Universal Principles of Design
I picked up a copy of Universal Principles of Design when I was in London for the Symphony Symposium in June of 2010.
125 Ways to Enhance Usability, Influence Perception, Increase Appeal, Make Better Design Decisions, and Teach through Design
Universal Principles of Design, Revised and Updated is a comprehensive, cross-disciplinary encyclopedia covering 125 laws, guidelines, human biases, and general considerations important to successful design. Richly illustrated and easy to navigate, it pairs clear explanations of every design concept with visual examples of the ideas applied in practice. From the 80/20 Rule to the Weakest Link, every major design concept is defined and illustrated.
