releasing further unabridged audiobooks of the Target novelisations at a regular rate. An Unearthly Child was set to receive a new novelisation exclusive to audio, read by William Russell, written by Nigel Robinson, and released by AudioGo. The audiobook was originally scheduled to be released November 2013, but the release was cancelled due to AudioGo's bankruptcy. After being rescheduled for a November 2014 release and then pulled from the schedule, rights issues are currently preventing its release. Pearson Education Pearson Education published adaptations of four Eleventh Doctor stories in 2011 (two of which were photnovelisations) and six Twelfth Doctor stories in 2018 for use in schools. Publication details Writing Although Target endeavoured to commission the original scriptwriters to novelise their own stories, this was not always possible. As a result, many books in the Target line were written by Terrance Dicks. During the late 1970s to early 1980s, Target, which classified the novelisations as children's fiction, imposed a page limit of 128 pages. Some books (particularly several by Dicks) even fell short of this limit. By the late 1980s, however, the page cap had been lifted, although John Peel was still required to split his novelisation of the epic 12-episode The Daleks' Master Plan into two volumes because the manuscript was too long. Titles For the first few years of the Target line, it was common practice for the novels to have titles that differed from the adapted serials: for example, Doctor Who and the Auton Invasion, which was based upon the serial Spearhead from Space. This practice was dropped in the mid-1970s. Another tradition established by the books was to prepend the words "Doctor Who and ..." to the titles, except in a few cases where impractical. This practice continued until the early 1980s. From 1990 onwards reprints of the books generally dropped "Doctor Who and..." from the title and changed titles back to the original television story, although some of the reprints merely rejacketed earlier stock. Illustrators The first of the Target reissues featured new cover artwork by Chris Achilleos, who went on to illustrate over 30 of the novelisations throughout the 1970s. British artist Andrew Skilleter created much of the cover art from 1979 to 1994, along with video covers and other merchandise. His work on Doctor Who was showcased in his 1995 volume Blacklight: The Art of Andrew Skilleter. Numbering Target began numbering its novelisations from
