Robin Fox 
The Keresan Bridge [EPUB ebook] 
A Problem in Pueblo Ethnology

This is an unusual excursion into American Indian culture history by a British social anthropologist. It examines theories of the development of different Pueblo social structures, with particular attention to Eggan. From a detailed re-analysis of the evidence and a consideration of material from the Eastern Keresan Pueblo of Cochiti, based on his own fieldwork, Dr Fox concludes that the theory that all Pueblos were derived from a common base is no longer tenable, and that a diversity of origins is more probable. Apart from its contribution to Amerindian studies, the book is of particular interest as an approach to modern culture history by a social anthropologist.
