Why Do People Smell Books: Psychology explains that people who smell books before reading them do not do it just for fun; it’s fading history pulling us towards it

Have you ever noticed that whenever we pick a book, be it a novel or when our parents have got us a new book set at the beginning of the school’s academic session, our first instinct is to dive our noses into the pages, to get a smell of the paper, new or old!It feels no less than a stimulus, and we pause to wonder whether the book smells like chocolate, coffee, wood smoke, or something faintly like vanilla. Some people find the habit a little strange when they catch themselves doing it, while others do it openly, without a second thought. Either way, it’s far more common than most of us realize, and it isn’t just a quirky personal habit.But why do we do it? Is it just for fun, or something else?Let’s find out what research says about it

Why do we instinctively smell books when we catch on one

There is actual science behind why a book’s scent feels so evocative, running as a combination of chemistry, memory, and the way we connect with objects that carry history. Perfumers have even tried bottling the smell of an old book into candles and colognes, which says something about how universally appealing this scent really is. So what’s actually happening when we inhale that familiar, musty-sweet aroma?

What is present inside of the book which makes it so familiar to smell

The scent of an aging book comes down to chemistry. As paper breaks down over time, it releases volatile organic compounds (VOCs), and the chemical molecules evaporate easily at room temperature and reach our noses as smell.According to the study “Smell of Heritage: A Framework for the Identification, Analysis and Archival of Historic Odours” by Cecilia Bembibre and Matija Strlič, researchers at University College London, odours are associated to how closely we experience history, and can even be treated as a form of cultural heritage.The more a paper’s materials degrade, the more VOCs it releases, and different paper compositions break down in different ways, producing different scent profiles depending on a book’s age, materials, and storage conditions.

The Historic Book Odour Wheel

To make sense of these scent variations, Bembibre and Strlič developed the Historic Book Odour Wheel, a chart that classifies book smells by category, associating each scent description to the chemical compounds that can be responsible for it. Bookkeepers use tools like this to evaluate a book’s condition just by smell, sometimes without even opening the cover. A chocolatey or coffee-like scent, for instance, often means specific degradation of compounds, while other smells can mean to have a mold, moisture damage, or long-term chemical breakdown, giving librarians surprisingly reliable diagnostic hints.

When does the smell signal that something’s actually wrong

Not every book smell is pleasant, though. Water damage in particular tends to leave books smelling musty or moldy, a sign that the paper’s condition has been compromised. According to University of Colorado Boulder Libraries, University Libraries conservator Hillary Morgan says there’s no single hint for persistent odours, but a few at-home methods can help.She recommends sealing the book inside a smaller container placed within a larger, lidded tub filled with an absorbent material, explaining that book lovers should “place an odor-absorbing material in a large tub that has a lid.”Morgan also cautions that the book itself should never directly touch the absorbent material, and she asks that library patrons avoid trying this technique on any books that belong to the library’s own collection.So the next time you catch yourself smelling a book before reading it, know that it’s not a random habit. You’re picking up on real chemistry.
