What is the difference between the various optional Oxford dictionary add-ons?
The Oxford Dictionary of English (ODE) is a large single-volume dictionary, currently the 3rd edition, with pronunciations in standard British (BBC) English. The Shorter Oxford English Dictionary (SOED) is a two-volume dictionary (6th edition) in small print, and contains a third of the content of the full 20-volume Oxford English Dictionary (OED). SOED is significantly more comprehensive than ODE (and arranged historically), though a few years older, and also comes with audio. The New Oxford American Dictionary (NOAD) is a single-volume dictionary very similar in scope to the ODE, but with North American pronunciations and a more American focus.
