Mind Alive is a new kind of encyclopedia that is published in 120 weekly Parts and builds week by week into a complete eight-volume work of reference.
Text in italics taken from the inside sleeve of the 1968 Marshall Cavendish Publication Mind Alive. A friend of mine recently came across a large number of these and very kindly passed a few of them on to me. 3'6 which if I remember right is seventeen and a half pence. Bargain!
