Don't listen to the reviewer who purports to give Zerby 0 stars, that review isn't worth your while. Try this, instead: I'm trying to delve into the study of footnotes (non-scholarly). Grafton's work relies too heavily on scholarly use. Kevin Jackson's Invisible Forms only lends the footnote a chapter. So Zerby, as of now, is the happy medium. And yes, he rambles. Yes, the book weaves in and out of direction. But that's the point, and assuming you'd encounter otherwise is somewhat deluded. If you accept Zerby's offering for what it is, and roll with the punches the book provides, you might learn a thing or two about how the footnote has evolved (AND discover a few interesting original sources to peruse later)!
