There are a number of useful sites out there that attempt to narrate the history of cognitive anthropology and/or delineate its various dimensions. From what I can tell so far, maybe the field has never been quite big enough for the kind of abstraction that narration or delineation usually require. It seems like, in my reading, a remarkable collection of individuals who were loosely allied by principle but not so much by methodology. (Strikingly similar to folklore studies in that regard, I think.)
