The editors of Mathematical Structures in Computer Science have just sent a very strong letter to the EC which has decided to use the citation indices (there are apparently more than one) in a formal way. The American editors seemed to say, that they were used very little for tenure or hiring purposes in the US and, to my knowledge (from tenure decisions at McGill but at least in the early 90s never used by the main granting agencies. But above and beyond that, there was a time when I was actually using the citation index for its stated purpose. It was when I was starting my work on duality and I wanted to know to what extent the Pontrjagin duality had been extended to classes of topological abelian groups larger than that of locally compact groups. Every useful for that, but not if it gratuitously omits certain journals. One of the strongest points made is that the citations often go to derivative works rather than the original. This is not malice on the part of authors; often the derivative source is simply a better, clearer, whatever, source than the original. In a similar way, you cannot judge a mathematician from the number of his students. Gauss had only 8 students, and four of them, including three of the best known (Dedekind, Sopie Germain, and Riemann had exactly none). But he has, in toto, close to 45,000 descendants, over 70% of whom were descendants of someone named Christain Gerling, whom I had never heard of until I just looked it up. My guess is that most of us are descended from Gauss (I am). Gustav Herglotz had 1278 descendants nearly all of whom descend from one student: Emil Artin (my doktorgrandfather). My point is that these things are simply not decent measures of value or influence. The ISI is useful for some things and useless for others, including making this kind of judgment. That's what people are good at.
