Comment Preserve by analysis and copying (Score 2) 33
All of the preservation efforts for a single, unique item are likely to eventually fail - war, theft, natural disasters, etc. Preserve the works by analysis and wide distribution. The full analysis - multi-spectral imaging, chemistry, 3-d scanning, history, etc. should be available publicly. And, in the tradition of medieval monks, Arabic scribes, and even artists workshops, produce copies for display while attempting to preserve the original.
