The significance of this research lies in its contribution to understanding the dynamic landscape of literacy studies within library contexts, offering valuable insights for future research and practical applications in the field.


INTRODUCTION
Literacy involves the ability to read, write, speak, and listen effectively, enabling individuals to communicate with the world.A lack of essential literacy skills can hinder a person's progress at every stage of life. [1]Over time, different literacy skills have evolved, with the concept of an information-based society emerging in the 1950s after World War II. [2]The term 'information society' was coined by economist Fritz Machlup. [3]Since then, information has played a crucial role in economic and cultural activities in terms of creation, distribution, and manipulation.However, with the continuous growth of information, concerns about misinformation and disinformation have also risen, such as fake news, propaganda, clickbait, hoaxes, and rumours.To address these issues, individuals need to adopt various literacy programs, and library and information science professionals can play a vital role in providing guidance.Libraries and professionals have resorted to various literacy methods to prevent misinformation, including library instructions, user and library orientation, OPAC instruction, information literacy instruction, media literacy, digital literacy instruction, and more.Studies have been conducted to analyse and explore the roles of libraries and professionals in promoting literacy among user communities.This study attempts to conduct a bibliometric analysis using a variety of statistical models to recognize the state of literature and explore the structure of knowledge, assuming that "data speak for themselves". [4,5]

LITERATURE REVIEW
Despite the brief history of bibliometric studies on literacy in the Library and Information Science field, they have been conducted for several reasons, including: In their bibliometric study, Pinto et al. [6] used statistical, mathematical, and content analyses to investigate international scientific productivity in Information Literacy (IL) literature published between 1974 and 2011, as indexed in the Web of Science (WoS) and Scopus databases.The authors extracted results about authors' productivity, distribution of disciplines, co-authorship, affiliations, and frequently used journals.The study's findings showed continuous growth in literature and the prevalence of Anglo-Saxon authors.The authors' affiliation demonstrated significant dispersion, and the study confirmed the fit of Lotka's law and Bradford's law.To investigate research trends on IL, Shaheen et al. [7] conducted a bibliometric study on the data published between 2003 to 2012 in the Scopus database.The study examined the annual growth rate of preferred journals for article publication, authors' productivity, countries' contribution, and subject-wise distribution of publications.Analysis of the data revealed a steady increase in literature over the past decade, with authors from North America and the United Kingdom showing higher productivity compared to other countries.A similar study was also conducted by Shankar Reddy Kolle [8] in a publication related to information literacy literature between 2005 and 2014.The study found that annual growth was higher in 2007, 2008, and 2011.The most productive author and institute were identified as "Pinto, M. " and the "University of Granada, Spain, " respectively.The "Journal of Academic Librarianship" was the most commonly preferred.The study also found that the contribution of the USA was high.The research topics of "digital divide, " "media literacy, " "pedagogy, " "higher education, " and "critical thinking" were identified as prominent in the field of Information Literacy.In the study by Parlina, Ramli, and Murfi, [9] a decade of big data research (2009-2018) is scrutinized using bibliometrics and text mining.Results reveal a surge in publications since 2014.Core journals, prolific authors, and influential entities are identified.A unique thematic analysis uncovers dominant themes, with big data analytics standing out, covering methods, tools, infrastructure, and applications.Security, privacy, social networks, and the Internet of Things emerge as critical aspects.To assess the scientific productivity of mobile IL literature in higher education Pinto et al. [10] conducted a bibliometric study.The study analysed papers covered by Library and Information Science Abstracts (LISA), Library and Information Science and Technology Abstracts (LISTA), Web of Science (WoS), Scopus, and Education Resources Information Centre (ERIC) published between 2006 and 2017.The study's findings provided an overview of mobile information literacy and identified the most relevant journals, average authors' productivity, productive authors, and research trends in this field.To analyse the evaluation of IL in literature indexed by the Scopus database between 1975 and 2018, Omwoyo [11] conducted a bibliometric.The study showed that the concept of IL has expanded beyond the field of social science and into various disciplines.It also revealed the emergence of different types of literacy such as content literacy, media literacy, health literacy, metaliteracy, and business-related literacy after 2000.Additionally, the paper proposed a collaborative and multidisciplinary approach to research activities in the field of IL.Apart from all these traditional studies, with a modern approach, Li et al. [12] conducted a study using topic modelling to evaluate subject characteristics of IL topics published between 2005 and 2019.Latent Dirichlet Allocation (LDA), introduced by Blei et al. [13] in 2003, serves as the foundation for topic modelling in this study.LDA operates as a probabilistic model, representing each document within a corpus as a random mixture across latent topics.These latent topics, in turn, are defined by distributions over words, encapsulating the probabilistic relationships between documents and the underlying thematic content.The study found that core topic words remained relatively stable, while also identifying new research directions published in recent years.
Based on the above discussion, it is evident that numerous studies have already been conducted, particularly in the field of IL, to identify the productivity of authors, institutions, countries, and keyword frequencies.However, this area of study has not adequately explored the utilization of topic modelling techniques to gain insights into library-related aspects within the context of Information Literacy.Furthermore, comprehensive studies that delve into historical developments and focal points in literacy within library settings are noticeably lacking.The study aims to fill this gap by providing a holistic analysis of the literature from 1969 to 2021, shedding light on the knowledge and research trends in this specific area.Specifically, the study seeks to answer: How has scholarly productivity evolved in the field of literacy in libraries during the specified period?What is the knowledge structure within this field, and how do different research themes relate to each other?

Objectives of the study
This study aims to assess the academic literature on literacy that was implemented in libraries from 1969 to 2021.To achieve this goal, the study has the following objectives: To assess the scholarly productivity and evolution of literacy in library research during these 52 years through a bibliometric analysis.
To reveal the knowledge structure within this field, utilizing probabilistic topic modelling.

METHODOLOGY
In a nutshell, our methodology blends bibliometrics and probabilistic topic modelling to gain insights into the academic literature on library-based literacy over the specified time frame.

Data source
To conduct our analysis, we utilized a bibliographic dataset, extracted from the SCOPUS database that spans from 1969 to 2021.We chose this database due to its comprehensive features, widespread usage as one of the leading bibliographic databases, and its inclusion of only peer-reviewed publications.

Data inclusion criteria
To narrow down our focus on literacy in the library context, we conducted an advanced search using specific queries (mentioned in the textbox below) in the SCOPUS database, resulting in the retrieval of 4986 relevant documents.TITLE-ABS-KEY ("literac*" AND "librar*") AND PUBYEAR > 1968 AND PUBYEAR < 2022 AND (LIMIT-TO (DOCTYPE, "ar")) AND (LIMIT-TO (LANGUAGE, "English"))

Data summary
On December 31 st , 2022, we extracted the bibliographic data, for this study.We restricted our bibliographic dataset to include only sources published in the article format and written in the English language from 1969 to 2021.

Bibliometric analysis
To assess the status of the literature based on the bibliographic data (such as authors, journals, countries, and author keywords) of the retrieved documents, we employed the bibliometrix package of R, a statistical computing language. [14]Biblioshiny, Java software, was created by Massimo Aria at the University of Naples Federico.It seamlessly merges the capabilities of the bibliometrix package with the user-friendly interface of web applications. [15,16]escriptive statistics were used to evaluate the productivity of authors, journal sources, and countries, as well as the occurrence of keywords related to the themes of the studies in this field.
The keywords used in the articles can provide an accurate explanation of the topics covered.Therefore, analyzing the networks of keyword co-occurrence can reveal the connections among the topics covered in the articles.Implementing this method helped to identify the research themes and establish relationships among them.

Probabilistic topic modelling
Additionally, to reveal the underlying structure of knowledge from the titles, author's keywords, and abstracts of the documents in the field of interest, we utilized a probabilistic topic model called Latent Dirichlet Allocation (LDA).LDA is a technique that enables automatic topic mining by identifying clusters of word co-occurrences to uncover hidden topics or thematic structures within documents. [12,13]In this model, documents are viewed as a combination of topics and these topics are viewed as a combination of words.These topics generate words through probability distributions.Documents are therefore considered as a distribution of topics and topics are considered as a distribution of words.This model is advantageous due to its exchangeability of words and documents among the topics, leading to improvement.The LDA model is performed in two phases.In the first phase, the distribution of topics is arbitrarily selected.In the second phase, for each word in the documents, a topic is randomly assigned from the distribution of topics. [17,18]This model can be expressed mathematically as follows, A set of documents was prepared for analysis with the LDA model by combining the corresponding articles' titles, abstracts, and authors' keywords.Articles without abstracts were removed.Additionally, the documents underwent several cleaning and processing steps, such as lowercasing, tokenization, removing stop words, normalizing words, erasing punctuation, and removing short words.The 'Text Analytics Toolbox' of MATLAB 2018 software was used to perform these steps. [19]

Limitation
The dataset extracted for this study from the Scopus database, which is comprehensive, but may not capture all pertinent articles and could be subject to inclusion and coverage biases.It purely concentrates on English-written articles, potentially introducing language bias by omitting crucial research conducted in other languages.Given its bibliometric nature, the study might not consider other factors such as research impact on practice, societal relevance, etc.

Research trends
Literacy studies in the Library Science domain show notable research trends.The dataset, covering the period from 1969 to 2021, indicates that 8,121 authors contributed to 4,986 publications from 733 distinct sources.The dataset has been growing at an average annual rate of 12.2% (Figure 1).This suggests that the number of documents or sources has been increasing steadily over the years.On average, each document in the dataset has been cited 12.03 times.This is a measure of the impact or influence of the documents.On average, each document is cited once per year.This is another way of assessing the frequency of citations.There are a total of 7,600 author-generated keywords associated with the documents.These keywords are often used to describe the main topics or themes of the research.8,121 unique authors have contributed to the documents in the dataset.Out of the total authors, 1,660 have authored documents on their own without co-authors.There are 2,048 documents in the dataset that have been authored by a single author without collaboration.On average, each document has 2.11 co-authors.This indicates that most documents are the result of collaboration between multiple authors.
Aparicio et al. [20] proposed that each scientific production undergoes three stages of growth.Using their framework, we identified that during the initial stage (1969-1996), an average of 4.5 articles per year were published, resulting in a total of 126 documents.In the development stage (1997-2004), the publication rate increased to 62.25 articles per year, resulting in a total of 498 documents.Finally, in the expansive stage (2005-2021), the publication rate further increased to 256.58 articles per year, resulting in a total of 4362 documents.

Influential authors
Table 1 provides data on the research productivity of various authors, considering the number of articles they have published, the total citations their work has received, the year of their first publication, and their years' contribution to this field as of 2021.This information provides valuable insights into the authors' contributions and impact within their respective domains.
Julien, H., with 28 articles and 562 citations since 1997, appears to be a highly productive and influential researcher, showcasing a consistently impactful track record in the academic community.Despite publishing fewer articles (19), Pinto, M., has accrued a notable 314 citations since 2008, indicating substantial recognition within a relatively short timeframe.Lloyd, A., Gross, M., and Latham, D. exhibit comparable numbers of articles and citations, signifying that their work since 2003 and 2007, respectively, has consistently left an impact on their respective fields.Saunders, L., Spring, H., Ameen, K., and Merga, M.K. all having commenced their research journey in the mid to late 2000s, showcase variability in their article numbers, with their total citation counts reflecting diverse levels of influence within the academic community.Hicks, A., started publishing in 2010 with 10 articles and 39 total citations, and is in the early stages of the research career, with the potential for further growth in impact.

Global Research Productivity and Collaboration
Table 2 provides a comprehensive overview of research productivity and collaboration patterns among countries, considering both the number of articles produced and the citation impact.
In the first part of Table 2, countries were ranked based on the number of articles they produced.The United States, with 1985 articles, is the clear leader, signifying its substantial research output, and is followed by the UK, Canada, Australia, and other countries.It indicates countries' contribution to global research.The Table 2 reveals the percentage of Single-Country Publications (SCP) versus Multiple-Country Publications (MCP) for each country.A higher percentage of SCP suggests a more independent research landscape, while a higher percentage of MCP implies greater international collaboration.In this context, Nigeria, with 2.42% SCP indicates a relatively higher degree of international collaboration, whereas countries like the USA (57.40% SCP) and China (1.85% SCP) show different patterns.The number of MCP reflects the diversity and strength of international research collaborations for each country.For example, the UK has 12 MCP, indicating a moderate level of research collaboration with other nations, while China has 13 MCP, illustrating a growing international presence in research collaborations.Countries like India, Pakistan, and South Africa, with lower overall article counts, show relatively high percentages of MCP.This suggests that these countries are actively engaging in international research collaborations, potentially serving as regional research hubs.
The second part of Table 2, focused on research impact, ranking countries by the number of citations received and the average number of citations per article.While the USA has the highest citation count, its average number of citations per article (11.09) is lower than countries like the UK (12.98) and Australia (15.34).This suggests that the USA's research output is extensive, but individual articles may receive fewer citations on average compared to the UK and Australia.The wide range of average citations per article among countries, from Sweden's 23.35 to Nigeria's 4.74, reflects the variability in research impact and quality.Sweden's high average citation count suggests a strong emphasis on producing highly influential research.This data underscores the importance of considering both the quantity and quality of research output.While high citation counts signify research influence, a high average citation per article implies that a country's research is consistently impactful.

Journals' productivity
Journals' productivity has been assessed through their rankings (Table 3).This ranking of journals is based on their h-index and total citations.The Journal of Academic Librarianship tops the list with an h-index of 35 and 4404 total citations.Reference Services Review follows closely with an h-index of 32 and 4161 citations.College and Research Libraries take 3 rd place with an h-index Health Information and Libraries Journal having more total citations.This ranking highlights the importance of considering both the h-index and total citations when evaluating a journal's impact and significance within a field.

Most globally cited documents
Globally cited literacy research reflects a dynamic and diverse field, addressing digital evolution, social nuances, practical applications, geographic considerations, interdisciplinary collaboration, enduring impact, paediatric literacy, and emerging concepts, collectively contributing to a comprehensive understanding of literacy in our changing world.The rankings of the studies in Table 4 are determined based on the total number of citations received, reflecting their impact on shaping a holistic comprehension of literacy within the evolving global context.

Highly Cited Articles
Articles with higher citation counts, such as "Information and digital literacies: a review of concepts" and "The role of home literacy environment in the development of language ability, " have likely made significant contributions to their respective fields.Higher citation counts may indicate that these articles are influential and have been widely referenced by other researchers.

Diversity of Topics
The articles cover a diverse range of topics, including information literacy, healthcare decision-making, literacy development in children, and digital competence.The variety of topics suggests that these articles address important issues in different domains, reflecting the multidisciplinary nature of research in information science, education, and healthcare.

Temporal Trends
The articles span a range of publication years, from 1994 to 2016.
This indicates that influential articles can emerge at different points in time.It may be interesting to explore whether there are trends or shifts in the topics and methodologies of these articles over the years.

Impact on Practice
Articles like "Critical Information Literacy: Implications for Instructional Practice" may have implications for teaching and practice in academic librarianship."Adopting evidence-based practice in clinical decision making" and "Risk Factors and Screening Instruments" may have influenced healthcare practices and policies.

Potential for Future Research
The Table 4 may guide researchers in identifying key areas of interest based on citation counts and topics with fewer citations.It could be an indicator of gaps or emerging trends in the literature.

Conceptual framework
Figure 2 depicts the co-occurrence network of the top 50 authors' keywords, and the 'Louvain community detection algorithm' [21] was used for this purpose.Based on the algorithm's analysis, three major research themes were identified and are described below.
The theme of information literacy heterogeneity (red) encompasses the various forms of information literacy that are adopted by libraries to educate users on how to deal with the different types of information provided by the library.
The roles of librarians in promoting IL (blue) refer to how professionals in the library and information science field promote literacy within user communities through various teaching and learning methods.
The theme of health literacy and the library (green) involves the promotion of health literacy among library users through various channels, including the Internet, social media, and outreach programs.
The themes were categorized using a thematic map to better understand the structure of the knowledge [4] (Figure 3).Based on their density and centrality, the themes were divided into four sections.The Motor themes, which had higher centrality and density, were found in the upper right quadrant and played a vital role in shaping the conceptual structure of the scientific field.This means they are not only at the core of the knowledge structure but also well-developed and interconnected.

Topic modelling
Performing topic modelling using the LDA technique Figure 4 provides an insightful structure of a given data set (corpus) which is a random mixture of latent topics.However, there is no specific rule for determining the exact number of latent topics.Topic 3 is on examining information literacy skills in graduate and undergraduate students using surveys, tests, and questionnaires.It explores factors impacting skill levels, such as academic orientation and prior behaviours.It informs curriculum design and targeted literacy programs, emphasizing the importance of enhancing students' skills for academic success.

Topic 30 emphasizes the importance of promoting reading and literacy in elementary education.It highlights the role of diverse reading materials, e-books, and classroom activities in motivating students to develop a reading habit.The research also discusses the impact of reading on vocabulary, language, and cultural knowledge, advocating for literacy advocacy programs to empower young learners and improve their overall literacy skills.

DISCUSSION AND IMPLEMENTATION
The descriptive analysis of this study suggests a consistent expansion in literacy research within the framework of library studies, mirroring the trends observed in S.R. Kolle. [8]This study's examination of international scientific collaboration delineates the distinct features of research endeavours across various countries, echoing the findings of Pinto, María and et al. [6] The outcomes of LDA topic modelling yielded an estimation of 32 latent topics within the field of literacy studies related to library research.The diverse array of topics reveals the multifaceted landscape of information literacy.The global significance of information literacy (Topics 1 and 9-16) emphasizes its holistic role beyond education, touching on critical aspects like public libraries, societal development, and digital competence. [23]The integration of information literacy into university curricula (Topics 2 and 17-24) is underscored, with collaboration between students, faculty, and librarians being pivotal. [24]Assessing information literacy skills (Topics 3 and 25-32) emerges as a crucial aspect. [25]The evolving roles of librarians (Topics 5, 13, 16, and 29-31) further contribute to this landscape, recognizing librarians as dynamic contributors in combating fake news, fostering creativity, and championing health literacy. [26] summary, examining research trends, this study employed a combination of bibliometrics and LDA topic modelling.The use of computer algorithms for quantifying and analysing textual data eliminates subjectivity, revealing patterns in texts and aiding researchers in extracting meanings from extensive datasets.

CONCLUSION
In conclusion, the study highlights the evolution of research productivity in the area of literacy, which has gone through initial, development and expansive stages.The emergence of various concepts related to literacy, such as digital literacy, media literacy, health literacy, etc., has led to an increase in research productivity.Authors from Western countries have been found to dominate this field in terms of the total number of articles and citations, frequency of publication, research cooperation, single-country publication, and multiple-country publication.The study also identifies the key research themes and their relationships using thematic maps, which suggest that professional development, health literacy, and library outreach programs are the prominent areas of study.The LDA model analysis helped in grouping the literature into 32 topics, which provides a crystal-clear idea of emerging research areas like digital literacy, social media, and fake news.Overall, this study provides valuable insights into the evolution of research productivity and the trends in literacy-related research.
Assuming we have a set of documents D, where, each of the documents is a square of N words, =( w d,1 , w d,2 ,…, w d,N ) and each word is an item from vocabulary indexed by {1, …, V}.Let there be K latent topics β 1:K , representing the distribution of the vocabulary.Based on this model, the posterior distribution will be Where, θ d = Topic proportions of the d th document, z d = Topic assingments for d th documents, w d = set of observed words.
