Audiovisual preservation refers to the processes and techniques used to protect and maintain audio and visual materials, such as films, recordings, and digital media. This practice ensures that important cultural, historical, and artistic works remain accessible for future generations. Preservation efforts often involve restoring damaged materials, digitizing content, and storing it in stable environments to prevent deterioration. Organizations like the Library of Congress and the National Film Preservation Foundation play crucial roles in audiovisual preservation. They develop standards and best practices, provide funding for preservation projects, and raise awareness about the importance of safeguarding our audiovisual heritage.
