Problems with impact factors computed and published by the ISI?-2

[Juan Miguel Campanario]

Dear people:

Many thanks for your e-mail messages concerning my post on problems
with impact factors.

I did not computed citations. I just used the numbers publised by the ISI
in the
JCR.
Below is an excerpt (copy+paste) I took from the JCR version available
to universities in Spain. I just reproduced the computations.
I would be glad to hear other people who has access to
the JCR. Please,could you tell me if I am using the right numbers?

Regards
Juan Miguel Campanario
