Many people have been generous with their time and knowledge to point out errors or suggest amendments to the first three published versions of the Companion. The present revisers stand infinitely in their debt. Without identifying any one individual for a greater or lesser contribution, they include: Claudia Alarcon, Carol Bloom, Jennifer Brennan, David Burnett, David Burton, Martin Caraher, Elizabeth Carter, Kate Chynoweth, Caroline Davidson, Fuschia Dunlop, Carol Field, Simon Franklin, Helen Caruana Galizia, Louis Glowinski, Ralph Hancock, Richard Hosking, Cecil Hourani, Dan Hughes, Philip Iddison, Mary Isin, Ian Jackson, Jozef Jedinak, Maria Kaneva-Johnson, Anneke Karsten, Martina Kortisova, Tim Lang, Paul Levy, Elisabeth Luard, Avril MacLennan, Mike Morony, Michael Noonan, Sandra Oliver, Roger and Sri Owen, Clare Parker, Charles Perry, David Potter, William Rubel, Rosemary Stark, Barbara Wheaton, and Mary Williamson. Others, we are sure, have played their parts in this process of revision, not least those many public reviewers whose observations have not, we hope, been disregarded. Our thanks are due to them, and any others who inadvertently are not named here.
