The Encyclopedia Galactica is a respectable, but on the whole insignificant guide and sells rather less than the Hitch-Hiker's Guide to the Galaxy. It is also more expensive and older than the Guide. It has also been criticised in some quarters for the lack of friendly advice on the cover, compared to the Guide.
The Encyclopedia Galactica is mentioned in:
- The Douglas Adams book The Hitchhiker's Guide to the Galaxy.
- The first episode of the The Hitchhiker's Guide to the Galaxy television series.
- The Isaac Asimov book Foundation
Behind the scenes
