Past Doctor Adventures
The Past Doctor Adventures (sometimes known by the abbreviation PDA or PDAs) were a series of spin-off novels based on the long running BBC science fiction television series Doctor Who and published under the BBC Books imprint.Instead, they opted to publish their own range beginning in 1997 with The Devil Goblins from Neptune by Martin Day and Keith Topping.These were also inherited from Virgin, a version of their Decalog short story collections, and when the BBC ceased publishing them, a licence to continue was sought by Big Finish Productions, who continued to publish their own range of Short Trips collections until 2009.The BBC Past Doctor paperback series continued for the remainder of 2005, but no titles were announced after Andrew Cartmel's Atom Bomb Blues, which was released in November 2005.In a talk in July 2006, commissioning editor Justin Richards said that BBC Books have plans for the future of the Past Doctor Adventures, but that decisions had not yet been taken.
