Constituting the largest reference work on Doctor Who ever written, the six-volume About Time strives to become the ultimate reference guide to the world's longest-running science fiction program. Written by Lawrence Miles (Faction Paradox) and long-time sci-fi commentator Tat Wood, About Time focuses on the continuity of Doctor Who (its characters, alien races and the like), but also examines the show as a work of social commentary. In particular, Miles and Wood dissect the politics and social issues that shaped the show during its unprecedented 26-year run (from 1963 to 1989), detailing how the issues of the day influenced this series. As part of this grand opus, About Time 2 examines Doctor Who Seasons 4 to 6 (1966 to 1969) — a massive paradigm shift for the show, as Patrick Troughton takes over the lead role. Among other things, About Time 2 answers such vitally important Who questions as What's the Timeline of the Cybermen?, Whatever Happened to the USA? and Did Sergeant Pepper Know the Doctor?
