    The purpose of the study is to examine the status of scholarly literature on Corona virus indexed in the big database, the Lens, taking into account, top-cited articles, top contributors, top active country region, most accepted study field and open access status. Relative growth rate (RGR) and Doubling time (Dt) calculation is also a major reflects of the paper. The study analyzes the status of scholarly publications on Corona virus research as indexed by Lens spanning a period from the oldest record until July 15, 2020. “Structured Search” was made under “New Scholar Search” using the term “Corona virus” and restrict the search result only for “Journal Article”. Results obtained were imported through email (.csv file) for further analysis and visualization using spreadsheet software. The results of the study show that out of total 26628 scholarly outputs 2109 are cited in a patent while 15963 in another scholarly literature. “The University of Hong Kong” is the most productive university with 412 scholarly literature, “The United States” as a most contributing country provides 8433 publications, “Journal of Virology” is the most contributing journal with 1012 publications, “Kwok-Yung Yuen” contributed maximum as an individual author and “Elsevier” as a top journal publisher. Among the Lens indexed scholarly publications on Corona virus, 64.04% obtained open accessibility in terms of open access colour while 64.09% under an open-access. No previous study could be identified dealing with such meta-analysis using the Lens database

    Bibliometrics is the discipline where quantitative methods were employed to probe the scientific communication process by measuring and analyzing various aspects of written documents. It helps to monitor the growth of literature and patterns of research. The present paper is based on the analysis of IP Indian Journal of Library Science and Information Technology (IJLSIT) with the help of bibliometrics parameters during the period 2016 to 2020. Among the several bibliometric parameters, the study utilizes mainly the number of articles per volume or year, authorship pattern, collaborative pattern, topmost authors, state-, designation-& affiliation-wise contribution, reference per article count, cited resources type, research trends and research interests. The research data of this study collected manually, analysed with the help of an MS Excel spreadsheet and distinguished according to different types of bibliometric elements. The findings of the study suggested that in IJLSIT, the maximum number of articles published in the year 2019 (25.74%), 53.47% (54) articles contributed by a single author, and the overall collaboration rate is 0.47. Furthermore, 90% (91) of articles contributed by Indian authors and Hemantha Kumar G.H. is the most productive author. Maharastra (18.81%) being the most contributed Indian state, Benue State University & Rayalaseema University (4.95%) being the most contributed institutions and College Librarians are the most designated contributors (20.79%). The study further revealed that 0-5 pages are the most common length, 6-10 references are the most common references used per article, and periodicals are the most commonly cited reference types. The area "Digital Library" is nurtured most among researchers, whereas, the year 2018, vol. 3, issue 1 consists of the maximum views number (18.01%) and the year 2020, vol. 5, issue 1 has the most number of downloads (22.92%).</p

    Open Access Indian Publications: An Empirical Study of DOAJ

    There are two general strategies for achieving Open Access (OA) to scholarly communication, the gold road and the green road. The largest and authoritative gold road OA database is the Directory of Open Access Journals (DOAJ) indexing all the standard OA journals meeting the DOAJ criteria of inclusion. The purpose of this paper is to investigate the contribution of Indian publications to the global OA movement. The analysis of the present study was done based on a total dataset of 289 research publications of Indian OA journal as imported from the DOAJ database. The findings of the study reveal that Indian OA journals account for only 2% of the total coverage of DOAJ. Among them, journals in the field of Medicine alone account for 79% and approximately 73% of journals are published in both print & electronic medium with PDF as the preferred file format, DOI as preferred permanent article identifier and English as the preferred language of publication. Almost 89% of Indian OA journals provide full-text crawl permission, while 75% of them provide download statistics. All the Indian journals covered under DOAJ are peer-reviewed and out of them, most of the journals (76%) are double-blind peer-reviewed. Indian OA publications with CC BY-NC-SA license cover the highest percentage (75%) and 206 journals (71%) do not charge APC. In majority of Indian OA journals (89%), the author doesn’t hold either the copyright or publishing rights without restrictions from the journal publishers. It is important to note that only two journals (~1%) satisfied the requirements of DOAJ Seal
