ABSTRACT
Over time, the handbook has been constructed as a key genre within each area of academic research. Handbooks are expected to provide a broad mapping of the tides and rockpools emerging across each area. Over the last 30 years, there have been major changes of an ontological and epistemological nature in sociolinguistic and socially oriented applied linguistic research on multilingualism, as different intellectual tides have come and gone across the social sciences and the humanities. So, there has been quite a lot of mapping to do in the first and second editions of The Routledge Handbook of Multilingualism.
