WASHINGTON (UPI) -- "Deliverance," "The Invisible Man," "Sergeant York" and "The Terminator" have been added to the U.S. National Film Registry of the Library of Congress.

Under the terms of the National Film Preservation Act, the Librarian of Congress each year names 25 movies to the national registry that are "culturally, historically or aesthetically" significant, to be preserved for all time.

In addition to the aforementioned films, Librarian of Congress James H. Billington Tuesday also named to the registry "A Face in the Crowd," "The Asphalt Jungle," "Disneyland Dream," "Flower Drum Song," "Foolish Wives," "Free Radicals," "Hallelujah," "In Cold Blood," "Johnny Guitar," "The Killers," "The March," "No Lies," "On the Bowery," "One Week," "The Pawnbroker," "The Perils of Pauline," "The 7th Voyage of Sinbad," "So's Your Old Man," "George Stevens WW2 Footage," "Water and Power" and "White Fawn's Devotion."

"With this year's list, the registry now includes 500 films and stands as a matchless record of the amazing creativity America has brought to the movies since the early 1890s," Billington said in a statement. "Both as a public-awareness tool and as an educational learning aid for students, the registry helps this nation understand the diversity of America's film heritage and, just as importantly, the need for its preservation. The nation has lost about half of the films produced before 1950 and as much as 90 percent of those made before 1920. In addition, more and more nitrate-based and acetate-based films are deteriorating with the passage of time."
