CD-ROM disks, along with their higher-capacity cousins DVD and Blu-ray disks, are fragile methods of storing information. In short, these plastic disks are not suitable for long-term storage. Many corporations and non-profits are racing to get their data off the discs as quickly and safely as possible and into a more reliable digital storage environment. If you have genealogy information or any other information stored on these disks, you need to do the same.
For many years, the thought amongst genealogists has been to print the information on paper for long-term preservation. Yet, many of us have handled old pieces of paper that are decaying, crumbling, or fading to the point that the information is not readable. In fact, most paper manufactured in the past 75 years or so contains acids that will hasten the deterioration of the information you wish to preserve. Add in the many problems of paper destruction caused by mold, mildew, moisture, insect damage, floods, and other factors, and you soon come to the realization that storage on paper is almost as risky as storing on magnetic media.
