The Hitchhiker's Guide to the Galaxy is a wholly remarkable book. Perhaps the most remarkable, certainly the most successful, ever to come out of the great publishing corporations of Ursa Minor. More popular than The Celestial Homecare Omnibus, better selling than and more controversial than Oolon Colluphid's trilogy of philosophical blockbusters, Where God Went Wrong, Some More of God's Greatest Mistakes, and Who Is This God Person Anyway? It's already supplanted the Encyclopedia Galactica as the standard repository of all knowledge and wisdom for two important reasons. First, it's slightly cheaper, and second, it has the words "Don't Panic" printed in large, friendly letters on its cover.
