Book excerpt: In parts of the world where Christianity and indigenous practices have been integrated into hybrid religions, the advent of the new millennium produced an immense stir. "Millennial Countdown in New Guinea" provides a unique set of studies based on recent fieldwork that deal with perceptions of the new millennium in New Guinea. The articles collected here represent a rich ethnographic record of events leading up to the new millennium, exploring "end times" versus "new world" notions among New Guinea societies. Unlike other published collections on New Guinea, this special issue of Ethnohistory focuses on the entire island, with essays on both Irian Jaya and Papua New Guinea. It makes a distinguished contribution to a classic theme in anthropology and the history of religion.
