From Mark Flanagan's Contemporary Lit blog http://contemporarylit.about.com/
"There is a difference between a book of two hundred pages from the very beginning, and a book of two hundred pages which is the result of an original eight hundred pages. The six hundred are there. Only you don’t see them." - Elie Wiesel
"There are books so alive that you're always afraid that while you weren't reading, the book has gone and changed, has shifted like a river; while you went on living, it went on living too, and like a river moved on and moved away. No one has stepped twice into the same river. But did anyone ever step twice into the same book? " - Marina Tsvetaeva
"I think we ought to read only the kind of books that wound or stab us. If the book we’re reading doesn’t wake us up with a blow to the head, what are we reading for? So that it will make us happy, as you write? Good Lord, we would be happy precisely if we had no books, and the kind of books that make us happy are the kind we could write ourselves if we had to. But we need books that affect us like a disaster, that grieve us deeply, like the death of someone we loved more than ourselves, like being banished into forests far from everyone, like a suicide. A book must be the axe for the frozen sea within us. That is my belief." – Franz Kafka
"You know you've read a good book when you turn the last page and feel a little as if you have lost a friend." - Paul Sweeney
