actual meaning can be found in any online dictionary. And then there's its synonym counterpoise, which ... oh wait, I already did the donut joke! Counterpoise, by the way, is the title of a library review journal for the alternative press, begun by the late Charles Willett in 1997 and now recently defunct. It enjoyed a good fifteen-year run, however, during which time a few of my own book reviews were published there. Poice (for police) turns up only twice in OhioLINK and 25 times in WorldCat, so it should be pretty easy to keep your equilibrium while tracking down and correcting these miscreants in your own library's catalog.
