The Classic British Telefantasy Guide is derived from the second edition of The Guinness Book of Classic British TV with various corrections and a revised introduction to bring it up to date. It was written when the Internet barely existed, and at a time when few books had been published on the subject. This is, however, by no means a new or completely revised version of the original material - too much time has passed, and if we were to start reworking and correcting the text now, it would probably never be finished! Instead, Classic British Telefantasy is an electronic reprint of some of the authors' earliest work, repacked for a new format and, perhaps, a new age.
