Care information for collectors
NATIONAL GEOGRAPHIC magazine is collected by millions of
people around the country and the world. If you collect NGMs, you want
to do everything you can to keep your valuable collection in good
condition for as long as possible.
Paper produced in the late 19th
and throughout the 20th centuries varies a great deal in quality and
life expectancy. Daily newspapers degrade visibly in a matter of days,
while papers of the highest quality rival the older rag papers in
stability. NATIONAL GEOGRAPHIC magazine is printed on 55 pound (81 grams
per meter squared) paper coated with a standard latex/casein/clay
coating, and bound in a 100 pound (148 grams per meter squared) cover
stock with a similar coating. This paper and the synthetic inks used
assure a long life expectancy for the magazine. But all organic
materials deteriorate as they age, so proper care and handling are
essential to maximize the life of your collection. The state of
preservation, the life expectancy, and the value of your collection are
affected by these factors:
