This week, the Library of Congress revealed 25 new additions to the National Film Registry.  If you’ve never heard of this before, read on.

The National Film Preservation Act of 1992 created the National Film Registry to preserve films in perpetuity if they are “culturally, historically or aesthetically” significant.  Each year, 25 new films are added to the Registry.  The 25 additions for 2007 now bring the Registry’s total holdings up to 475 films.

Interestingly, as Librarian of Congress James Billington revealed, “up to half the films produced in this country before 1950 - and as much as 90 percent of those made before 1920- are lost forever. The National Film Registry seeks not only to honor these films, but to ensure that they are preserved for future generations.”
