There are two answers here, a short one, and a longer one which also includes opinions on the quality of the books. From J. Hunter Johnson (jhunterj@donet.com): As with other series, the Asimov books can be read in published order or in chronological order. First-time readers should probably read the books in published order to avoid some of the spoilers present. The chronological order of the novels by Asimov or approved by his estate are: The Caves of Steel (1954) The Naked Sun (1957) The Robots of Dawn (1983) Robots and Empire (1985) Caliban (1993) Inferno (1994) Utopia (1996) The Stars, Like Dust (1951) The Currents of Space (1952) Pebble in the Sky (1950) Prelude to Foundation (1988) Forward the Foundation (1993) Foundation’s Fear (1997, takes place after the first chapter of Forward the Foundation) Foundation and Chaos (1998) Foundation’s Triumph (1999, takes place after the first chapter of Foundation) Foundation (1951) Foundation and Empire (1952) Second Foundation (1953) Found
