Not often does a newspaper of The Times' eminence publish its in-house style and usage guide. (Writers of 1976 last saw an edition of this book.) This guide gives students, teachers and professionals the tools to write well. I have found many usage notes that I did not previously know.
I found that this book borders on being a tad too politically correct.
It doesn't reach the point of crossing this border, but it does come close. It insists that people call cripples a people who have lost the use of their legs.
Also, this book could have included a few more grammar terms that the average person would not know. There are too many terms that the average educated person knows, like when to use "a/an." What the book could have summed up in two sentences encompassed almost a page. Conversely, what should have taken up a page, the book treated in a few sentences.
Further, it seems like the book purposely omitted esoteric newspaper terms that would be found in the in-house edition found at The Times' headquarters at 229 West 43rd. I'd really like to have read about the various font sizes and columns and the like. But the authors decided for me that I was apt not to be interested in reading about that arcanca.
Otherwise, this book is an enjoyable read. BUY IT, STUDY IT! (You should also buy Stunk's and White's The Elements of Style, also available for purchase here on Amazon.com)
