Study of Authorship Pattern, Collaboration and Application of Lotka's Law for Evaluation of Author Productivity in Conference Proceedings of IFLA

The paper examines the authorship pattern and author collaboration in the conference proceedings of World library and Information Congress organised by International Federation of Library Institution and Association (IFLA). For the study, the data from 2011 to 2015(5 years) has been taken. The authorship pattern is studied and the degree of collaboration is calculated which is 0.4463 for the present dataset. In the paper, Lotka's law was tested for which the value of the exponent n and the constant c were computed. Kolmogorov-Smirnov (K-S) goodness-of-fit is applied to verify the applicability of Lotka's law. It is found from the study that observed distribution is different from theoretical distribution predicted by Lotka's law. The law does not fit in the observed distribution of IFLA.
