"As repositories 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, that may exist only in the vague memory of a reader or in the vaguer-still memory of tradition and legend, but they have acquired a kind of immortality."
--- Alberto Manguel, 'The Library at Night' (p.123)
