Summary: Excellent book if you are a law student. With a little bit of imagination it likely also works for those that are reading a standard piece or type of material for a particular purpose.
NOTE: This review is written from the perspective of my interest in learning all that has been known about speed reading in preparation for making a speed reading course. I naturally learned to speed read, i.e. tested around 2500wpm vs. the average Native English speed of 150-250wpm and average college educated speeds of 300, and this was recommended by my partner in crime on the course, a person who has been studying and teaches this topic.
If you are reading this book to understand how to read faster or to research speed reading, I would say that you might want to read The Psychology of Reading first. It has more details on what reading actually is. However, if you wanted to expand on how to read faster, via purposeful reading, the manner in which this book considers the topic is quite good.
In Part 1 - She makes the case the for why reading will advance one's law career. she talks about the relationship between reading and thinking for the law school student. This is an easy audience and some might think it unnecessary. However, I think her point here, even more than the speed readers is that speed reading is an exercise in comprehension more than actual speed. As you get faster, you could start to give up some of this if you haven't really trained yourself to think about speed-reading correctly. A lawyer might have a stack of cases that MUST be read. How does one even approach the exercise as far as goals given their current ability.
McKinney has broken up the various types of reading that one might see as a law student expertly. She then provides questions one could ask themselves while reading. Her ideas here are two fold. First that one might be reading slowly b/c they are not fully engaged. Second the difficulty with being fully engaged might be one of needed to think through what engagement is, i.e. the questions that are relevant. My analogy for this is as follows: It's a little bit like, if you go to Disney World, yes you saw everything, but I want to point your limited attention to X,Y,Z. To me this is very important. So many that focus on comprehension think that you should take every single nugget out of a piece. That's insane. That's like going to Disney World and swearing that you saw every single item. But it's also not true if you spent a day in the Magic Kingdom that you didn't go there at all, or that you didn't experience it in a meaningful way. McKinney's point is that given you've got to get through the material with limited time and that the overview of multiple cases is necessary, if you've got to make choices, let's make sure you see come out of the exercise with a specific set of knowledge. I love it.
The last part of Part II Review, Rephrase, and Record is about active reading and while directed toward Law Students isn't so different from what I do (very reassuring). There's more science to it, which is in the previous book I mentioned. But the point is, if you're going to fly by the material because your career deems it necessary or just because you prefer to speed read, then take a moment and absorb the information. The ways to do it are - Take Notes, really think about what you're reading by writing a brief (or a goodreads summary, etc). I can attest, at least personally, this really does work.
Part III will likely be seen to the person who is still acquiring this skill as superfluous. For her audience, law students, the focus is reading law school case law. However, this next section is how to approach reading statutes and cases on cases. The former has a particular format and approach that can be at first quite difficult to approach. The latter seems excessive. This is particularly because it is uncurated. She walks you through it and how to think critically while reading it.
I would say that every industry has this type of material. If you fail to read it, your arguments and discourse about a topic are more basic. You fail to even understand the point of view of the person that you are talking to. Moreover, for those that are more familiar with the art of speed reading, greater familiarity, more instances of reading in a topic make you faster. If you've been to Disney already once, you will be able to find your way around faster the second time and with greater knowledge of what to avoid and what to spend more time on. I wish she would have said that explicitly, but I think she's got what is needed here (or if she said it upfront, I may have missed it).
I would not skip the appendix. There are a lot of great things there for those picking up the craft.
