The author focuses primarily on economic interaction networks and specialised crafts to show how they can provide a window on the other changes that may have been occurring.

This paper discusses some theoretical questions and present some observations on the role of ethnoarchaeological studies of craft production in contemporary stratified social contexts, in the study of protohistoric societies.

The author's research on the understanding of specialized crafts and the trade/exchange between rural and urban sites combined with his recent ethnoarchaeological studies has led him to question some of the generalizations that are prevalent about craft specialization and socio-economic organization of the Indus Civilization.

Findings from the third season of research by the University of California, Berkeley, project at Harappa, conducted from January 1 to mid-April 1988.
