Extreme Programming Planning
By Kent Beck and Martin Fowler (2000)
"XP is the most important movement in our field today. I predict that it will be as essential to the present generation as the S.E.I. and its Capability Maturity Model were to the last." --From the foreword by Tom DeMarco

Extreme Programming Installed
By Ron Jeffries, Ann Anderson, Chet Hendrickson (2000)
Explains the core principles of Extreme Programming and details each step of the development cycle. Teaches readers how to work with an on-site customer, define requirements with user stories, estimate the time and cost of each story, and perform constant integration and frequent iterations.

Refactoring: Improving the Design of Existing Code
By Martin Fowler, Kent Beck, John Brant, William Opdyke, Don Roberts (1999)
This book enumerates a suite of operations that allow developers to make many minor changes to their software in a disciplined and methodical manner. The goal of these changes is to move the software into a shape that is better able to survive the rigors of its lifecycle. Though the catalog of refactorings, and the examples of how to apply them, are invaluable; the real pearls in this book are the nuggets of pragmatic attitude and hard bitten advice that the authors convey to the reader. One of the most important books of 1999.
