This is a fun case in the study of courts relying on dictionaries (rather than legal precedent) to decide cases.
O'Grady v. Superior Court, 2006 WL 1452685 (Cal. App. 6 Dist. May 26, 2006), is about an online magazine that posted material about Apple computers, software, etc. The case comes out of Apple’s claim that a publisher wrote about a secret, planned product that hadn’t been released yet. The holding turned in part on the definition of "post," as in "post it online."
In the world of digital communications, to "post" is "[t]o send (a message or data) to a mailing list, newsgroup, or other online forum on which it will be displayed; to display or make available online." (a footnote cites to the Oxford English Dictionary, www.dictionary.oed.com, as authority)
The court goes on to use the Oxford English Dictionary (online version, no less) to settle the definition of "magazine," "e-zine," and "periodical."
