The Pulitzer Prize for General Nonfiction is one of the seven American Pulitzer Prizes that are awarded annually for the "Letters, Drama, and Music" category. The award is given to a nonfiction book written by an American author and published during the preceding calendar year that is ineligible for any other Pulitzer Prize. The Prize has been awarded since 1962; beginning in 1980, one to three finalists have been announced alongside the winner. Source: Wikipedia (en)
