I also tell them several other things about the book. First, this is not just some handbook that secretaries can use to look up how to format a letter. It is an authoritative reference for all aspects of writing English. It should be next to the dictionary and thesaurus on the shelf of everyone who needs to write at work, from clerks to executives. Second, if your boss or anyone else argues with you about any rule of writing, you only have to point to the relevant entry in this book. All arguments stop there. Third, the size of the book is deceptive. It uses small font and thin paper. With normal font and paper, it would be the size of two or three large dictionaries. That's how much useful stuff is packed in this book.

It takes a while to get used to how the information in the book is formatted, but it is well worth the effort. All entries in the index include page numbers as well as topic numbers, which they call "rules." The book is logically structured around these rules, and it makes related topics easy to find.

I rated this book 5 stars because I think it is superior in all categories for a reference book: comprehensive content, abundant examples, thorough index, authoritative author, and reasonable price.
