Spoilers are precisely defined here. Rules vary by the story's medium. Info from television stories can't be added here until after the top or bottom of the hour, British time, closest to the end credits roll on BBC One. Therefore, fans in the Americas who are sensitive to spoilers should avoid Tardis on Sundays until they've seen the episode.
The Dalek Tapes appear reprinted in this issue with heavily edited opening and closing captions.

This is the first time two Doctors have featured on the front cover.
Published every Thursday, this issue had a cover price of 12p (UK).
