Every library is a library of preferences, and every chosen category implies an exclusion. — Alberto Manguel

Most readers, then and now, have at some time experienced the humiliation of being told that their occupation is reprehensible.

Through ignorance, through faith, through intelligence, through trickery and cunning, through illumination, the reader rewrites the text with the same words of the original but under another heading, re-creating it, as it were, in the very act of bringing it into being.

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 the vague memory of a reader or in the vaguer-still memory of tradition and legend, but they have acquired a kind of immortality.
