Book excerpt: All of time and space...where do you want to start? Governed by Time Lord technology, the TARDIS Type Forty is the most powerful craft in the universe and this comprehensive fully illustrated manual holds the key to its operation. The appearance of the Doctor's TARDIS, both inside and out, has changed many times over the years, and this manual features every incarnation – including the latest version for the Thirteenth Doctor. The manual covers the console with fully labelled detailed schematic diagrams for each function, the ship’s famous chameleon circuit, as well as floorplans, specifics of dematerialisation, the use of force fields and tractor beams and much more. Complete with case studies of the wonder-craft in action, taken from the TARDIS’s many trips through space and time, this manual is an essential guide to the wonders of the Whoniverse.
