Martijn van Welie has a very comprehenisve list of Design Patterns for Interaction Design. His list is very well organized into categories ranging from e-Commerce to navigation to searching.
He claims that he is more of a curator for information regarding interaction design, but as far as I’m concerned the overall structure and amazingly complete range of resources that you’ll find on this website represents a contribution to the subject that is worthy unto itself. This is a great starting point for anyone who is interested in interaction design and is definitely worth a bookmark. Even if your interest is peripheral, van Welie’s presentation makes learning a pleasure here.
