 * 17 - Target Books follows up its successful 1973 re-printings of novelisations from the 1960s with the publications of its first newly commissioned adaptations, Doctor Who and the Auton Invasion by Terrance Dicks, based upon the Third Doctor serial Spearhead from Space, and Doctor Who and the Cave-Monsters by Malcolm Hulke, adapting Doctor Who and the Silurians. Auton Invasion would be the first of many Doctor Who novels written by Dicks over the next 30-plus years and Target would continue to novelise Doctor Who adventures for the next 20 years. Doctor Who and the Auton Invasion also marks the start of a long and prolific association between Dicks and the world of Doctor Who printed fiction; over the next 35 years he would go on to write not only the lion's share of Target novelisations, but also contribute to most of the later lines of spin-off continuation fiction.
