Film archives are collections of films, videos, and related materials that are preserved for historical, cultural, and educational purposes. These archives can include everything from classic movies to documentaries, and they often serve as a resource for researchers, filmmakers, and the general public. By preserving these works, film archives help to maintain the history of cinema and ensure that future generations can access and appreciate these important cultural artifacts. Many film archives are associated with institutions like libraries, museums, or universities, and they often engage in restoration projects to improve the quality of older films. They may also host screenings, exhibitions, and educational programs to promote awareness of film history. Notable examples of film archives include the Library of Congress in the United States and the British Film Institute in the United Kingdom.
