Doctor Who script books

During the history of the Doctor Who franchise, a limited number of teleplay scripts have been commercially released. These have ranged from teleplays taken from the original 1963-89 TV series, to scripts from the 2005-present revival. Big Finish Productions has published several volumes of scripts taken from its ongoing line of audio dramas. And to date two books featuring three teleplays from unproduced stories have been published, all featuring abandoned First Doctor stories: The Masters of Luxor, Farewell Great Macedon, and The Fragile Yellow Arc of Fragrance; the latter is a single-episode script included in the same volume as Farewell Great Macedon. One script book, for the unbroadcast (but partially completed) Shada was also published with the UK release of a video of the story.
