The Official Doctionary

 was a novel written by Justin Richards aimed at the younger reader with short paragraphs on a range of topic that are organised under various categories written from the viewpoint of the Eleventh Doctor referencing the more recent years of Doctor Who, from Rose 2005 up to The Big Bang in 2012.

Publisher's summary
The Doctor likes to talk. A lot. About anything and everything and frequently about things that make no sense to mere human brains. Here he explains some of the trickier concepts of time, space, Time Lord technology and the mysteries of the universe. This Doctor's dictionary is invaluable for budding time travellers and intergalactic companions.
