Publication order
7 volumes1951–1993Completed
- Read in publication order: the classic trilogy (Foundation, Foundation and Empire, Second Foundation), then Foundation's Edge and Foundation and Earth, and the prequels Prelude to Foundation and Forward the Foundation last.
- Chronological order (prequels first) spoils the trilogy's ending.
A plan for the whole series
7 volumes, 2,576 pages, about 45 hours. At 45 min a day that is about 9 weeks.
Share of volume 1’s readers who reach the last volume. Chance of reaching the last volume: low
- From volume 2 on, the number of ratings falls most before volume 6, “Foundation's Edge” (by 46%). Plan your break after volume 5, before the series plans it for you.
- Readers scored volume 7, “Foundation and Earth”, below its predecessor (7.8 after 8.2). If you slow down there, that is on the book, not on you.
Stages
4 stages, with 3 short books from outside the series between them. You finish around January 16, 2027, 16 days later than in one go.

How this plan is calculated
The plan comes from the pages and ratings of each volume: we split the series into stages of about three weeks’ reading, size each break to the stage before it, and read the chance of finishing from how many readers rate the last volume compared with the first. How we work out the plan →
