The article deserves careful examination (more so than what i have just made) of the evidence for the lead sent. Gleick may or not have used the word for "finding earlier citations of a particular term than those already known" but i'd be surprised if his popular article, uh, antedates the usage by the world's most authoritative dictionary of English. (about which he wrote): "Antedating is the technical lexicographic term for an earlier example of a word or sense.", which is BTW more compatible with the non-lexicographic use of the word. Gleick's term should be checked against the NYT's text, and at best it should presumably be described as his usage.
