The impact factor list used to be part of the Science Citation Index
until the late 80's. Then ISI decided to publish them separately which
lead to the lists being only rarely available since many libraries
continued to order the Science Citation Index but would not order the
"Journal Citation Reports" or whatever ISI started to call the list.
However, you might be able to find it in a good university library.
Here is a very partial list, compiled from the 1993? issue (quoting
this is probably at the border of legality since it ignores the
copyright of ISI; however, I might be able to claim fair use):

The value of impact factors is questionable. Personally I think they
increase the competition among journals (many journals have started
to advertise with their impact factors).
