The purpose of this talk is to relate the author's experiences encountered in starting to use Mathematica to download, preprocess, edit, and (ideally) ultimately analyze written material appearing on the Web.  The specific topic chosen as an example is a very interesting (and controversial) book written by Gary Taubes and entitled "Good Calories, Bad Calories."
