While wandering through Google Books, I ran across these limited previews of these three FDA GMP-related books. I thought you might be interested. Although the previews are limited, there's certainly enough content that can be read for learning, and plenty to review if you're considering buying the book.
Interpretation of FDA's Quality System Regulations (QSR) With QSIT references By Medical Device School (Google books preview)
The FDA and Worldwide Quality System Requirements Guidebook for Medical Devices (Google books preview)
Buy the book: The FDA and Worldwide Quality System Requirements Guidebook for Medical Devices, Second Edition
