This comes via two different blogs and originates at The Guardian's technology blog: a list of the 20 top "geek" books. I've bolded the ones I've read. One asterisk means I own it but have never finished it. Two asterisks means I'm reading it (well, Watchmen) right now. I've added senile comments as well. Dizzyheads should chime in!
1. The Hitchhiker's Guide to the Galaxy -- Douglas Adams
Am one of maybe three people who enjoyed the movie version; am listening to the old radio shows these days on iPod. I actually read the first sequel, The Restaurant at the End of the Universe, first—I started reading it at Kmart!
2. Nineteen Eighty-Four -- George Orwell
3. Brave New World* -- Aldous Huxley
I'm so embarrassed that I haven't read this that I should just read it.
4. Do Androids Dream of Electric Sheep? -- Philip Dick
I'm still not sure why the movie is called "Blade Runner"—I don't think the phrase comes up in the book.
5. Neuromancer -- William Gibson
Why haven't I read any Gibson?
6. Dune -- Frank Herbert
Had sizable impact on the young Ed, though strangely, of the sequels, I only finished Dune Messiah.
7. I, Robot* -- Isaac Asimov
Never finished this one—but did read and enjoy IA's robot detective novels (with the oddly named "R. Daneel Olivaw"—surely an anagram for something!)
8. Foundation -- Isaac Asimov
I wonder what it would be like to read Foundation again? Oddly, I think I have Foundation's Edge with me here in New York.
9. The Colour of Magic -- Terry Pratchett
10. Microserfs -- Douglas Coupland
11. Snow Crash -- Neal Stephenson
12. Watchmen** -- Alan Moore & Dave Gibbons
13. Cryptonomicon -- Neal Stephenson
14. Consider Phlebas -- Iain M Banks
15. Stranger in a Strange Land -- Robert Heinlein
I was just thinking about this one—I bought a copy in 7th grade, and it fell apart as I read it. I remember finding it slightly tedious—possibly much of it was over my head. I did enjoy some other Heinlein, later.
16. The Man in the High Castle -- Philip K Dick
Perhaps his best? I read this soon after reading Do Androids..., but liked it more later (during my big PKD phase, c. '95-96)
17. American Gods* -- Neil Gaiman
18. The Diamond Age -- Neal Stephenson
19. The Illuminatus! Trilogy* -- Robert Shea & Robert Anton Wilson
This was part of the legendary Bloomingdale library book sale haul!
20. Trouble with Lichen - John Wyndham
