Of what use is the nose to reading? The nose is a place to perch one’s spectacles, to be sure. People trying e-books for the first time complain about the missing smell of leather and ink and pages. Print books today are mostly covered in cardboard, not leather. Get a leather cover for your Kindle and every read will smell bookish. The scent of fresh ink is just chemicals: oil and dye, solvent and finisher. Old pages are dust and mold. E-books are an improvement. Still, the nose always knows. The olfactory bulb is part of the brain’s limbic system, associated with memory and feeling. Read about an orchid. The elusive smell is activated. Is it raspberry or coconut? It is delicate and exotic, reminiscent of a past love. Encounter the smell elsewhere, the book comes back. The nose will continue to play a role in reading, print and digital.
