'The appearance of these handsome volumes represents an important achievement, or, more accurately, several important achievements. The standard of the diverse entries is high - meriting praise all around for the editors and contributors. The production quality is high, auguring well for the Press - as does, most especially, the simultaneous appearance of Welsh and English editions. For the weighty and colourful item that it is, GBP65.00 is good value. With the successful products now in hand, the kicking of the publication date ahead into 2008 is vindicated as a triumph of standards and uncut corners over the distortions and compromises to which many at UK universities and university presses succumbed in the race to the 2007 Research Assessment Exercise.'John T.
