(2/2) I also found the same material was reused and updated for two further books by the author. The next was in 1983 - "Fifty Facts About Robots". While the Daleks are still called robots, the Cybermen have been updated with a drawing of two 'Revenge of the Cybermen' style! (Although the left hand Cyberman does look a bit iffy!) And in 1985, "Just Look At... Robotics" the entry about Daleks being robots has gone! (Hurrah!) And for the Cybermen there's a photo from Earthshock. #doctorwho #cybermen #daleks
