I liked the beginning; what came after was a hodgepodge running in circles from Eastern seaboard to Brazil to Peru and back again, all the while neglecting areas northwest and Southwest of Central Mexico and South of Mexico in North America and neglecting Northern parts of South America. The books seemed to be hit and miss, with no indication of the intellectual background of the journalist; some ethnology, some archeology, some prehistory, some travelogue, some guessimations of psychology. If he had a good editor, he'd have been able to get twice the information in on half the pages. Footnotes were assigned page numbers (no note numbers); what academia teaches these days I know not.
