This is heavyweight stuff for your bookshelf and serious stuff for your reading. Once in a while, when I could come across a great hardback like this selling for a reasonable price in any used bookshop, I wouldn't hesitate to buy it. This book was bought slightly more than 10 years ago from a bookshop at Coleman Street.
