I'm actively reading with pencil and paper, just like I did back in school, learning new things. Sometimes I review old stuff or get other books on topics I already know. In my opinion, if you have only one book on a particular topic that you're "supposed to know" in your area of expertise, then you could be missing out on something that another author might cover, or another author could cover better, if it's information you learned in another author's book. I've got a pretty big personal library. I like to have at least three books on the various topics that I'm "supposed to know" as a mathematician. On stuff I really enjoy, I tend to have more. I have six Differential Equations books, and believe it or not, they're not all the same (differential equations is a pretty active area of research), whereas I have three Calculus books, and they pretty much say the same thing between all three of them (Calculus hasn't changed in over 200 years), although they present things differently in their layouts. I also have Physics books, various types of engineering books, and a bunch of computer programming books, mostly in the C family of languages (C, C++, C#), although I do dabble in Python and R as well.
Believe it or not, I have a bunch of investing/trading books, except they all seem to say the same thing, if they're any good.
