Abstract
Reading Anthony Gregory's massive tome on the development of habeas corpus from fourteenth century England through its incorporation into Common Law, and then into Article One of the US Constitution and finally, down to the Patriot Act and other more recent modifications of the “great writ,” I am reminded of something that I heard as a graduate student many decades ago, when I asked a professor about reading a particularly demanding book. I was urged to plunge into that text, providing I could spare a few months. Unlike the book I asked about then, which was a total waste of time (as I soon discovered), Gregory's study is a monument to meticulous research.
