Do you like to have your nose in a book? No, we’re not talking figuratively. Something about the scent of old books can perk up any bookworm. And turns out, there’s a legitimate reason that dusty old pages actually smell good.

Volunteers blindly sniffed extracts from the book, plus seven other unlabeled scents ranging from chocolate and coffee to fish market and dirty linen. Afterward, participants filled out a survey with a question asking them to describe the smell of the historic book.

‘You tend to use familiar associations to describe smells when they are unlabeled,’ study author Cecilia Bembibre tells Popular Science. ‘And also, the VOCs of chocolate and coffee seem to be very similar to that of books.’ Sounds funny, but chocolate and coffee contain fermented or roasted chemical compounds called lignin and cellulose, which are also in decaying paper, the authors write.
