I liked "The Door Into Summer" Heinlien. "The Moon is a Harsh Mistress" was also very good. "The Day After Tomorrow" is one of my favourites. A.E.Van Vogt's "The House That Stood Still", and Lloyd Biggle Jr's "Monument" are just excellent. Azimov's "Caves of Steel" & "The Naked Sun" and all the Foundation books... There just isn't enough room to list all my favoiurites!
