Lighter-
I sort of agree with you that several you questioned could have been left off... or been farther down on a longer list.

I don't think "All the President's Men" was influential... the events it described were influential. It was a good book...even an important book. But Dr. Spock & Dale Carnegie & Robert E. Heinlein & Betty Friedan were more 'influential'. (I watched them influence many college students many years ago)

My point was mostly about sticking to the point.
