What are the panel's recommendations for books on design of experiments?
Ideally, books should be still in print or available electronically, although that may not always be feasible. If you feel moved to add a few words on what's so good about the book that would be great too.
Also, aim for one book per answer so that voting can help sort the suggestions.

Best Answer
for me, the best book around is by George Box:
Statistics for Experimenters: Design, Innovation, and Discovery
of course the book by Maxwell and Delaney is also pretty good: Designing Experiments and Analyzing Data: A Model Comparison Perspective, Second Edition
I personally prefer the first, but they are both top quality. They are a little bit expensive, but you can definitely find a cheap earlier edition for sale.
