Preserving newspapers requires more than simply stacking them in a corner. For historians, genealogists, and casual readers alike, the physical newspaper represents a tangible link to a specific moment in time, capturing the news, language, and advertisements of a bygone era. Without proper care, however, the acidic paper stock common in publications after the mid-20th century will yellow, become brittle, and eventually disintegrate. Effective storage is therefore essential to slow down this chemical decay and protect the ink and images for future research or nostalgia.
Understanding the Enemy: Why Newspapers Deteriorate
The primary enemy of any newspaper collection is lignin, a natural component of wood-based paper. When exposed to light and humidity, lignin breaks down and causes the pages to turn yellow and crumble. Environmental factors are the biggest contributors to this process. Fluctuations in temperature cause the materials to expand and contract, while high humidity encourages the growth of mold and creates the perfect conditions for acid migration. Even the air we breathe contains pollutants that gradually settle on the pages and accelerate degradation. Recognizing these threats is the first step in creating a controlled environment for your collection.
Preparing the Collection for Storage
Before placing newspapers into long-term storage, a small amount of preparation can prevent significant damage down the line. First, ensure the newspapers are completely dry to the touch; any residual moisture can lead to mold growth when they are sealed away. You should also handle the pages with clean hands or cotton gloves to transfer oils and dirt that could stain the paper. For newspapers with large foldouts, consider whether you want to keep them folded or gently fold them back the opposite way to minimize permanent creases. While it might be tempting to use office staples or paper clips, these metal components will rust over time and stain the paper, so they should be removed if safe to do so.
Flat Storage vs. Rolled Storage
When deciding how to store newspapers, you generally have two primary options: flat or rolled. Flat storage is the most common method and involves stacking the newspapers horizontally, similar to a book. This method is space-efficient and protects the original cover or masthead if the stack is placed upright. Rolled storage, typically used for very large formats like murals or long political cartoons, involves rolling the newspaper around a sturdy tube. This prevents creases but makes it difficult to read the text without unrolling the entire piece. Choose the method that aligns with your space constraints and how frequently you intend to access the collection.
The Ideal Environment
Temperature and humidity control are non-negotiable for archival preservation. The optimal conditions for storing newspapers are cool and dry. Aim to keep the temperature below 70 degrees Fahrenheit (21 degrees Celsius) and the relative humidity between 30% and 50%. Basements are generally unsuitable due to high humidity, while attics can become excessively hot. A climate-controlled bedroom or office is often the best location. If you live in an area with extreme weather, consider investing in a dehumidifier or a small archival-safe storage unit to buffer against environmental swings.
Choosing the Right Materials
Standard cardboard boxes and regular plastic bags are inadequate for newspaper preservation. Over time, the acids in these common materials will leech into the newspapers, causing them to yellow even faster. Instead, you should utilize acid-free and lignin-free supplies. Archival-quality boxes provide the rigid structure needed to prevent crushing, while interleaving paper protects the print surface. For individual issues, polyester or polypropylene sleeves are excellent choices because they are transparent, flexible, and chemically inert. Avoid PVC-based materials, as they can become sticky and damage the paper over time.
