysis: Assessing the volume and growth rate of publications in digital library services (2019-2025). • Citation Impact Assessment: Evaluating FWCI, h-index, and total citation counts to determine research influence. • Thematic and Regional Distribution: Identifying dominant themes, geographic contributions, and collaboration networks to highlight influential research clusters.
The choice of the 2019-2025 timeframe is motivated by recent technological advancements in AI-driven digital libraries, smart retrieval systems, and automated metadata generation, which have reshaped digital library research. Scopus, Web of Science, and Google Scholar were selected as data sources due to their extensive coverage, citation tracking capabilities, and bibliometric indexing standards. However, database limitations, such as language bias, self-citation issues, and variations in indexing policies, were considered to ensure a balanced dataset.
Data collection
Data sources and selection
The bibliometric data was sourced from three primary academic databases: Web of Science, Scopus, and Google Scholar. However, citation-based impact indicators, such as Field-Weighted Citation Impact (FWCI) were applied exclusively to Scopus-indexed documents to maintain methodological accuracy. Google Scholar was included only for publication volume and thematic analysis, not for citation-based evaluations.
Justification for database selection
Web of Science (WoS): A well-established curated citation index known for its high-quality peer-reviewed content. It was included to analyze citation impact and scholarly influence using standard bibliometric indicators such as h-index and FWCI. Scopus: Offers broader journal and conference coverage than WoS, especially for technology and library sciences research. It was used to assess publication trends, author contributions, and research collaboration networks. Google Scholar: While not a citation index like WoS or Scopus, Google Scholar indexes a wide range of scholarly outputs, including preprints, conference papers, and non-traditional sources. It was included to capture a more comprehensive view of digital library research, particularly for studies not indexed in commercial databases.
Limitations and comparability considerations
The inclusion of Google Scholar posed a methodological challenge due to its different indexing policies, self-citation handling, and lack of standardized citation metrics. To maintain comparability and reliability in citation analysis, only Scopus and WoS were used for citation-based evaluations, while Google Scholar was primarily utilized for publication volume and thematic analysis. By integrating multiple databases while restricting citation-based indicators to Scopus and Web of Science, the study achieved both methodological rigor and dataset diversity, reducing database-specific bias.
Keywords were extracted from author keywords and index keywords of publications indexed in Scopus and Web of Science.
Database-specific adaptations
To ensure consistency and accuracy in the bibliometric analysis, the search strategy was adapted to align with the unique characteristics of each database. Scopus employs structured indexing, allowing searches to be refined using the TITLE-ABS-KEY field restriction, making sure that results were limited to relevant subject areas within digital library research.
WoS, on the other hand, uses a different indexing system; therefore, Topic Search (TS) was applied to focus the search on LIS categories, confirming that only research pertinent to digital library services was retrieved. Google Scholar, being a broader academic search engine rather than a curated citation index, posed additional challenges due to its inclusion of grey literature, preprints, and non-peer-reviewed materials. To address this, a manual screening process was employed to filter out non-peer-reviewed sources and ensure that only scholarly journal articles and conference papers were included in the final dataset. This database-specific approach enabled a balanced, comprehensive, and methodologically sound bibliometric dataset while acknowledging the structural differences in indexing and citation policies across the three sources.
Inclusion and exclusion criteria
A well-defined set of inclusion and exclusion criteria was applied to maintain the integrity of the bibliometric dataset. The study included publications from 2019 to 2025 that explicitly focused on digital library services, confirming that only recent research trends were considered. To enhance reliability, only peer-reviewed journal articles and conference papers were included in the dataset, eliminating any non-peer-reviewed content that might lack academic rigor. Furthermore, articles indexed in Scopus, Web of Science, or Google Scholar with at least one citation were prioritized, as citation count serves as an indicator of scholarly relevance and impact.
Conversely, certain documents were excluded to maintain methodological consistency. Non-English publications were omitted to ensure linguistic uniformity in bibliometric analysis. Books, dissertations, and grey literature were also excluded, as their inclusion could introduce inconsistencies in citation analysis, given that citation tracking mechanisms vary across different publication types. Finally, any paper that did not directly contribute to discussions on digital library innovation, technological advancements in library services, or research productivity in digital libraries was removed from the dataset. By enforcing these inclusion and exclusion criteria, the study ensured a high-quality, thematically relevant, and citation-validated dataset that effectively represents the current state of research in digital library services.
Search execution and data cleaning
To ensure that the study captured the most recent and relevant scholarly outputs, all searches were conducted on January 15, 2025. The retrieved results were then exported in RIS format and processed using VOSviewer and Biblioshiny, two widely recognized bibliometric tools used for network visualization and citation analysis. VOSviewer was specifically chosen because it applies association strength normalization and clustering techniques that allow precise detection of thematic relationships and collaboration patterns. Its visualization clarity and stability in handling citation networks make it particularly appropriate for structured bibliometric investigations within specialized research fields such as digital library services.
Selection criteria identified a final dataset of 88 high-impact publications for detailed analysis.

Document identification and screening procedure
To enhance methodological transparency and reproducibility, the document selection process followed a structured multi stage filtering procedure aligned with PRISMA guidelines. In the first stage, an initial search was conducted across Scopus, Web of Science, and Google Scholar using predefined keyword combinations. This stage yielded a broad pool of records capturing publications related to digital library services, perceived innovativeness, value, and research productivity within the 2019 to 2025 timeframe.
In the second stage, duplicate records were identified and removed through cross-database comparison of titles, authors, publication years, and digital object identifiers. Since several publications were indexed in more than one database, careful metadata verification ensured that each study was counted only once. After duplicate removal, the dataset was subjected to preliminary screening based on title and abstract relevance.
The third stage involved the application of predefined inclusion and exclusion criteria. Publications were retained only if they were peer-reviewed journal articles or conference proceedings written in English and explicitly focused on digital library services and their relationship to technological advancement, user perception, or research productivity. Grey literature, book chapters, dissertations, non-English publications, and studies unrelated to the core theme were excluded at this stage.
In the fourth stage, a citation-based eligibility assessment was conducted. Only publications with measurable citation impact were retained, and for Scopus-indexed records, FWCI values greater than 1.0 were prioritized to ensure above average field normalized influence. This stage refined the dataset to high-impact contributions aligned with the study’s analytical focus.
After completing all filtering stages, a final dataset of 88 publications was confirmed for detailed bibliometric analysis. The PRISMA-style flowchart presented in Figure 1 visually summarizes each stage of identification, screening, eligibility assessment, and final inclusion.
The final dataset of 88 publications included in the bibliometric analysis is fully reflected in the References section of this manuscript. The full list of these records can be made available upon reasonable request by contacting the corresponding author via email.
Data analysis
This study employs FWCI and JIF as key bibliometric indicators to assess the scholarly influence of publications on digital library services. Since FWCI is a Scopus-specific metric, it was applied only to Scopus-indexed documents, making sure consistent and accurate citation normalization across subject areas. Google Scholar documents were excluded from FWCI calculations due to the lack of standardized citation tracking in that database. Additionally, the JIF was considered as an indicator of journal prestige, providing insights into the quality of sources in which digital library research is published. However, JIF is limited to WoS-indexed journals, making it less comprehensive for assessing the overall impact of digital library publications. To address this limitation, we acknowledge that CiteScore (Scopus) could provide a broader perspective since it includes a wider range of journals and conference proceedings. Future research may consider incorporating CiteScore alongside JIF to ensure a more comprehensive assessment of Journal Impact Factor (JIF). Global trends were inferred by comparing longitudinal publication and citation patterns across databases and regions, rather than relying on external global indicators, ensuring consistency with bibliometric practice.
Selection and limitations of citation indicators
• FWCI: Used to normalize citation counts across different research fields, making sure comparability. Applied only to Scopus-indexed documents. • JIF: Measures journal prestige but is limited to Web of Science-indexed journals. Recognized as a traditional impact metric but may exclude important sources from LIS and technology fields. • CiteScore (Future Consideration): Covers a broader range of journals and conferences in Scopus, making it a stronger alternative to JIF for evaluating digital library research impact.
By distinguishing between citation-based metrics FWCI and journal prestige indicators (JIF and CiteScore), this study ensures that bibliometric indicators are used appropriately, taking into account their objectives and limitations. A total of 88 high-impact publications were selected after screening for relevance, peer review status, and citation count. Previous bibliometric studies have demonstrated that robust and meaningful analyses can be conducted with datasets comprising fewer than 100 documents, particularly when the research scope is focused and the analysis is supported by normalized citation indicators. While bibliometric analyses are often applied to larger datasets,40,41 they can also yield valuable insights in smaller scale studies, provided the dataset is carefully curated, thematically focused, and citation-driven.42,43 Previous studies have used bibliometric techniques with datasets of less than 100 documents when analyzing specialized research topics (e.g., niche areas of library sciences or emerging trends in digital innovation). Given the specificity of this study’s research scope, perceived innovativeness and value of digital library services the dataset size remains sufficient for mapping citation impact, thematic trends, and collaboration networks. One limitation of this study is the relatively small dataset (88 documents) used for bibliometric analysis. While previous research suggests that bibliometric methods are best suited for larger datasets (several hundred documents or more), we ensured methodological rigor by selecting highly relevant, high-impact publications and applying standardized citation analysis techniques (Scopus-based FWCI). Future research should expand the dataset to further validate trends and ensure broader generalizability, potentially integrating additional sources or a longitudinal approach over a longer timeframe.
Results and analysis
The Results section is structured in alignment with the study’s research questions, progressing from publication trends and citation performance to regional research output, collaboration patterns, and citation impact, followed by thematic interpretation.
Thematic interpretation of highly cited literature
The theme in the subsection is the impact of user interface design on the perceived value of digital library services.44,45 Users frequently highlight the importance of intuitive navigation, advanced search functionalities, and personalized user accounts as key features that enhance their overall experience. 46 Effective user interface design allows researchers to quickly locate and access relevant resources, which is a significant determinant of the perceived value of digital library services.47,48 On the other hand, poorly designed interfaces can lead to frustration and reduced usage, emphasizing the need for libraries to invest in user-centric design principles. 49 For example, an academic researcher might appreciate a digital library service that allows for seamless navigation between different types of resources and provides tools for organizing and managing these resources efficiently.50,51 This ease of use directly contributes to user satisfaction. It encourages continued use of the service, highlighting the importance of user interface design in the overall perceived value of digital libraries.52,53 The diversity of the dataset enables a comprehensive assessment of publication trends, citation impact, and regional research performance across the global LIS landscape.

Discussion
This study aimed to investigate the perceived innovativeness and value of digital library services and their impact on academic research productivity between 2019 and 2025. 1 By analyzing citation-based indicators across a diverse and internationally representative dataset. The findings confirm that researchers now expect digital services to offer intelligent search functionalities, responsive design, and personalized user experiences. These observations are consistent with recent literature that emphasizes the role of adaptive library interfaces and smart infrastructure in supporting academic engagement.59,63,94 Our qualitative analysis highlights the influence of user experience factors such as navigation design, content discoverability, and platform stability. These dimensions were repeatedly cited by users as central to perceived value. Recent studies also support this claim; for instance, Shahzad and Khan 46 identified semantic digital libraries as more likely to support ongoing academic use when the interface is both intuitive and technically robust. Moreover, the importance of user feedback in shaping service design aligns with the iterative model of digital platform improvement discussed by Wagwu et al. and Xie et al.91,92 This suggests that responsiveness to user input is now a baseline expectation, not a supplementary feature.
The bibliometric results show a clear rise in scholarly output from regions like Pakistan, India, Nigeria, and Saudi Arabia. This pattern corresponds with broader investment trends in research infrastructure across these countries and supports findings by Hasan et al. and Michalek and O’Brien,95,96 who argue that targeted national initiatives play a crucial role in improving both access and research output, such as the increasing FWCI values for these regions indicate that their contributions are not only frequent but also increasingly influential. Compared to the fragmented global contributions observed in earlier periods, this shift demonstrates a decentralization of research excellence in digital library studies. 97
Finally, the co-authorship and collaboration analysis reveals limited but emerging regional partnerships. 98 The presence of multiple sub-networks without strong interconnections aligns with the conclusions of Mathiasson and Jochumsen who note that digital library research often remains institutionally or regionally siloed. Bridging these silos through interdisciplinary and international cooperation could improve thematic diversity and knowledge transfer across contexts. 99 Our results emphasize that while the tools and technologies are in place, more structured collaboration strategies are necessary to maximize global research productivity and technological adaptation in digital libraries. 100 Future research may further extend this analysis by incorporating co-word analysis to provide deeper insights into thematic structures and the evolution of research topics in digital library services. In developing regions, where traditional library infrastructures are often less established, additional challenges such as limited connectivity, resource constraints, and uneven digital literacy may further affect access to and effective use of digital library services.
