The Encyclopedia is divided into three parts. The first contains case studies, by leading experts, of over fifty hunting and gathering peoples, in seven major world regions. There is a general introduction and an archaeological overview for each region. Part II contains thematic essays on prehistory, social life, gender, music and art, health, religion, and indigenous knowledge. The final part surveys the complex histories of hunter-gatherers' encounters with colonialism and the state, and their ongoing struggles for dignity and human rights as part of the world-wide movement of indigenous peoples.
