Reading Order
First-time readers should start in publication order with Foundation (1951), not chronological order. This page is a path generator plus a map of all 15 books.
Bottom line: Begin with the original Foundation trilogy (1951–1953). Chronological order — Robot, then Empire, then Foundation — is a later reread option, not the best first pass. For the full argument, Core Seven path, and publication vs chronological comparison, read the 15-book reading order guide.

Publication Order First, Chronological Later
The map below is chronological: Robot, then Empire, then Foundation. That order follows the internal timeline, but it is not the best way in. Asimov wrote the original trilogy first; the prequels and the Robot–Empire bridge came decades later and spoil discoveries the early books are built around.
First-time readers should start with Foundation (1951), then Foundation and Empire and Second Foundation. After that, the sequels, Robot novels, and Empire novels make more sense.
Chronological order is useful on a reread: the Robot series introduces the Three Laws and R. Daneel Olivaw; the Empire novels show the rise of Trantor; the Foundation novels then show the fall.
Together these 15 books span about 20,000 years of future history. Use the generator above if you want a shorter path; use the reading order guide if you want the full comparison.
