May

 * 18 - Doctor Who - The Nightmare Fair First Published. This is the first of a new spin-off line by Target Books dubbed "The Missing Episodes". These are novels based upon the cancelled Season 23, which was delayed a year due to the BBC-ordered hiatus and which ultimately was 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 is the lead character.

June

 * 15 - Doctor Who - Mindwarp First Published. This is the fourth and final novelisation based upon segments of The Trial of a Time Lord.

July

 * 20 - Doctor Who - The Chase First Published. Written by John Peel, The Chase was the first of a series of Dalek story novelisations by Peel that were commissioned after Target Books reached an agreement with Terry Nation that would allow his remaining Dalek stories to be adapted as novels. (Prior to this, The Chase, and other Nation-penned Dalek episodes, were expected to remain in limbo, novelisation-wise). Around the time of this book's release, it's announced that a similar agreement had been reached with Eric Saward regarding his two Daleks serials, but ultimately these two stories were never adapted.

 * 23 - Sylvester McCoy records the monologue that ends episode 3 of Survival and, ultimately, the original 1963-89 Doctor Who series. This is a late addition to the serial by John Nathan-Turner, who expects it to be the final episode. Ironically this is also the anniversary of the debut of Doctor Who in 1963. It's also one of the few times since the 1960s that a major element of a televised serial is produced while the serial in question has already begun airing.

At some point shortly before broadcast, John Nathan Turner is informed of the BBC's decision not to continue the series and has Sylvester McCoy record a series-ending monologue that plays at the end of the episode. Final 25-minute episode produced. Despite this, it is still widely assumed by fans and cast after the episode airs that a new season would air in 1990.


 * 12 - Howard Lang, who portrayed Horg in "An Unearthly Child," dies.


 * 21 - Doctor Who - The Greatest Show in the Galaxy First Published. The title of this release ends up being ironic, as it becomes the first Target Books novelisation to be published after the de facto end of the original 1963-89 series.


 * The Doctor Who: The Scripts release of The Daleks first published. The next release in this series would not occur until 1992.

Unknown dates
