Bibliometric indicators for evaluating the quality of scientifc publications.

Evaluation of quality and quantity of publications can be done using a set of statistical and mathematical indices called bibliometric indicators. Two major categories of indicators are (1) quantitative indicators that measure the research productivity of a researcher and (2) performance indicators that evaluate the quality of publications. Bibliometric indicators are important for both the individual researcher and organizations. They are widely used to compare the performance of the individual researchers, journals and universities. Many of the appointments, promotions and allocation of research funds are based on these indicators. This review article describes some of the currently used bibliometric indicators such as journal impact factor, crown indicator, h-index and it's variants. It is suggested that for comparison of scientific impact and scientific output of researchers due consideration should be given to various factors affecting theses indicators.
