Cambios

A wiki format has been chosen as it will allow expansions in the long-term and create links between the content considered separately according to the themes, but interrelated. And graphic material can be included that has been discarded in each volume for reasons of space and budget.

Another new feature is that summaries of each chapter in three languages – English, French and Basque – are included alongside the full version in Spanish.
