The Nordic Council Literature Prize is awarded for a work of literature written in one of the languages of the Nordic countries, that meets "high literary and artistic standards". Established in 1962, the prize is awarded every year, and is worth 350,000 Danish kroner (2008). Eligible works are typically novels, plays, collections of poetry, short stories or essays, or other works that were published for the first time during the last four years, or in the case of works written in Danish, Norwegian, or Swedish, within the last two years. The prize is one of the most prestigious awards that Nordic authors can win.
