This slim volume, for ages, was pretty much the Doctor Who 'Bible'. It had all the information about the Doctor, which, to be frank, wasn't much. But it did have nice big pictures of his enemies, which was nice. The only other reference work available, with an episode guide, was 1973's BBC Doctor Who Tenth Anniversary special. Seems odd, nowadays, but that's how things were.

These are 'novelisations' of the TV stories. Written, ostensibly for children, they are definitely a good read. They usually contain lots of back story, and a good few are of stories that the BBC 'lost' or junked in the 1970's and 80's, and so are the only way to enjoy those serials. Eventually, every 'classic' Doctor Who story was novelised, except for a couple written by the late, very great, Douglas Adams. The ones above were the first of over a hundred or so. They are, left to right, top to bottom: The Sea Devils; The Auton Invasion; The Cybermen; The Doomsday Weapon; The Abominable Snowmen; The Curse Of Peladon; Day Of The Daleks; The Daleks; Terror Of The Autons; The Green Death; Planet Of The Spiders; The Giant Robot; The Loch Ness Monster; The Three Doctors; The Tenth Planet; The Dinosaur Invasion.
