Comic books, like all things, change as they age and not necessarily for the better. Whether from the golden, silver or modern age, comic books are all printed on paper that is made from wood pulp. Lignin (a substance found in wood) breaks down and causes the paper to become increasingly acidic, discolored and brittle. Those of you who collect comic books have certainly seen and handled extremely brittle and discolored books. Conservators refer to this the inherent instability of wood pulp paper as “inherent vice.”

If you wish to preserve your comics, you need to take measures to combat this inherent vice by minimizing factors that accelerate deterioration. Steps that you can take to fend off inherent vice include:

  • Limiting exposure to high levels of moisture, either in the form of water or high humidity. Both can damage comics and accelerate degradation.
  • Avoiding exposure to ultraviolet and visible light, which can cause inks to fade and paper to become yellow.
  • Using inappropriate non-archival storage or display materials, such as PVC vinyl plastic bags or boxes, inexpensive wood pulp cardboard boxes, wood pulp mat boards, wooden boxes or wooden frames. Contact with these can cause discoloration.
  • Avoiding frequent handling.

 

In this video, recorded live in the conservation lab at The Henry Ford, Chief Conservator Mary Fahey demonstrates how to store, display, repair, and preserve your comic books.

What can be done to preserve comic books?

Take measures to limit exposure to moisture by placing books in archival bags or sleeves made from polypropylene, polyethylene or polyethyleneterephalate (Mylar).

Never store comic books directly on the floor.

Avoid storing books in attics, basements or other damp areas. If no alternative is available, use watertight polyethylene or polypropylene boxes and add a few silica gel packets conditioned to 45-50% relative humidity. The packets will need to be changed periodically.

Limit exposure to light including visible and invisible ultraviolet light. If you wish to display your comics, consider display methods that limit light exposure by avoiding display near windows and turning off the lights when you are not in the room. If you choose to display your books in a lighted showcase case, LEDs on a timer are the best option since they emit minimal ultraviolet light and minimal heat. At The Henry Ford, we have noticed that Mylar covers appear to block some of the damaging effects of light, providing some protection from fading.

All books should be bagged and boarded or encapsulated (see image below) for storage, display and handling. This protects them from dirt and moisture, minimizes flexing and stress of the fragile paper, and protects from the oil and salt in people’s hands. The use of archival materials and methods for storage and display can have a big impact on the longevity of your collection.

The use of acid-free, lignin-buffered mat board, boxes and paper inserts are recommended. These products are made from cotton, and generally contain calcium carbonate, which helps to neutralize the acid that is formed in the comic books as they age. They do cost a bit more, but are well worth it. The Henry Ford uses a variety of display and storage methods for comic books. Some examples include:

In a current TV series celebrities donning white cotton gloves view documents and rare books as they learn about their family history. But is this really the way that professional museum and archives staff handle the hundreds or thousands of artifacts that are entrusted to their care?

What is the logic behind this practice?

The fact is that moisture, salt and dirt on human hands can damage artifacts and embed particles of dirt onto the surface of artifacts, this can permanently harm some artifacts. In the case of uncoated metals the human hand provides the perfect combination of salt and moisture in the form of sweat to cause damage in the form of corrosion. The image below shows a fingerprint on a brass plate. Continue Reading
