The following books and references can provide you with a deeper look at the ISO 9001:2000 Standard:
ISO 9001: 2000 for Small Businesses by Ray Tricker (Butterworth-Heinemann)
This book focuses on the implementation and use of 9001 in small businesses. The focus is on using ISO 9001 in a way that reflects the objectives and directives of your organization without moving into the realm of developing heavy or cumbersome policies and processes. The book also helps you if your organization is migrating from the 1994 Standard. It describes many of the additions, changes, and differences you should consider when making the move up.
ISO 9001, The Standard Interpretation by Leland R. Beaumont (ISO Easy)
Beaumont's book focuses mainly on the differences between the 2000 Standard and the 1994 Standard. But it also contains a pretty complete explanation of what you should understand and appreciate about ISO 9001, especially if you're new to this specification. The book is written in a casual, friendly style, with good side-by-side explanations of all sections of the Standard. It may not be the most exhaustive work on ISO, but it makes for a good introductory or exploratory look.
ISO 9001:2000 for Software and Systems Providers: An Engineering Approach by Robert Bamford (CRC)
Because ISO 9001 is known as a generic standard, it can realistically be applied to just about any manufacturing environment: toothbrushes to missiles. This book focuses on application in technology environments, and in doing that, you can garner a good comparative picture of what ISO offers compared to programs like CMMI and Six Sigma. The book's approach is comprehensive and thorough. Because it focuses on considerations of engineering shops, it can at times get a little technical. But it's the kind of detail technical people will appreciate. And the general recommendations are appropriate enough for the typical process improvement audience.
Systematic Process Improvement Using ISO 9001:2000 and CMMI by Boris Mutafelija and Harvey Stromberg (Artech House Publishers)
A lot of the value of this book comes from two angles. First is its very thorough approach to discussing the role of ISO 9001 in the realm of rigorous process improvement. Second is its inclusion of CMMI as a potential partner for ISO-based solutions. The authors do a good job of explaining how a CMMI program can comfortably fit under the larger umbrella of ISO. They also present good explanations of the reach and scope such a program might include. This is a solid resource for technology shops that want to understand not only the values of process improvement, but how these two standards might be harnessed to pull together effectively.
ISO 9001:2000 Explained by Charles A. Cianfrani et al. (ASQ Quality Press)
This is a good book to turn to if you'd like a dedicated and complete presentation of the scope, purpose, and structure of the 9001 Standard. Cianfrani describes the sections and requirements of the Standard and combines this with explanations of how typical implementations are accounted for. The focus of this book is not on any one industry sector. And so it maintains a generic approach that supports the generic purpose of the Standard. A good general reference.
