Query: good for basics

I do tend to go back to this book whenever Im about to mix some oils or looking for new ones...or even what I want to use based on my mood. I do feel like there's a lot of info that wasnt even tapped into, but this did cover so many subjects, I can just imagine the size it wouldve been if it had went into thorough detail on every topic touched. I did learn a lot from this book.
