Impact Factors

Mon Apr 4 08:26:28 EST 1994

The Impact Factor (the number of citations received over two years divided
by the number of citable items published over that same two year period)
is a standard statistic published by the Institute for Scientific Information
in their annual Journal Citation Reports for Science Citation Index (and
Social Science Citation Index).  The JCR is published along with the annual
hardbound cumulated SCI every year, but it is a separate subscription (approx
$195 US) in a combination of print and microfiche.  A top academic library
in Japan should be subscribing. Since bibliometric research is very visible
in Japan, the library associated with a major library science program might
also have it.  If you need one or two numbers, I can look them up for you.
Otherwise, you could contact ISI directly or through their Japanese
representative.  Many of the ISI staff are also on the internet.

Good luck.
