Does it count as "reading the book"? Yes, I studied the grammar and went over the main 201 verbs and glanced at (and still use pretty regularly) the more comprehensive verb list at the end, but I am not sure whether this kind of a publication is really there to be "read". :)
That said, I find the quaint discussion of changing Swedish grammar (written in the early 1970s, I believe) quite interesting in light of these changes having, by now, pretty much taken over the spoken language.
