Many works have been written on scouting worldwide, but most of them were centered in a particular country or moment of history. This book explains in a very comprehensible way the main characteristics of world (boy and girl) Scouting, the largest youth movement in the planet, gathering 30 million people in more than 165 countries of the five continents. Using new data and storytelling, the work covers the main elements that distinguish the scout movement over the world, and explains its origin, evolution, operating system, and the soundness of its values.
