I bought two books on bench design, the other gets straight to the business of building a specific bench, but Schwarz's book is much more philosophical, almost a "Zen and the art of workbenches", talking about WHY you should need a bench, how it can be specific to the things you want to make , and how to tune it.
Schwarz details two benchtypes and how to build them, the "English" pattern and the Continental" pattern - he then critiques the designs, after his own years of use.
Leavened with a lot of humour and anecdote, and bristling with valuable information -tables of wood hardness and strength, I think this book provides, well, a benchmark in design for anyone wanting to make a really good base for their craft.
