Suresh Canagarajah, Penn State, USAI am of the view that this book will be an important publication in the fields of applied linguistics and sociolinguistics to further our understanding of language diversity in our globalizing world.. The editors succeed in showing the need for the handbook and the way it carves its own niche in the market.He had a few very constructive suggestions, including adding a section on education, which I am discussing with the editors.John Gray, Univ of East London, UKA handbook at this stage would be an invaluable resource, given this proliferation and indeed recent critique of the concept... Such a volume would also sit well in the Applied Linguistics series, given the centrality of language in work on superdiversity.. There are many strengths – the involvement of a team of already recognised scholars of international standing; the interdisciplinary focus and the centrality of language are all noteworthy.Main suggestion was to add a section on education, as SC above. This does reflect the background of both readers but it is clearly important.
