I lecture frequently and am in need of material to bring out my
points. It seems that I used to get much better result from Google
researchers about a year or so ago. Is there a better way to do this?

Hi Prof,
I think Pafalafa answered this on your question about Elvis. 
Reviewing your questions, I notice that the ones that did not get
answered often called for "material, anecdotes illustrating ...".  Of
course, a good lecture needs such to enliven the presentation, but
searching for examples requires some luck since one would have to
imagine or know first a topic in which such might appear, and then
hope that examples pop up.
Kind of frustrating  - for you too, with your interesting questions.
Good luck - better luck, Myoarin

Thanks for the tips.
