The Daniel Jones English Pronouncing Dictionary, so well known in the EFL teaching world as to need only to be referred to simply as "the EPD" or even simply "Jones", was first published in 1917. J. M. Dent, its original publishers, repeatedly hyped as new "editions" various quite minor revisions but not, one may be sure, at the instance of Jones himself. In its heyday, in the two or three postwar decades, it had a remarkably wide circulation for a relatively specialist publication though by the eighties its popularity had waned a good deal. Not long after the appearance in 1990 of the remarkable 800-page Longman Pronunciation Dictionary by J. C. Wells (hereafter "LPD"), Cambridge University Press acquired the copyright of the EPD. The present long-awaited 15th edition of "Jones" is most certainly a major revision, indeed the most fundamental in its whole history. It has been much enlarged so that it now has "over 18,000 new entries", and although it has a similar number of pages, they are 3cm taller and more than 2cm wider. The principal architect of this very ambitious re-working of the EPD has been Professor Peter Roach of Reading University.
