How do we preserve art that wasn't created to be preserved? Such a category would include, let's say, an artwork made partly or wholly of organic materials such as chocolate or beeswax.

that anyone has yet got the imaginative measure of that terrifying day six years ago. Certainly our Tolstoy has not crawled out of the rubble.
