The New Yorker has published Carver's story, "Beginners," which Gordan Lish edited to become "What We Talk About When We Talk About Love." You can find Carver's original here, but what's more interesting, I think, is a copy with Lish's edits, here. Lish cut about five pages, chiseled the language throughout, and wrote a few new sentences, including the last. His edits change the feel story, but they really do sharpen it and make it stronger for the most part.
