Although the Iroquois are one of the most thoroughly studied Indian peoples of this continent, many important aspects of their history and culture remain unexplained. For the past 20 years the Conference on Iroquois Research has reported on current research and discussed needs and opportunities for future research. Twenty papers are included in this document. These deal with such subjects as aspects of recent change on the Allegany Reservation, early years of the Seneca nation, etymology of the word "Iroquois," the Onondaga Bowl Game, and acculturation on the Tyendinaga Reserve in Canada. Another paper suggests the Huron and Iroquois may not have had as strong a matrilocal rule of residence in the 17th century as previously believed. Interest by the Tuscaroras to revive their language is also discussed. An ethnohistorical study of Hocheloga made in connection with the restudy of the Dawson site is given, as well as a discussion of some hitherto unreported pottery types in Eastern Ontario and Southern Quebec. Five papers report on archaeological work at the Kelso, Howlett Hill, Garoga, Simmons, and Cornish Sites. Three reports are concerned with other aspects of analysis and interpretation of archaeological data; these deal with pottery analysis in terms of "attributes" rather than types, pottery analysis as a source for inferences on social relationships and organizations among the Straits of Mackinac peoples, and the use of ethnographic data to interpret archaeological data from the Mohr site. The final paper deals with the Anthropology Study Curriculum Project. History and purposes of the Conference on Iroquois Research are also given. (Author/DS)
