  Katy B\"orner has written a wonderful book about visualization that makes our
field of scientometrics accessible to much larger audiences. The book is to be
read in relation to the ongoing series of exhibitions entitled "Places &
Spaces: Mapping Science" currently touring the world. The book also provides
the scholarly background to the exhibitions. It celebrates scientometrics as
the discipline in the background that enables us to visualize the evolution of
knowledge as the acumen of human civilization.
