I know there the four R. daniels novels. I was just wondering what are the other robot books and is there a reading order?
The reading order is today much debated, with some people favoring the publication order and others favoring the internal chronological order.
For a number of reasons, I don't think that internal chronological order works for first-timers, as certain developments get spoiled way
The robot novels should be read in order -- Caves
, Naked Sun
, The Robots of Dawn
, Robots and Empire
. You can read I, Robot
before, in the middle, or after, even though that book takes place very early. The other robot short stories you can read at almost any time; they have little direct bearing on the Foundation mythos.
