I use beginner and intermediate as board terms as kind of a cop out :) Intermediate could be from 1400-1800 
The ones under classics are classics and you can't go wrong with them even if I didn't "+" them. I also like anything written by Silman, but so do other's, he's highly regarded and his reassess books are sure to become classics, you can't go wrong with him either. Any book out of Seriwan's winning chess series is also great for beginners/advanced beginners.
I'm sure other people can name more, these are just some good ones I know about.
A "+" means I personally really like the book and would recommend it... err, not that I don't recommend the others, it just means I'm bias toward that particular one :)
