We started the week expecting to publish one David Foster Wallace post. Then, because of the 50th birthday celebration, it turned into two. And now three. We spent some time tracking down free DFW stories and essays available on the web, and they’re all now listed in our collection of Free eBooks. But we didn’t want them to escape your attention. So here they are — 23 pieces published by David Foster Wallace between 1989 and 2011, mostly in major U.S. publications like The New Yorker, Harper’s, The Atlantic, and The Paris Review.
