Foundation, Foundation and Empire, Second Foundation. I didn't like Foundation's Edge or Foundation and Earth. Prelude to Foundation and Forward the Foundation were good.

The Caves of Steel, The Naked Sun, The Robots of Dawn.

I, Robot. Robot Dreams.

Those are the important ones.

Thanks! I'm familiar with the first Foundation and I, Robot but the rest I still need to read. How'd you like "Nightfall"?--I liked that a lot.
