The book covers a breadth of information, as you would expect. It's concise and easy to follow. I would suggest this book to anyone who wants, or needs, to write in a grammatically correct, and unambiguous syntax.
Interestingly, the punctuations (comma, colon, semi-colon etc.) are listed together, alphabetically, in the section 'stops', which makes it easier to make comparisons, between different punctuation marks.
One issue I have, and the reason that it is not five stars, in some areas it is not as clear, or concise, as it might be, which requires comparisons between examples.
PS The typeface in my re-issue is very easy to read, which could explain the readability that I have experienced compared to people with different versions.
