Sources of dates
STORY DATE REFERENCE
- *A Boy's Best Friend Given the speed with which space is being explored and settled, a date of 1980 for the establishment of Lunar City seems reasonable. Assuming Anderson Senior was one of the original settlers, that places the story in 1995.
- *Robbie Stated in I, Robot.
- *Robot AL-76 Goes Astray After robots are banned from Earth in 2003-2007, before Susan Calvin joins US Robots in 2008.
- *Insert Knob A in Hole B Before the use of robots on space stations, hence before Reason.
- *Runaround Stated in I, Robot.
- *Reason Six months after Runaround.
- *Catch That Rabbit Six months after Reason.
- *Safety First Stated in story.
- *Liar! Stated in I, Robot.
- *Satisfaction Guaranteed Characters have the same titles as in Liar. Susan Calvin is more knowledgable about emotions than in Liar!, so the story takes place later.
- *Balance Susan Calvin's robotic servants flatter her in a manner similar to Herbie from Liar!, but she seems much more at ease with the idea, which places the story after Liar!
- *Lenny Peter Bogart is now Senior Mathematician, so the story comes after Satisfaction Guaranteed.
- *Blot Story of the first exploratory mission to Miranda. Given a mission to Mars in 1998 and a first expedition to Mercury in 2005, a mission to Uranus in 2026 seems reasonable.
- *Little Lost Robot Stated in I, Robot.
- *Escape Within a few months of Little Lost Robot.
- *Cal Cal seems to be the prototype for the EZ robots of Galley Slave, so allowing a couple of years for the design and production of the latter places the story in 2031.
- *Evidence Stated in I, Robot.
- *PAPPI Immediately after Evidence.
- *Risk Takes place 'some years' after Little Lost Robot.
- *Galley Slave Stated in the story.
- *First Law Stated in the story.
- *Plato's Cave Shortly before Stephen Byerly becomes Regional Coordinator.
- *The Evitable Conflict Stated in I, Robot.
- *Robot Dreams Late in Susan Calvin's career with US Robots.
- *I, Robot The links between the stories are set fifty years after Susan Calvin joins US Robots in 2008.
- *Feminine Intuition Five years after Susan Calvin retires from US Robots.
- *The Fourth Law of Robotics Susan Calvin's great-niece has her job.
- *Christmas Without Rodney Slighting reference to the 20th century suggests the story takes place in the 21st. Common use of robot servants suggests the latter part of the century, when the Frankenstein Complex has faded away.
- *Kid Brother Acceptance of household robots on Earth dates the story to the same general era as Christmas Without Rodney and Light Verse.
- *Robots in Time Stated in volume 1, Predator
- *Light Verse Features a robot that is capable of original artistic expression (as was Andrew Martin), at a time when robot servants are accepted (as was Andrew Martin). These both suggest that the story takes place near the beginning of The Bicentennial Man.
- *Too Bad! Sometime in the 22nd century, before the creation of the simplified robots in That Thou Art Mindful of Him.
- *That Thou Art Mindful of Him Takes place about two hundred years after US Robots is founded (i.e. circa 2182). Mentions that the Machines phased themselves out of existence a hundred years earlier (circa 2082).
- *Carhunters of the Concrete Prairie The combination of interstellar exploration and robots places this story at the time of the settlement of the Spacer worlds.
- *The Bicentennial Man Andrew Martin is about a hundred years old nearly two centuries after Susan Calvin's death in 2064.
- *Mother Earth Takes place at the end of the first few centuries of interstellar travel when the Outer Worlds were controlled, politically and economically, by Earth. (quotations from The Caves of Steel, Chapter 5).
- *The Caves of Steel Takes place a thousand years after emigration to the Outer Worlds ends. It also takes place 19 years after Elijah Baley first meets Jessie Navodny back in '02.
- *The Naked Sun Takes place one year after The Caves of Steel.
- *Mirror Image Takes place one year before The Robots of Dawn i.e. one year after The Naked Sun.
- *Strip-Runner Takes place after Elijah Baley starts his Outside group, but shortly before The Robots of Dawn (since the events in that novel aren't mentioned in the story).
- *The Robots of Dawn Takes place two years after The Naked Sun.
- *Robot City Takes place about twenty years before Robots and Empire (Han Fastolfe is still alive, and the number of Settler worlds is smaller than in Robots and Empire)
- *Robots and Aliens Takes place one year after Robot City.
- *Mirage Features older versions of characters from the Robot City series, but takes place before the disappearance of the Solarians in Robots and Empire.
- *Robots and Empire Takes place two hundred years after The Robots of Dawn.
- *Caliban Takes place a century after the Solarians vanish.
- *Inferno Takes place one year after Caliban.
- *Utopia Takes place one year after Inferno.
- *The Stars, Like Dust Takes place a thousand years after Earth suffers nuclear bombardment (perhaps in an attack by the more conservative Spacer worlds).
- *The Currents of Space Takes place five centuries before the founding of the Galactic Empire. (Note: Foundation's Edge takes place about 22,000 years after interstellar travel begins, i.e. AD 24,000. This is 12,566 years after the founding of the Galactic Empire, which sets the Empire's foundation around the year AD 11,500. For no good reason, I've chosen AD 11,585 for the year 1 GE.)
- *Pebble in the Sky Stated in the novel.
- *Blind Alley Stated in the story.
- *Prelude to Foundation Stated in the novel.

- *Wanda Seldon Ten years after Dors Venabili.
