Mercedes Durham is Lecturer in Sociolinguistics at Cardiff University. Her research interests include sociolinguistics, language variation and change, English as a world language, dialects of English and the acquisition of variation.

This is a most interesting book and offers lots of new insights into language variation and change, the role of new technologies in the evolution of language use, new speech 'communities' of multilingual speakers and also further explorations of the relationship between SLA and sociolinguistics which add to those already in existence. In addition, there are interesting implications for language teaching and learning.
