I have been studying and practicing design patterns ever since I ran across an early draft of GoF's Design Patterns book at Computer Literacy bookstore almost nine years ago.  I also enjoyed and continue to get mileage out of Martin Fowler's Refactoring book.  Today, thanks to ScottW, I found Joshua Kerievsky's Refactoring to Patterns, a growing body of work showing how to use design patterns in refactoring.  I suspect the work will continue to grow into an excellent book.  Read it now (750k PDF) and buy the book when its published.
