Establishing the condition of old books and precious historical documents traditionally involves removing samples of the paper from the valuable archival materials for testing in a laboratory. Naturally such destructive forms of testing are far from ideal. Now scientists have come up with a better option with the development of a nondestructive “sniff” test that can measure the degradation of old books and documents based on their smell.
