In preparation for his unfinished novel The Pale King, David Foster Wallace immersed himself in the world of accounting and the IRS. Quartz just published two pages of DFW's notes from one of those accounting classes. There's not much there, but it's full of little notations that you can tell are revelatory to DFW—the fact that supplies are assets until they're used, when they become expenses, for instance. It's a tiny little bite-sized peek into the novel that he'll never finish. You should go take a look.
