If English is not your mother tongue this is a perfect reference source for you. Almost each entry contains extensive usage notes and many examples of usage, usage that sometimes goes back to 16th century.
The dictionary consistently pays attention to British and American differences; frequently a brief summary is given for the reader at the end of entry.
Various commentators are quoted, both British and American (Burchfield, Garner, Fowler to mention only a few) their views are often compared to/with Merriam Webster sources and sometimes their opinions are divergent.
Excellent as far as irregular verbs usage, very helpful with less frequent prepositions (prefer over) (expert at)
Sometimes however, the dictionary fails to provide any usage notes.
If you want to check what prepositions collocate with bored or crave you will not find it there alas...
All in all, the dictionary has two main flaws: Too historical approach to English usage as well as lack of CD, which would make browsing much more challenging...
Still,if you are a dictionary freak, this is definitely something you must have!
Great book which is almost unusable in Kindle form. Kindle software is for novels, so it always thinks you want to go to the last page you were reading - not true of a dictionary. Really hard work as a reference book, almost acceptable as a special interest book to read from front to back. Come on Amazon, it can't be that hard to create a Kindle reference Reader...??
Never patronizing and always richly descriptive - as a solid reference book should be - this guide to (US) English usage should become one of your best desk buddies whether you're interested in writing, translating or simply wanting to learn how to use English more accurately.
