I'm a mature student of linguistics and English with seven English dictionaries, including two copies of this works earlier edition, a smaller Oxford, a large Webster's and a facsimile edition of Jonson's original dictionary. This dictionary is the one that gets used the most.
For many years I swore by the earlier edition and this new one improves it with a newer selection of words and the thumb indexes for each letter making it a little quicker to find the word you need.
For a student of lexicography this dictionary is unmistakably an Oxford while moving towards a more modern world. While the pronunciation is the good old southern received from the original OED they have moved to the International Phonetic Alphabet from the one developed for the first OED. The layout and typeface for entries are still the same; easily read and well laid out. They keep the same marvelous information regarding derivation of a word but replace a definitive date for earliest use with a symbol that places it in the first second or final third of a century, probably more honest anyway. Like the earlier Shorter Oxford most entries also have usage examples for the word, many offer a usage for each sense of the headword.
While the word choice among the 100,000 or so headwords in these two volumes has some holes they are not large at all and mostly confined to more particular areas that border on jargon or industry specific terms. Like some other reviewers I can bemoan the absence of words in my particular topics of interest but there is no point, almost all people will never notice their absence.
For most of the English speaking world this is the dictionary that all high school and university students should own, the perfect answer for most of us who cannot afford or house the definitive Oxford English Dictionary. OK, it may be fairly costly but a dictionary this good is purchased once a lifetime and one this large will not be lost at school or be left at the bus stop. My family has had an earlier edition for thirty years.
Argument can perhaps be made that within the US, with its more Elizabethan spelling, a home grown dictionary such as Webster's should perhaps be recommended, since the Shorter Oxford lists US spellings and notes where they are the prevalent US spelling I would disagree.
I would recommend this dictionary to everyone who speaks the English language. Every home deserves a copy of this dictionary.
