About Time 9: The Unauthorized Guide to Doctor Who (Series 4, the 2009 Specials)
In About Time, the whole of Doctor Who is examined through the lens of the real-world social and political changes as well as ongoing developments in television production that influenced the series in ways big and small over the course of a generation. Volume 9 of this series finishes out the revamped Doctor Who starring David Tennant, covering Series 4, the 2009 Specials and extras such as the animated story Dreamland.
Tat Wood
Since the far-off days of About Time 7, when most people were reasonably sure what number came immediately before 9, Tat Wood has been working further About Time installments and totally non-Doctor-Who-related works (one of which, World History in Minutes, is available through Quercus Books and all good remaindered book shops).
