BBC Past Doctor Adventures

The BBC Past Doctor Adventures was a series of paperback novel releases by BBC Books, launched in 1997 in conjunction with its Eighth Doctor Adventures line. The line featured new adventures of the first seven Doctors, with the exception of two releases: The Face of the Enemy, featuring the Master; and one of the last novels, Fear Itself, which was the only PDA with the Eighth Doctor in a lead role, following the Ninth Doctor's debut on television.

The Past Doctor Adventures novels were released on a regular schedule by BBC Books: monthly from the range's launch in June 1997 until August 2002, and bimonthly from September 2002 until the series' end. There were only three exceptions in the line's otherwise-regular release schedule: November 1998, when The Infinity Doctors was published in the PDA release slot despite not being classified as such by BBC Books; August 1999, when both volumes of the multi-Doctor novel Interference were published; and February 2004, when Scream of the Shalka, a novelisation of the webcast of the same name, was released, pushing back the next PDA into March.

Both the PDA and EDA lines ended in late 2005 when BBC Books decided to focus its publishing ventures on books related to the revived TV series. However, there have been numerous "adventures involving past Doctors" published since the advent of the BBC Wales era. The Short Trips series of short story anthologies and the annual standalone "deluxe" hardback novel line that began with The Wheel of Ice are two examples of regularly released book lines featuring a Doctor not currently featuring in the television series.
