Research on Digital Preservation: An empirical analysis

Digital preservation is an evolving area of research for libraries, archives, and museums across the globe over the last two decades. Due to the growing recognition of the need to address various issues dealt with digital preservation, this field of study has generated quite a range of scholarly communications on several aspects. The present paper aims to examine critically the extant literature on digital preservation and libraries for the period from 2001 to 2019 and to assess the evolving trajectory and trends. Out of a total of 1292 extracted records from the Scopus database, a total of 710 articles are considered for the study purpose after the exclusion of non-relevant articles. Employing bibliometric indicators the study primarily assessed the publication pattern, document types, the most prolific authors, most contributing institutions, and focus areas of study as well as the geographical distribution of publications. Along with this, the VOSviewer software is used for co-author network analysis. The findings of the current analysis reveal that the highest number of papers published in the source journal Lecture Notes in Computer Science while the U.S.A. is in the top spot among the countries and author Nelson, M. L. from the U.S.A. has published the maximum number of research papers. It also provides information on various forms of publication on digital preservation and the impactful papers. Though there are studies on the assessment of digital libraries and digital repositories, a bibliometric assessment of literature on digital preservation is a novel attempt. As a metric study, it reflects the relative position of a country, an institution, and a researcher

A bibliometric analysis of research papers related to the Mekong River

In the present study, we preformed a bibliometric analysis of published research papers related to the Mekong River during 1991-2012, based on the Science Citation Index Expended. We investigated nation, institution, authors' research performance, the cited times, impact factor, journals and subject categories of the published papers. CPP was used as an indicator to assess the visibility of an article. The impact of countries, institutions, and authors was assessed by h-index and newly developed indicator TC2012. Results indicated that Vietnam had the most output and the most-frequent partners, next is Japan. The authors with high contribution were mainly from Japan. The most three active research fields in the Mekong River were environmental sciences, water resources and geoscience. The top five productive institutions were Chinese Acad Sci., Can Tho Univ., Cantho Univ., Yunnan Univ. and National Univ., while the top five institutions with high h-index were Chinese Acad Sci., Can Tho Univ., National University Singapore, Nong Lam Univ. and International Rice Research Insti. In addition, analysis of keywords was applied to reveal research interests which probably indicated a wide disparity in research focuses
