Title: Biobibliometric portrait of the astronomer Jan Hendrik Oort Authors: Koley, Susanta; Sen, B K Abstract: Jan Hendrik Oort is recognized as one of the greatest astronomers of the 20^th century. His 225 publications that appeared during 1922-1992 are analyzed. Most of the papers of the scientist (N= 170) are non-collaborative. Oort’s first paper was published in 1922 at the age of 23. The period 1957-1961, when Oort was 58-62 years old, was his most productive period (nearly 5 papers per year). From the period of 7^th to 13^th quinquennium (age 53-87) he produced nearly 4 to 5 papers per year. In the byline of authors his status ranged from first to third and ninth. Oort’s research team comprised of 67 collaborators. C. A. Muller and G.W. Rougoor were his leading collaborators. Most of his papers were published in journals, mostly emanating from Netherlands (N=71), USA (N=55) and UK (27) etc. The publication concentration is 2.27 and publication density 16.16. The most frequent keywords are Galaxy(ies) (N=23), Galactic System (N=17) and Structure (N=17). Finally, it is seen that the data set does not follow Bradford law. Page(s): 217-228

Title: Availability and accessibility of e-resources in academic libraries in Nigeria: the impact of the interventionist programmes Authors: Umeozor, Susan N.; Emasealu, Helen U. Abstract: The impact of e-resources and the accompanying infrastructural development has not been fully realized in most developing countries necessitating some interventionist programmes. This study was undertaken to assess the impact of donor agencies in interventionist programmes with regards to the availability and accessibility of e-resources in Nigerian Federal University of Ibadan (UI) and Obafemi Awolowo University (OAU). A structured questionnaire was adopted for data collection. A total of 480 lecturers were involved in the study with 240 per institution, 80 from each of the three Faculties per institution and 20 lecturers from each of the four departments per faculty. Frequency counts on availability of e-resources were subjected to Analysis of Variance and Duncan’s Multiple Range Test while frequency counts on accessibility of e-resources were subjected to percentages. Results indicated that AGORA, HINARI and JSTOR were popular and also that the percentage of accessibility of these e-resources was 98.2, 98.2 and 96.4 for the Faculties of Agriculture, Science and Social Sciences, respectively in UI and 100% in each of the three Faculties in OAU. AGORA, HINARI, and JSTOR are members of the interventionist group and being significantly more available than the other resources is a strong indication that the interventionist programmes have had a positive impact on the e-resources users in Nigeria.

Title: Author productivity and the application of Lotka’s Law in LIS publications Authors: Kumar, Suresh P K Abstract: 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. Page(s): 234-241
