Contribution of Indian authors in foreign library and information science journals during 2006-2015 using Library, Information Science and Technology Abstracts database is examined in this study. This scientometrics study analyses the research publication productivity and trend according to year, authorship, most prolific authors, Indian states, institutions, preferred journals for communication and subject. It is found that Indian authors contributed a total number of 234 articles during the covered period and collaborative articles with two-authors are highest in numbers. Library Philosophy and Practice has emerged as the most preferred journal by authors for publication. In terms of keywords/areas of study 'Users' and Study' has emerged as the most preferred research area to publish during the period.

The published articles in leading Indian LIS journals during 2012-2017 have been mapped to depict the authorship pattern and collaboration trend in LIS domain of India. The study assessed the collaborative authorship trend on using different parameters like journal wise pattern, year wise collaboration, co-authorship index, ranked list of most productive authors and the level of collaboration. The Lotka's law on author productivity has also been tested to confirm the applicability of the law to the present data set. It is found that two-authored papers are predominant (48%) in LIS publications and the collaborated articles of multi-authorships received greater average citations. Besides, in Indian LIS discipline, maximum collaboration occurs in intra-institutional level and inter-institutions within state level. Therefore, it is recommended that the LIS schools across the country should also consider interdepartmental collaboration to produce more quality works on emerging and innovative research areas.

The present scientometric study assesses the publication output of the scientists of Indian Association for the Cultivation of Science (IACS) during 2008 to 2017 as reflected in the Web of Science database to figure out the research performance, scholarly communication behaviour and its citation impact. The scientists of IACS contribute total 4,304 research articles including 22.58 percent international collaborated articles. Further, the publications have been evaluated in terms of year, types of collaboration, authorship pattern, source journals, impact factor, collaborating institutions, collaborating countries and citations. It is found that majority of the published articles are produced by three authored and the international collaborated articles which receive wider citation impact. The developed countries like USA, Japan, Germany and England are found as the most favoured countries by the scientists of IACS for research collaboration and the Journal of Physical Chemistry C shares maximum research articles. Further, Pareto’s 80/20 principle has also been applied to examine the scattering of journals as well as articles and the VOS viewer software has been used for mapping the network of collaborating countries.

On the 125th birth anniversary of Professor Prasanta Chandra Mahalanobis, the authors analyse characteristic features, pattern and citation impact of the great Indian scientist and statistician's scientific works. A bibliography of his scientific contributions was prepared. It contained 6 books, 142 journal articles, 87 conference papers and 38 research reports. The study categorizes and presents the data according to year-wise contribution, authorship pattern, collaborators, preferred journals for communication, country-wise publications, top cited authors, citation history and citation impact. The study revealed that his research productivity peaked during 1934 to 1938 at the ages 41-45, with contribution of 77 scientific works. Further, the citation history of top 11 cited papers during 1990-2017 indicates that his publications are still being cited regularly which proves the continued relevance of his theory and applications over time.
