Annie Proulx was awarded the Pulitzer Prize in 1994
Brokeback Mountain author Annie Proulx is donating her papers - including an early draft of the short story - to New York's public library.
The 74-year-old, who won the Pulitzer Prize for The Shipping News, will give a wealth of material including diaries and manuscripts to the institution.
Proulx said there was "an odd sense of balance" bringing her rural US material to the big city.
The 2005 big screen version of Brokeback Mountain won three Oscars.
One of the statuettes was for the adaptation of Proulx's original story.
Early versions of the cowboy romance which will be housed in the library had working titles including Bulldust Mountain and Swill-Swallow Mountain.
Proulx added that it would be an "honour" to be in the company of authors including Walt Whitman and Mark Twain, whose papers are already housed in the library.
