Why do old books smell of old books?...... Smelling is probably the human sense we understand least - and I'm going to do a little bit about "smell science" this week. What's your favorite smell? Probably something to do with food or something that subconsciously reminds you of a place where you were happy. Lots of people like the smell of old books, even though they smell of age and decay! So why do old books smell the way they do?
