The new, eighth edition of Gimson's Pronunciation of English by Alan Cruttenden is available now.
One of the eye-catchers will certainly be the replacement of RP (= Received Pronunciation) by the more neutral term GB (= General British). The latter was first mentioned in an academic publication by Jack Windsor Lewis in his 1972 book A Concise Pronouncing Dictionary of British and American English:
It took more than 40 years for the term GB to appear in another important book on the topic.
The reason why Cruttenden adopted GB as a term is summarised on p. 80, where he states that it was because of the "narrow use by many of the name RP, and the frequent hostility to it, the accent described in this book has been changed to General British (GB)." He then adds that "it has to be made clear that [...] it is not a different accent that is being described, but an evolved and evolving version of the same accent under a different name."
