The National Film Registry is a list of movies deemed "culturally, historically or aesthetically significant" that are earmarked for preservation by the Library of Congress. They are not selected as the "best" American films of all time, but rather as works of enduring importance to American culture. They reflect who we are as a people and as a nation. The Librarian of Congress makes the annual selections to the Registry after reviewing hundreds of titles nominated by the public and conferring with Library film curators and the distinguished members of the National Film Preservation Board.

This searchable filmography documents the work of some 1,000 major jazz and blues figures in over 20,000 cinema, television and video productions. This filmography is for informational purposes only and does not reflect the holdings of the Library of Congress.

The American Silent Feature Film Database, which was created in conjunction with the report "The Survival of American Silent Feature Films: 1912-1929," contains searchable information for nearly 11,000 U.S. feature films, including which U.S. and international archives hold materials on the 3,300 titles for which film elements are known to exist. The American Silent Feature Film Database is a cooperative project of the Library of Congress Packard Campus for Audio Visual Conservation and the International Federation of Film Archives (FIAF).

In 2006 the National Film Preservation Foundation published The Field Guide to Sponsored Films by Rick Prelinger. Made possible by a grant from the Mellon Foundation, this annotated filmography singles out 452 sponsored films of particular historical, cultural, and artistic interest from the more than 300,000 thought to have been made. From animated propaganda in Technicolor to a call for racial tolerance from Frank Sinatra, these films often go overlooked in the study of film history. Made by corporations, schools, medical organizations, religious groups, political entities, and more, these films were produced to record, orient, train, sell, and persuade. The NFPF has partnered with the Library of Congress and the Internet Archive to make 102 films featured in the guide available for viewing, with most also available for free download. Also contributing to this digital access project are A/V Geeks, George Eastman Museum, Hagley Museum and Library, The Museum of Modern Art, National Archives and Records Administration, Northeast Historic Film, Prelinger Archives, Smithsonian's National Museum of American History, UCLA Film & Television Archive, and USC School of Cinematic Arts Hugh M. Hefner Moving Image Archive.

The Library of Congress and WGBH in Boston have embarked on a project to preserve for posterity the most significant public television and radio programs of the past 60 years: The American Archive of Public Broadcasting. The American people have made a huge investment in public radio and television over many decades, calculated at more than $10 billion. The American Archive will ensure that this rich source for American political, social, and cultural history and creativity will be saved and made available once again to future generations.

The Vanderbilt Television News Archive is a collection of both scheduled and special news broadcasts from major networks.

Broadcasts may also be viewed at the Moving Image Research Center, as Vanderbilt sends copies of the broadcasts to the Library for preservation.

The Prelinger Archive, founded in 1983 by Rick Prelinger in New York City, was acquired by the Library of Congress in 2002.
