The National Book Awards are a set of annual U.S. literary awards. At the final National Book Awards Ceremony every November, the National Book Foundation presents the National Book Awards and two lifetime achievement awards to authors.
The National Book Awards were established in 1936 by the American Booksellers Association, abandoned during World War II, and re-established by three book industry organizations in 1950. Non-U.S. authors and publishers were eligible for the pre-war awards. Since then they are presented to U.S. authors for books published in the United States roughly during the award year.
The nonprofit National Book Foundation was established in 1988 to administer and enhance the National Book Awards and "move beyond [them] into the fields of education and literacy", primarily by sponsoring public appearances by writers. Its mission is "to celebrate the best literature in America, expand its audience, and ensure that books have a prominent place in American culture." (Wikipedia, CC BY-SA 3.0)
