Query: Great for easy and detailed reference of everything in Photoshop Menus/Tools

I found this a great book to go over and learn everything on how this program works (and lots of stuff that most training books don't cover). Now true, I and others find it difficult to use as purely a training manual (I like projects to learn from) and this provides no projects. But after completing my How To Use Illustrator AND Photoshop books, I got this book to go through and have a real understanding of the menu's and for easy and quick reference if I can't figure out how to do something. So I highly recomend it for that reason alone. As for learning the programs from the ground up...depends on your learning style.
