List of books for Software Architecture related to Design Patterns

While browsing the Boston Flash Platform Group. I found a reply from the LA Flash Platform group that had suggested their list of books for software architecture in the context of Design Patterns. Yes these guys have a user group and actively discuss the application of Design Patterns for the Flash Platform.
And they even have Brightcove host the next meeting. Can you imagine what it would be to have the opportunity to be a part of such group...
I wonder why we have not tried to create such a group in Bulgaria so far. Is it because no one in the Bulgarian Flash Community does not use Design Patterns in their projects or just because Bulgarians don't like to share their know how :)
Let me know if there is anyone interested in such a discussion?

The list of books:
Refactoring to Patterns (The Addison-Wesley Signature Series) (Hardcover)

Refactoring: Improving the Design of Existing Code

Patterns of Enterprise Application Architecture

Pattern-Oriented Software Architecture Volume 2: Patterns for Concurrent and Networked Objects
