Pocket-sized so good for browsing whenever commuting for those who aren't 'phonezombies. Richly informative in a remarkably accessible way - very readable text, wonderfully clear drawings of complex structures, and helpful arrangement of areas of information. I had only a passing interest on acquiring it, but over the years (am here buying a second copy as a gift instead of a risky loan!) have repeatedly rejoiced afresh over it.
