Great XP|Agile book for free download
Agileskills.org has a great book for free download as a pdf. I flipped through the first chapter which has a quick intro to refactoring to remove duplicate code. The following chapters get a bit tougher I’m sure. What I really like about this pdf book is the extensive code examples. Not just little snippets and then solutions such as “create another class with blah..”. They actually show complete class listings with the differences in bold. Great for learning.
You can download the entire book or individual chapters.
