The article recommends having a good dictionary at hand, and that is absolutely correct advice. What I'd like to suggest is that, aside from writing that absolutely must use terms from the last 100 years, use the Webster 1913[1] as your dictionary of choice. It's become a fetish, of sorts, among writers like Cory Doctorow [2] and others who approvingly link to James Somers' May 18, 2014 post, "http://jsomers.net/blog/dictionary"[3].
