Can you guess the book?

I'm stealing this from pages turned. It's made the rounds before but I haven't done it in a long time.

1. Grab the nearest book.
2. Open the book to page 123.
3. Find the fifth sentence.
4. Post the text of the next 4 sentences on your blog along with these instructions.
5. Don't you dare dig for that "cool" or "intellectual" book in your closet! I know you were thinking about it! Just pick up whatever is closest.

"Libraries, in their very being, not only assert but also question the authority of power. As respositories of history or sources for the future, as guides or manuals for difficult times, as symbols of authority past or present, the books in a library stand for more than their collective contents, and have, since the beginning of writing, been considered a threat. It hardly matters why a library is destroyed: every banning, curtailment, shredding, plunder or loot gives rise (at least as a ghostly presence) to a louder, clearer, more durable library of the banned, looted, plundered, shredded or curtailed. Those books may no longer be available for consultation, they may exist only in vague memory of a reader or in the vaguer-still memory of tradition and legend, but they have acquired a kind of immortality."

Sheesh. Those are four long sentences. But four good sentences. Any guesses? Nothing on the blog will give you any hints I'm afraid as I've not yet mentioned this one and in fact just bought it. No clue when I'm actually going to read it but this kinda really makes me want to...
