The impact factor of journals has been widely used as glory quotients. Despite its limitations, this citation metric is widely used to reflect scientific merit and standing in one's field. Apart from the impact factor, other bibliometric indicators are also available but are not as popular among decision makers. These indicators are the immediacy index and cited half-life. The impact factor itself is affected by a wide range of sociological and statistical factors. This paper discusses the limitations of the impact factor with suggestions of how it can be used and how it should not be used. It also discusses how other bibliometric indicators can be used to assess the quality of publications.
