The books aging

There is something typical in a library: how it smells and when you open an old book with its used pages then you realise it has its own story. 

Why do old books smell?

In old papers books, the composition that can be found is lignin and certain volatile organic compounds (VOCs). As time goes by, they oxidize themselves and lignin turns the pages yellow and smells like vanille.  Nowadays, books are not going to go through this process as their leaves do not really have much lignin and are neutral PH for a better conservation. And now it's time to sell Paper Passion: a perfume that smells like books and you can also find DIY about how to make books looking older with tea bags.

The essence of an old book can not be created from a new one.
