The Robert C. Martin Clean Code Collection consists of two bestselling eBooks:

Clean Code: A Handbook of Agile Software Craftmanship

The Clean Coder: A Code of Conduct for Professional Programmers

In this collection, Robert C. Martin, also known as Uncle Bob, provides a pragmatic method for writing better code from the start. He reveals the disciplines, techniques, tools, and practices that separate software craftsmen from mere 9-to-5 programmers. Within this collection are the tools and methods you need to become a true software professional.

To simplify access to each book, weve appended A to the pages of Clean Code: A Handbook of Agile Software Craftmanship, and B to pages of The Clean Coder: A Code of Conduct for Professional Programmers.This enabled us to produce a single, comprehensive table of contents and dedicated indexes.

We hope you find this collection useful!

First printing, May 2011

Between 1986 and 2000 I worked closely with Jim Newkirk, a colleague from Teradyne. He and I shared a passion for programming and for clean code. We would spend nights, evenings, and weekends together playing with different programming styles and design techniques. We were continually scheming about business ideas. Eventually we formed Object Mentor, Inc., together. I learned many things from Jim as we plied our schemes together. But one of the most important was his attitude of work ethic; it was something I strove to emulate. Jim is a professional. I am proud to have worked with him, and to call him my friend.

Uncle Bob Martin definitely raises the bar with his latest book. He explains his expectation for a professional programmer on management interactions, time management, pressure, on collaboration, and on the choice of tools to use. Beyond TDD and ATDD, Martin explains what every programmer who considers him- or herself a professional not only needs to know, but also needs to follow in order to make the young profession of software development grow.

Some technical books inspire and teach; some delight and amuse. Rarely does a technical book do all four of these things. Robert Martins always have for me and The Clean Coder is no exception. Read, learn, and live the lessons in this book and you can accurately call yourself a software professional.
