Judging a Book by Its Odor
A study in the journal Analytical1 Chemistry identifies various organic compounds that old books give off and that can be analyzed2 noninvasively, offering important clues to an historic work's condition and prognosis. Steve Mirsky reports
“This book stinks3!” is really a bad review. But even a classic work can start to smell when it gets old enough. Now chemists have developed a technique that identifies what kind of degradation4 process an old book or historical document is going through, based on the odors it gives off. The report appears in the American Chemical Society journal Analytical Chemistry.
An old book’s familiar musty smell is due to hundreds of different volatile5 organic compounds gassing out from the paper and other materials, such as the binding6. The particular blend of compounds results from specific degradation pathways. Conventional analysis techniques require small samples of the work for testing, further damaging the book. But analyzing7 the gases coming off of the old books is noninvasive.
The researchers identified 15 organic compounds that made good markers to track the condition of books. They note that their system could be used to evaluate the type of document, its present condition and its likely future, thus helping8 preservationists map a strategy to save historical works.
