The single greatest work in the history of Econological research is available on line. Life Among the Econ by Axel Leijonhufvud is available here. This is a must read for anyone who wishes to understand the vast bleak and dismal territory that the Econ tribe occupies in the far North. It is one a the very few studies that tries to understand the social structure and ways of life of the Econ tribe. The information that we do have indicates that, for such a primitive people, that social structure is quite complex but this information is fragmentary and not well validated. Further study is much needed.
