“My father believes that one should leave typos in one’s galleys uncorrected. It is a law of nature that when one opens the printed version the first thing one will see will be a mistake. If you leave the typos alone, the first thing one will see will be a typo. If you correct the typos, the first thing one will see will be a truly horrible and inexcusable substantive error…” Dr. Brad DeLong (http://tinyurl.com/25kc5um, 14 April 2005)
