World Leisure, an international organization devoted to the scientific study and promotion of leisure, has as part of its structure several commissions devoted to matters consistent with this mission. One of these – the Volunteerism Commission – was founded to organize and encourage research in all countries on all aspects of volunteering that relate to leisure and, to the extent they are deemed useful there, to disseminate to the applied sector the world over relevant research findings in this area. The socio-economic context of leisure and volunteering is explored and a case made for viewing volunteering as leisure activity. The structure and programs of the Volunteerism Commission are then examined. A selected bibliography of theory and research in this area is presented as part of the reference list.
