Scientists: You can judge a book by its smell
Scientists have developed a new test to measure the condition of old books and precious historical documents - on the basis of smell.A team of academics from University College London say the musty smell of an old book is the result of hundreds of so-called volatile organic compounds (VOCs) released into the air from the paper.
This means that simply by 'sniffing' books it is possible to assess the condition and suggest how a book should be stored to keep it at its best.
It's claimed the new non-destructive "sniff" test could help libraries and museums preserve a range of prized paper-based objects.
The traditional test involves removing samples of the document which causes obvious physical damage… but at least doesn't get you a odd reputation with librarians.
Matija Strlič of University College London said: "The aroma of an old book is familiar to every user of a traditional library
"A combination of grassy notes with a tang of acids and a hint of vanilla over an underlying mustiness, this unmistakable smell is as much a part of the book as its contents.
"The particular blend of compounds is a result of a network of degradation pathways and is dependent on the original composition of the object including paper substrate, applied media, and binding."
