Best web design books 2014/2015 [on hold]

I'm starting to study web design, and i'm looking for some books about this area. Since i'm a web developer for almost 8 years, my real interest is not only about HTML and CSS (Which i already have some pretty good knowledge), i'm most interested about the concepts of web design, things like:

• Pre-production.


• Production.


• Layout.


• User experience.


• Proportion and aesthetics.


• Color harmony and theory.


• Visual communication.


• Images.


• Typography.


• Navigation.

I don't believe that there is a single book that could really cover all this contents, so feel free to provide more that one!

Thanks.

PS: The only web design book that i read so far was Head First Web Design (And it was really basic).
