'In this important volume Anna M. Babel brings together scholars drawing on diverse methodologies (ethnographic, experimental, elicitation/interview) to demonstrate how themes of awareness and control that have been a central concern in the history of sociolinguistics have wide-reaching implications for integrating sociolinguistic research with sub-fields of theoretical and applied linguistics, and for interdisciplinary engagement with cognitive science, social psychology, and anthropology.'
