When it rains, it pours™...books

In the continuing stream of boutique and niche histories, the man who brought us Cod: A Biography of the Fish that Changed the World has just published a new book, Salt: A World History, that I spied today in a Gloucester bookshop. Salt played a role in so many parts of human civilisation that it is terribly ambitious to do a complete world history of the substance but, since Cod was so well done I'm sure the author does a reasonable job.
