Spoilers are precisely defined here. Rules vary by the story's medium. Info from television stories can't be added here until after the top or bottom of the hour, British time, closest to the end credits roll on BBC One. Therefore, fans in the Americas who are sensitive to spoilers should avoid Tardis on Sundays until they've seen the episode.
Initially, the novels were not linked to Virgin Books' previous Doctor WhoNew Adventures line, but as the series progressed, the barriers began to come down; as a result, many EDAs contain characters and references to events in the Virgin series.
While the EDA novels did not contain sexual or "adult" content as explicit as the Virgin series, they contained better (if sometimes subtle) representative themes, implications, and even blatant statements that gave major characters a degree of sexual or gender ambiguity and expression outside of heterosexuality and cisgender identity, including Sam Jones, Fitz Kreiner, and most notably the Doctor.
With more than seventy novels published, the Eighth Doctor Adventures is the longest-running series of novels featuring any single incarnation of the Doctor to date.
In 2005 BBC Books retired its EDA and PDA lines, preferring to focus its publishing efforts on novels based upon the revived TV series. Although there was speculation that the Eighth Doctor's adventures might continue in a revived PDA line of books, this did not occur. The literary adventures of the Eighth Doctor continued in the Short Trips short story anthologies published by Big Finish Productions (many of which were written by veterans of the EDA and PDA ranges), until that series was also retired in the spring of 2009. BBC Books and Puffin have included the Eighth Doctor in various short story series and collections since.
