The material is arguably good, but the formatting is absolutely horrendous. The worst thing about this book is that it isn't written in Latex. It's probably written in MS Word, which most can agree has asinine handling of equations. Because of this, all of the equations and math syntax is offset from the rest of the text in each line, which makes it really distracting (and irritating) to read. Some of the tables have the header on one page and the data in the next -- again, a significant and egregious formatting issue that was just overlooked or flat-out ignored. Frankly I am surprised the author hasn't changed the formatting after so many different volumes.
