In this volume, sixteen distinguished scholars address the impact of digital technologies on how anthropologists do fieldwork and on what they study. With nearly three billion Internet users and more than four and a half billion mobile phone owners today, and with an ever-growing array of electronic devices and information sources, ethnographers confront a vastly different world from just decades ago, when fieldnotes produced by hand and typewriter were the professional norm. Reflecting on fieldwork experiences both off- and online, the contributors survey changes and continuities since the classic volume Fieldnotes: The Makings of Anthropology, edited by Roger Sanjek, was published in 1990. They also confront ethical issues in online fieldwork, the strictures of institutional review boards affecting contemporary research, new forms of digital data and mediated collaboration, shifting boundaries between home and field, and practical and moral aspects of fieldnote recording, curating, sharing, and archiving. The essays draw upon fieldwork in locales ranging from Japan, Liberia, Germany, India, Jamaica, Zambia, to Iraqi Kurdistan, and with diaspora groups of Brazilians in Belgium and Indonesians of Hadhrami Arab descent. In the United States, fieldwork populations include urban mothers of toddlers and young children, teen tech users, Bitcoin traders, World of Warcraft gamers, online texters and bloggers, and anthropologists themselves. With growing interest in both traditional and digital ethnographic methods, scholars and students in anthropology and sociology, as well as in computer and information sciences, linguistics, social work, communications, media studies, design, management, and policy fields, will find much of value in this engaging and accessibly written volume.
