The NEC Handbook is far more informative and easier to understand than the Code Book.
Add uneforcable to the list as well.
I'm not saying I don't own the handbook...I have one at the office, the electronic version on both of my computers and the McGraw-Hills handbook in my home office.
When I teach, however, it is nothing but the NEC, because that is the only document that matters for enforcement and determining bare bones compliance.
