Are you claiming that everything printed after 1980 is available online?

No silly, just as a rule of thumb - somethings were digitized of course after 1981 up until say, as a rule, 2000, but by no means everything before 1980 because there was no internet and trolls were unknown - other than those that live under bridges.
Stop this pickiness, its a waste of time.
Your initial remark was addressed to me, and appeared to be lecturing me on the fact that "old" meant "before 1980" - although my prior comments (to which you were ostensibly responding) ought to have indicated that I was already familiar with such facts and so didn't need lecturing.
