The smell of old books is basically created by paper and ink. Paper is made of wood, wood is made up of organic compounds such as cellulose and lignin.
Over time, these organic compounds react with temperature, light and moisture, they begin to break down and release VOCs.VOCs are volatile organic compounds (short for Vocatile Organic Compound).
These compounds easily mix into the air, creating the aroma of old books.
There are many different types of VOCs: VOC valinin with vanilla-like scent, VOC benzaldehyde with aromatic aroma and VOC ethylbenzene with a sweet aroma.
