I'm new to TES and I think thr more info the better, because in only 15 hours of pkaytime ive run into stuff I don't fully understand, and with 650 pages, at the very least I have something interesting to thumb through, plus I Google search for things I get stuck on anyway, so I think having a physical book giving me hints would be helpful.
I wouldn't use it for spoilers or as a crutch- just the tricky parts that I am completely lost on, or to get some helpful insight on something I might not understand, particularly alchemy and enchanting.

You won't regret it.
