Things You'll Need
Instructions
Touch the letters as little as possible. Do not attach anything to them that could harm them such as glue or paper clips.
Scan the letters onto your computer so that you have a permanent record of them. If you do not have a scanner, take them to a office supply store where you can use scanners for a small fee. Keep them in a file on your computer and also save them onto a CD, DVD or external hard drive.
Place the letters in separate 8.5 by 11 inch archival sleeves. These sleeves are made of special material that helps protect paper. Archival sleeves can be purchased at office supply stores or through mail order companies such as Archival Products, Gaylord Bros. and Light Impressions.
Place the archival sleeves into an archival box where they can be stored flat. Place the box in an area that does not have a lot of humidity, such as an office or bedroom. They should not be stored in damp basements or cellars, garages, near pipes, in bathrooms or anywhere they may be accidentally damaged. Keep the temperature to 70 degrees Fahrenheit or lower.
