Just walk into a section of library with old books, you would definitely feel their peculiar smell. But where does this unique smell of old books come from? We explain to you everything about this phenomenon.

Matija Strlic, a researcher at the University College London has investigated this phenomenon. In a recent article in the The Telegraph he explains the reasons for this unnmistakble smell with a hint of vanilla that comes from an old book and its contents.

Indeed, the secret of the smell lies in the materials from which it is made of. As pages, glue and ink of the book are all composed of hundreds of volatile Organic Compounds ( VOCs ). With the passage of time, these Organic compounds break down resulting in release if new chemicals which give the peculiar smell. Books printed nowadays give different smell with time as they are not made of same components as old books. As, the type of different materials  used can greatly effect the type of VOC structure and hence the type of smell.

Compounds like ethylbenzene and 2-ethylhexanol give us the sensation of floral fragrance. Similarly, the flowers pressed into the books also contribute to the smell of the book with time.
