The book How to Read a Book (by Mortimer Adler) goes into some detail about the levels of reading (skimming, full reading, analytical, and syntopical) and attention that should be paid to books, and describes good technique for quickly skimming a book to determine what it says, how well it makes its point, and whether more careful reading is needed.

Yeah, I have actually read that book. But he doesn’t say you can learn a lot by reading like this. In fact he says that a book should be read twice, second time soon after finishing it the first time.
