• 24 - DWN: Doctor Who - Enlightenment was first published. A rare occasion where more than one novelisation has been published at different times within the same calendar month. Second and last use of the modified logo-and-photo branding for a Fifth Doctor novelisation, and the final use of a photographic element on a Doctor Who fiction book until the 1988 novelisation of DWN: Time and the Rani. As Target was not allowed to feature artistic renderings of Peter Davison at the time, this was the last appearance of an image of the Fifth Doctor on a new novelisation, although Target would finally be allowed to feature drawings of Davison when it issued new editions of many of its novelisations in the early 1990s. Target subsequently chose not to include images of the Sixth Doctor on initial releases of any of that era's novelisations; therefore, an image of the current Doctor would not appear again on the cover of a newly issued Target novelisation until DWN: Paradise Towers was published in December 1988.
