Preserving old letters is an art. Here are a few tips for keeping them happy and healthy.

• Don’t put them in the attic.
• Plastic bins are not good for storing old letters.
• Take notes while organizing. Sticky notes are fine on folders, but not on letters.
• Keep everything from one envelope together.
• Putting all of the letters in chronological order might not be the best solution.
