The field of ethnography seems to be a strange cross between anthropology, psychology and sociology: all of which are attempts to understand the ways in which humans interact with each other in a society. For the field of language and literacy, the team of Shirley Brice Heath and Brian Street make an effective co-authoring team (while taken individually they can be a little two much). Especially good news for Molly Mills, whose off-the-beaten-track research project got so attention from both authors that they structured their book around her juggling participant, Roger.
