The additional steps on the road toward Proto-Amerindian presented in this volume should come as no surprise to those whose speculations on the subject based on scattered observations have been presented from time to time. That the authors of this work should be members of the Summer Institute of Linguistics likewise should not be surprising. With linguistic teams working in over 285 languages in North and South America, a growing corps of consultants in linguistics and anthropology, and a workshop program for pooling information and writing up results, members of this organization have contributed and will continue to contribute substantially to American Indian linguistics.
