My library on fire!
Panic, consider suicide, worry if my insurance will cover it, then run in to get...
The World Atlas of Golf as its such a wonderfully complete book. Coffee table aesthetics combined with great essays. No wait, A Round of Golf Courses by Patric Dickinson as mentioned earlier by Sean Arble. Such a wonderful little book. No wait, too many to choose... so finally decide on Tom Doak's Anatomy... as it was a gift from a good friend and is signed by the author.
Cheers,
James
