One book that changed your life. That would have to be Human Scale, by Kirkpatrick Sale. The little factoids in the economics section (like corporate welfare sometimes exceeding total corporate profits, and Ralph Borsodi's findings on the greater efficiency of many forms of home production), and the material on decentralized production technology, got me started on the lines of economic thinking I've followed ever since.
One book that you have read more than once. The Illuminatus! Trilogy (Shea and Wilson) and the Fall Revolution trilogy (Ken Macleod).
One book that you would want on a desert island. Way too hard to narrow down. Probably an encyclopedia or some similar reference work. Or some really big canonical tome like the Bible or Shakespeare's collected works or Grimms' Fairy Tales.
One book that made you laugh. Any of the Dilbert management books.
One book that made you cry. Goncharov's Oblomov, believe it or not. I read it for a Russian lit class, and got all misty-eyed when he died. On the other hand, I laughed myself silly watching DiCaprio go under in Titanic.
One book you wish had been written. Probably SEK3's Counter-Economics.
One book you wish had never been written. Right now, for reasons I can't go into, it's Fish! A Remarkable Way to Make Your Employees Happy About Being Treated Like Shit.
One book you are currently reading. A bunch of stuff on industrial sabotage, asymmetric warfare, fourth-generation warfare, netwar, and the like.
One book you have been meaning to read. Capitalism, by George Reisman. No, really.
Now tag five people. Uh, nope, nope, nope--ain't agonna do it.
