“[The Great Gatsby] is a tour de force of revision. So much so that critics, who rarely mention the edit of a book, commented on the quality of Gatsby's rewriting, not just its writing, in reviews. For H. L. Mencken, the novel had 'a careful and brilliant finish. ... There is evidence in every line of hard work and intelligent effort. ... The author wrote, tore up, rewrote, tore up again. There are pages so artfully contrived that one can no more imagine improvising them than one can imagine improvising a fugue.' ... Careful, sound, carefully written, hard effort, wrote and rewrote, artfully contrived not improvised, structure, discipline: all these terms refer, however obliquely, not to the initial act of inspiration, but to editing.
Organization and clarity do not dominate the writing process. At some point, though, a writer must pull coherence from confusion, illuminate what lives in shadow, shade what shines too brightly. Gatsby is the cat's meow case study of crossing what Michael Ondaatje calls 'that seemingly uncrossable gulf between an early draft of a book ... and a finished product' - in other words, editing.”
