This companion volume to The Programme Guide contains everything there is to know about Doctor Who and the planet Earth. The information is divided into three main sections. The first contains a Who's Who of the actors, technicians and writers connected with the Doctor Who television stories. The second contains brief details of all the Doctor Who adventures other than those shown on television - the stories from the stage plays, the radio programmes, and the comic strips. The third is a chronology of Earth History as revealed in the Doctor Who television stories. The Terrestrial Index is packed with information for Doctor Who fans, and is an indispensable companion to The Programme Guide. The third volume of Jean-Marc Lofficier's Doctor Who reference trilogy will be entitled The Universal Databank.
