Often, Interaction Design gets lumped in with Interface Design (or simply overlooked). For this I suggest:

"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.

"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 and are often left up to the developers to "figure out".
