I found the professor - he is retired now, and lo and behold the definitions I questioned him about are nowhere to be found on his site. Here is the URL: http://public.wsu.edu/~brians/
I’m guessing I may still have a copy of our email correspondence, but that would take me a while to dig out. I might go to the WBM and see if they have an old copy of the site first.
If you find it, could you ping me to that information also?
I’d be interested in those definitions as well.
