We also received valuable comments from Bengt Altenberg and Gunnel Tottie, who read draft versions of individual chapters. (Bengt's online ICAME Bibliography also provided us with an extremely useful starting point for our own Bibliography.) At a later stage, pre-final draft chapters were presented to the Longman Linglex Advisory Committee, where again a strong impetus to improve the book's content and presentation was provided by valuable and (often) trenchant critiques from a group of leading British linguists, under the chairmanship of Lord Quirk: Rod Rotitho, Gillian Brown, David Crystal, Philip Scholfield, Katie Wales, John Wells, and Yorick Wilks.
