A paragraph from this book showed up in my Google search results. Just in that paragraph, there were two factual errors.
(Full disclosure: the paragraph was about beer. Perhaps you don't care about beer and would prefer to take your chances. It doesn't bode well for the accuracy of the rest of the book though.)
