[Until the publication of The Nick Adams Stories], the stories involving Nick have always appeared so many to a book, in jumbled sequence. As a result the coherence of his adventures has been obscured, and their impact fragmented. (p. 5)

Arranged in chronological sequence, the events of Nick's life make up a meaningful narrative in which a memorable character grows from child to adolescent to soldier, veteran, writer, and parent—a sequence closely paralleling the events of Hemingway's own life. In this arrangement Nick Adams, who for a long time was not widely recognized as a consistent character at all, emerges clearly as the first in a long line of Hemingway's fictional selves. Later versions, from Jake Barnes and Frederic Henry to Richard Cantwell and Thomas Hudson, were all to have behind them part of Nick's history and, correspondingly, part of Hemingway's.

As is true for many writers of fiction, the relationship between Hemingway's work and the events of his own life is an immediate and intricate one. In some stories he appears to report details of actual experience as faithfully as he might have entered them in a diary. In others the play of his imagination has transformed experience into a new and different reality. (pp. 5-6)

The first Nick Adams fiction appeared almost a half-century ago, the last in 1933, and over the years a great deal has been written about it. Among the unpublished manuscripts Hemingway left behind him, however, eight new contributions to the over-all narrative were discovered. Presented here [in The Nick Adams Stories] for the first time, inserted in the places in time where the events fall, they are varied in length and apparent purpose. Three accounts—of how the Indians left the country of Nick's boyhood, of his first sight of the Mississippi, and of what happened just before and after his wedding—are quite brief. If the author had larger plans for any of them, such are unknown; they might be read simply as sketches in an artist's notebook. In two other cases his plans are self-evident, for here we have the beginnings of works that were never completed. Nick on board the Chicago, bound for France during World War I, was the start of a novel called Along with Youth that was abandoned long ago. Similarly, though much later, the plot of "The Last Good Country" was left in midair, and many pages would have been required to resolve it. Two other pieces are known to have originated in Nick stories already published. "Three Shots" tells how the young boy became frightened while on a camping trip. It once preceded the story called "Indian Camp." And Nick's "stream of consciousness" reflections on his writing career once (anachronistically) concluded "Big Two-Hearted River." Of these new works only "Summer People," very likely the first fiction Hemingway wrote about Nick Adams, can be regarded as a full-length, completed story. (pp. 6-7)

[These] pieces throw new light on the work and personality of one of our foremost writers and genuinely increase our understanding of him. (p. 7)
