I must say this was, to me, an extremely useful book. Much more than anticipated. I thought I was a quick reader before, but thanks to the excercises in this book, I managed to increase my speed by another 20% on average.
Yes, it is lengthy, but it really takes you step by step, giving good guidance and excercises. And even though it was originally written in 1944 (I read the 1958 completly revised 3rd edition), it is far from antiquated. In fact, apart from the obviously dated selection of articles for the reading excercises, the whole was fairly modern.

e.g. p 348 At the beginning of the section about reading critically, the author states that every writer wants to convince the reader of his philosophy, attitude, POV. Even in fiction, a writer is a "special pleader." He continues:
"And, of course, it is almost impossible to pick up a magazine or newspaper today without being bombarded by special pleading. As you turn the pages, almost every writer is saying to you, directly or by implication, "This si what I think; or, This is how I feel; or, This is how I interpret a situation; or, These are the conclusions I draw from the (selected) facts; This is how I solve a problem; or, This is how to do the job; or, This is how I react to what has happened; or, This is how you should react; or, this is the furniture, clothing, perfume, cereal, book, soap, cigarette, automobile, or liquor you should buy, the transportation you should use, the play or motion picture you should see, the vacation you should take, or the charity you should contribute to"; and so on and on, in endless, infinite variety."
And this was written way before the social media age.
Yes, the author uses lengthy sentences at times (and here it serves its purpose), but it is worth the effort.

I also appreciated the author´s thoughts about why to read (both for furthering education, as well as entertainment), and in the chapter about skipping and skimming (which in my opinion is sacrilige), he made an appealing case, and argued that these techniques should be used sparsely, if at all.

So, all in all, yes, these almost 400 pages take a while to get through (ironically), it is worth the effort, in my opinion. ( )

It's a simple message. Read more. Read widely. Be alert. Set a goal. I only read the suggestions. It was nothing new. If you want to be good at it, you just have to practice. That means reading a lot in many different areas. ( )
