They held up? Good to hear.
I have been revisiting some favorites from my youth.
The Foundation Trilogy did not hold up.
In another category, Neither did the Winds of War.
The Foundation Trilogy went a bit further. Ultimately Asimov combined the Robot series into it.
I did not read the last book that Isaac wrote, but I have it around here somewhere.
I saw Asimov speak once at Suffolk University in Boston. He was quite affable. Funny though, he sounded foolish to me when he expressed certain notions. I was about 20 and he was likely approaching 70.
I like his books more than I liked his appearance that day.
