The journey of books from cotton-based paper to wood pulp and finally to acid-free materials has shaped how they smell today. This article explores why the old book smell fascinates us and how it’s tied to our emotions and memories.

I’ve spent years studying the science of book scents, and as the co-founder of Frostbeard Studio, we’ve created candles that capture these beloved fragrances to improve your reading experience.

What Causes the Old Book Smell?

The old book smell is a fascinating blend of chemistry and nostalgia. But what exactly causes this scent that so many of us find irresistible?

Chemical Breakdown

Books are made mostly of paper, which is derived from plants. Over time, the materials in books break down through a process called chemical decomposition. This breakdown releases various compounds into the air, creating the distinct smell we associate with old books.

Volatile Organic Compounds (VOCs)

As books age, they emit volatile organic compounds (VOCs). These are tiny particles that evaporate easily and contribute to the unique scent. Different VOCs are responsible for different parts of the smell.

Lignin

One of the main culprits behind the old book smell is lignin. Lignin is a polymer found in plants that helps bind cellulose fibers together. When paper is made from wood pulp, it contains a lot of lignin. Over time, lignin breaks down and produces acids that degrade the paper, releasing a variety of VOCs in the process.

Vanillin, Toluene, and Furfural

Several specific compounds contribute to the old book smell:

• Vanillin: This compound gives vanilla its scent and is released as lignin breaks down. It adds a sweet, slightly woody note to the smell of old books.
• Toluene: Often found in adhesives and solvents, toluene adds a chemical, almost gasoline-like aroma.
• Furfural: This compound smells like almonds and is produced when the cellulose in paper degrades.

Each of these compounds adds a layer to the complex scent profile of an old book, making it more than just a musty odor.

The Role of Time

The age of the book also plays a significant role. Older books, especially those printed before 1845, were made from cotton and linen rags. These materials contain more stable cellulose and less lignin, meaning they degrade more slowly and release different VOCs compared to modern paper made from wood pulp.

Modern Books

Since around 1970, many books have been printed on acid-free paper, which contains less lignin. These books degrade more slowly and don't produce the same intense old book smell as their older counterparts. However, even acid-free paper will eventually break down, releasing its own set of VOCs over time.

Understanding the chemistry behind the old book smell helps us appreciate why this scent is so evocative and cherished. It's a blend of history, science, and a touch of magic that transports us back to different times and places.

Next, we'll explore why people love the smell of old books so much and how it connects to our emotions and memories.

The Science Behind Old Book Smell

The old book smell isn't just a nostalgic whiff; it's a fascinating chemical journey. Let's explore the science behind this beloved scent.

Acid Hydrolysis

The process of acid hydrolysis plays a key role in the aging of books. As books get older, the acids in the paper start breaking down the cellulose and lignin. This breakdown releases various compounds that contribute to the scent we love.

Cellulose and Lignin

Cellulose and lignin are the main components of paper. Cellulose is a complex carbohydrate that gives paper its structure, while lignin is a polymer that binds cellulose fibers together. Over time, lignin breaks down through acid hydrolysis, releasing a mixture of volatile organic compounds (VOCs).

VOC Analysis

Volatile Organic Compounds (VOCs) are the tiny particles responsible for the distinct smell of old books. When lignin and cellulose decompose, they release VOCs into the air. Each VOC adds a unique note to the overall scent.

Researchers like Strlič et al. have used VOC analysis to study these compounds. By examining the VOCs released from old books, they can identify the specific chemicals involved and understand the degradation processes at work.

Material Degradomics

The field of material degradomics focuses on understanding how materials like paper degrade over time. By studying the VOCs emitted from old books, scientists can pinpoint the chemical reactions taking place. This helps preservationists take steps to slow down or reverse the degradation process.

Key Compounds

Several specific compounds contribute to the old book smell:

• Vanillin: Adds a sweet, vanilla-like scent.
• Toluene: Provides a chemical, almost gasoline-like aroma.
• Furfural: Smells like almonds and is produced when cellulose degrades.

The Role of Time

The age of the book significantly impacts its smell. Older books, especially those made before 1845, were crafted from cotton and linen rags, which contain more stable cellulose and less lignin. These materials degrade more slowly, releasing different VOCs compared to modern paper.

How to Get Rid of Unwanted Old Book Smell

While the old book smell is a treasure for many, sometimes it can be a bit too much, especially if it's tainted with mustiness, smoke, or mildew. Here are some effective methods to freshen up your beloved books:

Airtight Container and Baking Soda

One of the most popular methods to remove musty odors is to place your dry books in an airtight container with an open box of baking soda. Baking soda is a natural deodorizer that absorbs unwanted smells. Leave them together for about a week to see noticeable results.

Fresh Air

Sometimes, a bit of fresh air is all your books need. Place your books in a well-ventilated area, preferably outdoors but not in direct sunlight, to help dissipate the musty smell. A few hours to a day of airing out can make a significant difference.

Kitty Litter

Clean, unscented kitty litter can also work wonders. Similar to baking soda, kitty litter absorbs moisture and odors. Place your books in a container with a layer of kitty litter at the bottom. Ensure the books are not in direct contact with the litter by using a perforated tray or mesh. Seal the container and leave it for a few days.

Deodorizers

For mildew smells, using closet deodorizers can be effective. Place your books in a bin with these deodorizers, and let them sit for a while. Replace the deodorizers as needed until the smell is gone. For more stubborn cases, combining deodorizers with baking soda can improve the effect.

Paper Towels and Freezer

For smoke odors, try interleaving the pages with paper towels to absorb the smell. You can also place the books in the freezer. Freezing can help neutralize odors and kill any mold spores that might be causing the smell.

By using these methods, you can enjoy the old book smell you love without the unwanted mustiness, smoke, or mildew.
