Abstract
This paper points out severe limitations of h-index being used extensively for evaluating the scientific research performance through citation analysis. It compares some commonly used indices and finds that among the presently used indices, g-index would appear to be a better indicator as it considers the quality of individual papers measured through number of citations, which h-index ignores. However; g-index is rarely being used to evaluate research performance of authors as it is not very easy to compute due to iterative process involved. To overcome this limitation and further enrich g-index; the author has proposed two indices: P-index called Prime index and V-index called ‘Value added index’ which takes into account the average number of authors / paper published by a particular author. P-index is most easy to compute and gives results which are 2-3% higher than g-index because it includes 100% of citations from an author. The V-index is a novel index of taking into account the average number of authors to normalize the research contribution from an author in multiple authored papers.
