These were novels based upon the cancelled Season 23, which was delayed a year due to the BBC-ordered hiatus and then replaced by what became The Trial of a Time Lord. Although based upon a teleplay, the fact it was never produced makes this, in effect, the first original-to-print Doctor Who novel in which the Doctor himself was the lead character.

 * Unknown - Pioneer Books published the second edition of The Doctor and the Enterprise by Jean Airey. An unauthorised crossover between Doctor Who, Star Trek, and The Wizard of Oz, the book had previously been published in a small-press edition in 1982; this new version edited out most overt references to Star Trek character names.
 * Unknown - The first edition of the four-track EP, Doctor Who - Variations on a Theme, was released in twelve-inch vinyl, standard CD, and as an unusual square-shaped CD. This release featured unique rearrangements of the Doctor Who theme by Mark Ayres, Dominic Glynn, and Keff McCulloch that had been created for various Doctor Who Appreciation Society conventions in the 1980s. One of these, the "Latin Version", was later adopted by BBC Video as the theme for its "Years" series of video retrospectives.
