What are the best resources for Windows Workflow Foundation (WF)? [closed]

I am looking for a few books, blogs or articles on WWF. I've read the books below; however, I need resources that cover the topic in more depth. I am especially interested in local services, persistence, tracking and viewing Workflows from a website. Any suggestions??

IMHO, the best books are Essential Windows Workflow Foundation and Programming Windows Workflow Foundation: Practical WF Techniques and Examples using XAML and C#.
