The e-book with more than 600 pages is the result of the EU project "Volunteers4Europe", which was carried out from 2018 to 2020. In this project, teams from Estonia, France, Germany, Italy and Sweden documented interesting examples of volunteering in their country. The results were also presented to the public through international exhibitions. The project was co-financed by the European funding programme Erasmus Plus. The e-book gives a comprehensive impression of the multifaceted nature of volunteering in Europe.
