Comic book preservation involves the methods and practices used to protect and maintain comic books for future generations. This includes storing them in controlled environments, using protective sleeves, and avoiding exposure to light and humidity, which can cause damage over time. Collectors and institutions often focus on preserving the original artwork and printed materials, ensuring that the history and cultural significance of comics are not lost. Organizations like the Library of Congress and various comic book stores may offer resources and guidelines for proper preservation techniques to help enthusiasts care for their collections.
