You might also keep your eyes open for a copy of the October 13, 1997 issue of The New Yorker. It was here that Annie Proulx's original story 'Brokeback Mountain' was first published. There are some slight variations between this printing and subsequent ones, not least of them being the addition of the italicized prologue in all later publications. This prologue was always part of Proulx's conception of the story, but it was omitted in The New Yorker due to editorial oversight.
