How can one effectively preserve a drawing for long-term storage and display?

To effectively preserve a drawing for long-term storage and display, it is important to use acid-free materials such as paper and matting, protect it from light and humidity by using UV-filtering glass or acrylic, and store it in a cool, dry place away from direct sunlight. Additionally, framing the drawing with archival materials and avoiding touching it with bare hands can help maintain its quality over time.
