“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.”

“[...]he also had a device which looked rather like a largish electronic calculator. This had about a hundred tiny flat press buttons and a screen about four inches square on which any one of a million "pages" could be summoned at a moment's notice. It looked insanely complicated, and this was one of the reasons why the snug plastic cover it fitted into had the words Don't Panic printed on it in large friendly letters. The other reason was that this device was in fact that most remarkable of all books ever to come out of the great publishing corporations of Ursa Minor - The Hitch Hiker's Guide to the Galaxy. The reason why it was published in the form of a micro sub meson electronic component is that if it were printed in normal book form, an interstellar hitch hiker would require several inconveniently large buildings to carry it around in.”

“The Hitch-Hiker's Guide to the Galaxy also mentions alcohol. It says that the best drink in existence is the Pan Galactic Gargle Blaster, the effect of which is like having your brains smashed out with a slice of lemon wrapped round a large gold brick.”

“The Hitchhiker's Guide to the Galaxy is an indispensable companion to all those who are keen to make sense of life in an infinitely complex and confusing Universe, for though it cannot hope to be useful or informative on all matters, it does at least make the reassuring claim, that where it is inaccurate it is at least definitively inaccurate. In cases of major discrepancy it's always reality that's got it wrong.This was the gist of the notice. It said "The Guide is definitive. Reality is frequently inaccurate."This has led to some interesting consequences. For instance, when the Editors of the Guide were sued by the families of those who had died as a result of taking the entry on the planet Tralal literally (it said "Ravenous Bugblatter Beasts often make a very good meal for visiting tourists: instead of "Ravenous Bugblatter Beasts often make a very good meal of visiting tourists"), they claimed that the first version of the sentence was the more aesthetically pleasing, summoned a qualified poet to testify under oath that beauty was truth, truth beauty and hoped thereby to prove that the guilty party in this case was Life itself for failing to be either beautiful or true. The judges concurred, and in a moving speech held that Life itself was in contempt of court, and duly confiscated it from all those there present before going off to enjoy a pleasant evening's ultragolf.”

“I like the cover," he said. "Don't Panic. It's the first helpful or intelligible thing anybody's said to me all day.”

“The Encyclopedia Galactica defines a robot as a mechanical apparatus designed to do the work of a man. The marketing division of the Sirius Cybernetics Corporation defines a robot as "Your Plastic Pal Who's Fun to Be With. The Hitchhiker's Guide to the Galaxy defines the marketing devision of the Sirius Cybernetic Corporation as "a bunch of mindless jerks who'll be the first against the wall when the revolution comes,”

“In fact, Lig never formally resigned his editorship—he merely left his office late one morning, and has never returned since. Though well over a century has now passed, many members of the Guide staff still retain the romantic notion that he has simply popped out for a sandwich and will yet return to put in a solid afternoon's work. Strictly speaking, all editors since Lig Lury Jr., have therefore been designated acting editors, and Lig's desk is still preserved the way he left it, with the addition of a small sign that says LIG LURY, JR., EDITOR, MISSING, PRESUMED FED.”
