I picked up a bunch of Asimov books tonight, and among them are his Foundation books.
I'm pretty sure I've got everything in the series, though as I understand it, he tied in some of his other series to the same universe later on.
The books I have are as follows:
Prelude to Foundation
Forward the Foundation
Foundation
Foundation and Empire
Second Foundation
Foundation's Edge
Foundation and Earth
What I'm wondering is, should I start with the preludes, or should I begin with Foundation itself and read everything as it was published (putting the preludes at the end)?
