Depends a little on the time of year. I don't read for leisure very much. During a study semester, I will read 30+ journal articles a week (20-40 minutes per paper), but very few books, maybe just one or two chapters a week - usually boring textbook stuff.
However this year for leisure I have read a few books including Teo Te Ching, Meditations, The Art of War, Civilizations and Discontent, Confucius, The Communist Manifesto, Utopia, The Prince, The Art of Being Persuasive and How to Win an Argument, Beyond Good and Evil, The Game of Life and How to Play it, Big Panda and Little Dragon, Utopia, Determined: A science of life without free will.
Next i'm going to tackle my first graphic novel and read V for Vendetta - I don't even like fiction, or graphic novels, but V for Vendetta is one of my fave movies, so I decided to have a crack at it.
I should read more, but sometimes I just can't be bothered.
