Paper and photographs can be damaged by improper storage. Light, moisture, and temperature all can deteriorate your comic book collection, trading cards, basketball cards, memories and important legal certificates. Proper document preservation is needed.
Photos and paper items thrive in a cool, dry place. Some suggest keeping these types of valuables in an environment that is around 40% relative humidity and a temperature between 50°F and 65°F. Use a thermostat, humidifier or dehumidifier to control the environment. The biggest enemy is extreme conditions, and light (particularly sunlight or fluorescent lights). Avoid using the attic for storage unless it’s climate controlled. If storing in the basement, do not set boxes directly on the concrete as this can leach away moisture, as well as conduct cold. To help protect items from flood damage, store everything at least a foot or two off the ground. If storing on a lower floor of your home, avoid keeping items directly below potential sources of leaks. Examples include a bathroom, washer/dryer, or dishwasher. For best results, continually monitor humidity, temperate, and potential leaks.
