What's your favourite non fiction book

I don't read non-fiction, so maybe this thread might "inspire" me.

1984 - Thou knowest it. ;)

The Hitch hicker guid to the galaxy is a great factual book

If Chins Could Kill

Only non-fiction books I read are professional literature, even they sound far fetched sometimes, and I'm sick of them.
In all honesty I do like to read books based on real people and events but with writers spin and/or interpretations.

It would be Voyage autour du monde by L.A.Bougainville (1766-1769) because of how it inspires to think about and critique society in general (Especially when you add to it the Supplement written by Diderot).
I don't know if it was translated in English though

Guns, Germs, and Steel - Jared Diamond
The Fatal Shore - Robert Hughes
The Gulag Acchipelago - Aleksandr Solzhenitsyn (only part way through this atm)

Chariots of The Gods - Erich von Däniken

Morals & Dogma by Albert Pike

My favorite non-fiction books are reference books.

I like to read war novels, my favorites are Homage to Catalonia George Orwell and Man's Fate André Malraux.
Philosophy favorites: The Myth of Sisyphus Albert Camus, The Antichrist Fredrich Friedrich Nietzsche, Philosophy in the Bedroom Marquis de Sade, The Princ Niccolò Machiavelli, Authors preface of Hegels Elements of the Philosophy of Right, Philosophy of history Hegel, Apology Plato. These are short and fun to read

Erving Goffman? Cool, I liked very much Behavior in Public Places and bought more his books. I also read Eco, usually in Italian newspapers, not his essays. his smart political comments.

The most recent that stayed quite long in my conscience would be Alan Sokal's Fashionable Nonsense

Two books of Stephen Hawking (The Universe in a Nutshell, A Brief History of Time), The Seven Daughters of Eve, The Code Book, and some other science books.

Orwell's animal farm (It's half-fiction)

Sailing from Byzantium: How a Lost Empire Shaped the World by Colin Wells. Was a really fascinating read.

Marcus Aurelius Meditations, however i have thousands of books and 99% are non fiction, so there's choice :-)

Hannah's Gift. A mother writes about her three year old passing away from cancer. I was crying so much while reading it.

A small portion of my books, you can browse and see if you like something

The Bible.

Oh wait. That one was made up, right?

I don't typically read non fiction books, so I don't have a favorite :C. But when I do read non fiction, it's usually history.

Sorry, reality is just a bit too crazy for me. I'll stick to Fiction.

The Killing Fields.

some books from Latin American writers -> Julio Cortázar (especially "Rayuela (Hopscotch)" and all short-stories), Carlos Fuentes -"The Death of Artemio Cruz (La muerte de Artemio Cruz)", Gabriel García Márquez ("One Hundred Years of Solitude"), Mario Vargas Llosa ("Conversation in the Cathedral")
