Isaac Asimov's Robot City

Isaac Asimov's Robot City is a series of science fiction novels written by various authors beginning in 1987, and is loosely connected to Isaac Asimov's Robot series. It was originally published by Ace Books.

The concept for the novels began as a collaboration of Isaac Asimov and writer/editor/publisher Byron Preiss, with Asimov acting as a technical consultant. Byron & Asimov then issued a writing challenge to write a series involving the Three Laws of Robotics, which brought about a collaboration of several authors; Asimov provided the premise for the series, which filled in the gap between Asimov's own robot stories and his Foundation series, explaining the disappearance of the robots prior to the establishment of the Galactic Empire. He also wrote introductions for each book. Additionally, the end of each book includes a "Data Bank", which features illustrations by Paul Rivoche and paired descriptions, providing further information about characters, objects and locations from the stories.

Isaac Asimov's Robots and Aliens followed in this series starting in 1989. The overarching plot deals with the interactions between human & alien characters and their encounters with autonomous "robot cities" which are run and populated by robots.
