I've forgotten the address of the site but the 1995 figures are:

Cell 40.481
Nature 27.074
NE Journal of Medicine 22.412
Science 21.911
Genes and Development 18.793
Neuron 16.619
Immnunity 15.354
EMBO J 13.505
J of Cell Biol 12.480
PNAS 10.520
Mol Cell Biol 10.498

I have no idea how the figures were calculated.
