  In our study we analysed 3.889 records which were indexed in the Library and
Information Science Abstracts (LISA) database in the research field of
informetrics. We can show the core journals of the field via a Bradford (power
law) distribution and corroborate on the basis of the restricted LISA data set
that it was the appropriate time to found a new specialized journal dedicated
to informetrics. According to Bradford's Law of scattering (pure quantitative
calculation), Egghe's Journal of Informetrics (JOI) first issue to appear in
2007, comes most probable at the right time.
