Frequently Asked Questions
What is the correct Hitchhiker's Guide reading order?
Publication Order. Read in publication order. The five books form one continuous (if increasingly surreal) story. A sixth, written by another author after Adams's death, is optional.
Is the Hitchhiker's Guide series finished?
Yes. Douglas Adams's five books are complete. Eoin Colfer wrote an authorized sixth, And Another Thing… (2009).
How many Hitchhiker's Guide books are there?
Five by Douglas Adams, plus a sixth (And Another Thing...) written by Eoin Colfer after Adams's death. Adams jokingly called it a 'trilogy in five parts.'
Do I need to read them in order?
Yes — later books reference earlier events constantly, and the running jokes build across the series.
