Cox had unrivaled breadth across the statistical books that he authored, and I'm far from an expert on his catalog, but I have read three and they are excellent. - Theory of Design of Experiments is an excellent and non-technical book on experimentation and data collection. Still important in an era of big data! - Analysis of Survival Data is the book on the Cox model. It is quite technical. I own this book for historical reasons, and I'm glad I read it, but I now recommend Therneau for serious survival statistics. - Theoretical Statistics w/ Hinkley is still a great mathematical statistics book. Excellent math-stats books are uncommon now, and Cox was a master. Cox also wrote a few books on stochastic processes that are well regarded, but I'm unfamiliar. I most recently read Celebrating Statistics: Papers in honour of Sir David Cox on his 80th birthday which is a very thoughtful collection.
