The Cambridge Encyclopedia of Anthropology (CEA)
As a PhD student I developed the idea of an OA encyclopedia of anthropology. The idea received generous support from Cambridge colleagues, and from the Wenner-Gren Foundation, which is why you can now find it here: www.anthroencyclopedia.com
Co-edited by Sian Lazar, Matei Candea, Hildegard Diemberger, Joel Robbins, Andrew Sanchez and Rupert Stasch, the CEA is an online book that grows continuously, via peer-review. Its goal is to facilitate access to scholarship in Social Anthropology for experts and non-experts worldwide.
I personally also consider the CEA to be an experiment in opening up encyclopedic writing to authors from around the globe. I am keen to find out which topics they will suggest and how they will approach them.
