I don't know if any customer review could do justice to this encyclopedic work. Its scope is so broad, thorough, scholarly, yet so accessible. Whenever I have a question that simply cannot be answered elsewhere, I turn to the Cambridge Grammar of English Paperback with CD ROM: A Comprehensive Guide and quickly find what I need. I was looking for the One True Grammar Book, a really authoritative tome, something academics themselves turn to for clarification--something technical but not laden with linguistics jargon, something like A Comprehensive Grammar of the English Language by Quirk or The Cambridge Grammar of the English Language by Huddleston. However, I couldn't afford them. Continuing the search, I hit upon this one, and it's turned out to be an invaluable tool. It's indispensable for nonnative English speakers groping for answers to the idiosyncrasies of English, for native English speakers working on the fine points of their mother tongue, and for beleaguered instructors looking for clear explanations with which to help their students. It has satisfied the need for an authoritative guide so much so that I no longer feel that I want the other books. I like the Cambridge Grammar of English's emphasis upon the nuances of spoken English, which seem to befuddle foreign students no matter how much formal grammar they've studied. The book's focus is obviously British-centered English, but it's not all lorries and lifts; 99% of it applies to American English, too. So, if you're on a budget (or not), get this one. England has given us many good things over the years--the Beatles, Dr. Who, Monty Python, and, gratefully, now this!
