Tufte books are awesome, but overkill for website UI.

"Defensive Design for the Web: How to improve error messages, help, forms, and other crisis points" by 37 Signals (2004) • Error management (not just 404s) is one of the most overlooked UI portions of a web project

"Submit Now: Designing Persuasive Web Sites" by Andrew Chak (2003) • Similar to "Don't Make me Think", but focuses more on personal interaction & choices more than layout.
