Ian Mayes is the Guardian's readers' editor. This selection from the 350 or so Open Door columns he has written in the past decade offers a unique and frank insight into the internal working and decision-making processes of one of the world's great newspapers. They cover a period in which, through its multi-award-winning website, the Guardian has become a truly global publisher. Through this widely influential column, readers have been able to subject the Guardian's journalism to close - and public - scrutiny and to listen in as their observations and complaints are discussed by the journalists. The columns provide a running debate on ethical issues, they explain how the paper works - and occasionally they discuss the Guardian's use and abuse of the English language. It is a book that will open the door to what is still for many a mystifying world. At the same time, it will transmit to students of journalism the enthusiasm for the craft that has carried Mayes through a career spanning half a century.
