Context:
Doctor Who books have been published from the mid-sixties through to the present day. From 1965 to 1991 the books published were primarily novelised adaptations of broadcast episodes; beginning in 1991 an extensive line of original fiction was launched, the Virgin New Adventures and Virgin Missing Adventures. Since the relaunch of the programme in 2005, a new range of novels have been published by BBC Books. Numerous non-fiction books about the series, including guidebooks and critical studies, have also been published, and a dedicated Doctor Who Magazine with newsstand circulation has been published regularly since 1979. This is published by Panini, as is the Doctor Who Adventures magazine for younger fans.
