... I don't read nearly as much as I should. I actually really liked the Issac Asimov stuff someone (Danoss? I forget) recommended, and I read through I Robot and two of the Baley books. I'll return to that series eventually, but I was getting a little burned out on the concept.
That was me, and you're fucking welcome.

Don't worry about the rest of the series if you've read Caves of Steel and The Naked Sun.
Your next stop should be the Foundation trilogy. I say trilogy, even though there are 7 of them but go with Foundation, Foundation and Empire and Second Foundation. They are all short books.
If you enjoy them, then you can go on with the rest (which have a bit more of a time investment required).
For a standalone Asimov story, consider The Gods Themselves too.
