In many of the more relaxed civilizations on the Outer Eastern Rim of
the Galaxy, The Hitch Hiker's Guide has already supplanted the great
Encyclopaedia Galactica as the standard repository of all knowledge
and wisdom, for though it has many omissions and contains much that is
apocryphal, or at least wildly inaccurate, it scores over the older, more
pedestrian work in two important respects.
First, it is slightly cheaper; and secondly it has the words DON'T PANIC
inscribed in large friendly letters on its cover.
