    Abstract
    There exists a direct linear relation between journal production and impact factor. The more articles a 'normal' journal publishes, the larger its impact factor. Review journals and translation journals are clear exceptions to this rule. The field of mathematics and chemistry seem to be large scale exceptions

    Abstract
    The relative impact of local research units is obtained by dividing the observed number of citations to their publications by the expected number of citations. It is argued that the expected citation rates used in the standard method cannot lead to relevant bibliometric scores for specific research topics. Extracting information about quality of research with the standard method is, therefore almost impossible. The existence of empirical relations between the number of citations and the number of publications for scientific disciplines and for journals, leads to alternative ways to determine relative impact. Hereby, refernce data are taken from within a given research topic. Only observed citation and publication (activity) patterns for research topics are taken into account for calculating bibliometric scores. The new methods are not restricted to ISI-publications. The rsulting bibliometric scores can contain information about the quality of research, and lead to different rankings than those obtained with the standard methods, although the same citation and publication data are used
