  • Impact Factors: Summary

    A while back I posted an article concerning the whereabouts of journal
    impact factors. I have had several requests for information on these,
    so what follows is what I have managed to glean:

    The Impact factors are available from most university libraries, as
    they should have a copy of the "Science Citation Index, Journal
    Citation Reports" from the Institute for Scientific Information. The
    ISI can be contacted on (correct for 1992)

    USA: 215 386 0100
    Europe: +44 (0)1895 270016 (Brunel University)

    In the index there are several indicators of a journals worth,

    the number of articles published in the journal to date.
    no. of times journal was cited.
    no. of articles cited in the year of publication (immediacy index).
    impact factors - average number of current citations to articles in a
    journal over the last two years.
    and other indicators.

    On the issue of the use of impact factors, I have entered into several
    discussions with other Biomech-L members. There is an opinion that you
    have to take care when using these, as obviously a journal publishing
    controversial or flawed papers could have as high an impact factor as a
    journal publishing only very good articles. The best use of them is as
    an indication of the audience that the journal reaches.

    I stated this in my original article, and I re-emphasise it, should the
    ISI be 'listening', surely information like this should be available on
    the WWW.

    Thankyou for your replies to my original posting,
