The Big Finish Short Trips volumes are produced in a slightly different manner from their BBC predecessors: instead of being centrally produced, Big Finish commissions editors for the volumes, who in turn commission stories from writers for the themed collections.
[2] Each collection is conceived around a single theme, with the individual stories exploring that theme: The collections have mixed established Doctor Who writers from the television series, such as Ben Aaronovitch, Ian Briggs, Andrew Cartmel, Terrance Dicks, Glen McCoy, James Moran, Marc Platt, Helen Raynor and Eric Saward with writers who made their name in other Doctor Who spin-off ranges, such as Paul Cornell, Joseph Lidster, Kate Orman, Lance Parkin, Philip Purser-Hallard, Gareth Roberts, Gary Russell and Robert Shearman, and writers from other literary spheres, including Dan Abnett, Lou Anders, Scott Andrews, Jonathan Clements, Peter David, Richard Dinnick, Keith R.A. DeCandido, Brian Dooley, Diane Duane, Nev Fountain, Lizzie Hopley, Todd McCaffrey, Juliet E. McKenna, Paul Magrs, James Moran, Gary Owen, Stel Pavlou, Steven Savile, James Swallow and Matthew Sweet.
On 10 February 2010 Big Finish announced that the range would be relaunched as double CD audiobooks featuring eight new short stories each.
Also on this day Big Finish asked for short story submissions, from anyone who hadn't written for them before, for possible inclusion on the CDs.
Starting from September 2016, Big Finish is releasing these exclusives to general customers under the banner, Short Trips Rarities.
