Order this book from your preferred supplier. My preferred option is obviously Powells.
I spent many Saturdays in this shop while living in Portland, Oregon. It's like Amazon, except that when you get to Portland and decide to visit their store, you will find yourself in a paradise of books - one square block's worth. You can rifle all the books and lose yourself in your favorite subject. Potty training? Mathematical algorithms? Surrogacy?
Having lived in Oregon for six years, I still love Portland and Eugene, If you have no preference, when you get to this page, choose Powells.
