Passing by one of my favorite sites, smashingmagazine.com, I noticed a nice post for a listing on Web Development books. Most of these are the inspiration of many well known, professional web designers and developers. The list includes CSS scripting, color theory, logo design, typography,web standards, etc. One book for web navigation/layout was the book called "Don't Make Me Think" by Steve Krug.
