We are keen to hear from anyone who has material recorded off-air that may not exist in official archives that would be of interest to Doctor Who fans and posterity, which we could include in future DVDs. Without help from a few fans in the past, we would not have had items on the DVDs such as any of the 'Swap Shop', 'Pebble Mill' or 'Nationwide' interviews, BSB interview segments, trailers and continuity announcements. Although we have access to a large number of items, coverage remains patchy. We are sure that there are many clips out there which we do not have, or which are in better quality than our current holdings. We want to avoid the situation where, after a DVD is released, someone approaches us with a better copy of something, or extra material which could have improved the release.

With exclusive photographs, concept drawings, diagrams and FX models, and written by Justin Richards, this will be a lavishly illustrated collection of the scariest monsters from Doctor Who - a follow-up book to the best-selling Aliens and Enemies and Monsters and Villains.

Doctor Who: Creatures and Demons will be published by BBC Books on May 10, 2007.
