h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

I work with the Dewey Decimal system EVERY DAY because, I work in a public reference library. Because Mr Dewey was a racist, christian type he has squashed all other religions in the late 200 If you ever find a dewey listing you will find Christianaity takes up most of the 200's leaving the last ten digits for Muslims, Hindus, etc.
He has also never heard of computers, Internet stuff is at 004/5 Word processing is in the 700's (madness if you ask me, and I'm a Librarian) There are other methods of classification that do use the alphbet but they don't make that must sense either
