The study examines 1220 digital library research papers published by BRICS countries during the period 2000 to 2019. Bibliographic data on the research papers were collected from Web of Science database. It is found that maximum number of publications (225) were two-authored. The Degree of collaboration is 0.84, collaborative index is 4.14, the collaboration co-efficient is 0.59 and the modified collaboration co-efficient is 0.61. Among all the BRICS countries, China has contributed the most number of papers [690 (56.58%)] followed by India with 205 (16.80%) contributions. Lotka's law was not found to fit with the observed author's productivity of the study. The study concludes that there is increased research on digital library in BRICS countries.

The paper examines authorship pattern of 556 papers published in Journal of Documentation during 2003 to 2015. In addition to the papers, a sample of 1550 references from a population of 15,529 unique references given at the end of the papers were selected using simple random sample method. It was found that almost half of the publications were written by single authors. Lotka's Law was tested on the resulting 2106 publications using Kolmogorov-Smrinov goodness-of-fit. The K-S test and the author productivity graph revealed that Lotka's law was applicable to the set LIS publications. [ABSTRACT FROM AUTHOR]

The study analyses the publication pattern of faculty members of three universities in Kerala viz., University of Kerala, Mahatma Gandhi University and University of Calicut. Authorship pattern, Degree of Collaboration, the appropriateness of Lotka's Inverse Square Law and year-wise and designation-wise distributions have been studied. The year-wise distribution of publications indicates that there is a growth in the number of publications. It is found that multi-authorship dominates among university teachers and there is no statistically significant difference between the experience and productivity. Designation-wise Degree of Collaboration shows that Professors are having a high Degree of Collaboration which indicates that increase in the age and experience results in more collaborative papers. The Lotka's inverse square law seems to be rejected for the present data set.
