Last year (2020) I was invited to write a chapter on infrastructure for the International Encyclopedia of Anthropology. The totality of this burgeoning field stretches well beyond the scope of my awareness, and I’ve probably left out several important gems, as well as the most recent research. In this piece I draw together a few of the approaches, themes, and questions that I find most exciting, while simultaneously cover some degree of variety in anthropological and STS approaches. The chapter also includes a fairly long bibliography for those seeking recommendations on further readings. Access the text here or download a pdf.
