Is the best measure of a scientist's worth the total number of his or her
published papers? For many years Institute for Scientific Information has
been publishing the lists of impact factors providing quantitative tools
for ranking scientists. The impact factor was devised by Eugene Garfield,
the founder of the Institute for Scientific Information. Impact factors are
calculated each year by the Institute for Scientific Information for those
journals which it indexes, and are published in Journal Citation Reports.
These measures apply only to journals, not individual articles or
individual scientists. For the impact factor of individual scientists,
there exists the h-index or Hirsch number. The Hirsch-index (h-index) has
recently been defined by Hirsch as a new method for measuring the
scientific activity. If a scientist has published n articles which all have
been cited at least n times, then he will have a h-index of n . The h-index
seeks to describe the impact of individual researchers, rather than
journals. The h-index is the result of the balance between the number of
publications and the number of citations per publication. H-index: Impact
of Individual Scientists. H-index or/and impact factor - it is the question
of the future.
