How to Use Commentaries to Improve Your Research

I've got more than a shelf per book in the New Testament. And probably at least half a shelf of all the less major books in the Old Testament. How do you, how do you use commentary as well? Let me just put it that way. It depends on the size of the text you're using. I don't necessarily read everything in the commentary. Just skim the section and just read what I'm trying to understand the section.
