a behemoth undertaking ... a suitable textbook with a copious amount of captivating language-oriented examples and illustrations for students not yet familiar with studies concerned with language and society.
Tyler Barrett, Australian Review of Applied Linguistics
Professor Simpson's book is one of the best introductions to sociolinguistics to come out in recent years, and exactly the kind of textbook that I was hoping to assign to my students. It is extraordinarily comprehensive, with a wide range of topics explored thoroughly and illustrated with case studies and examples from across the world and from many linguistic contexts. It is a truly global textbook. Perhaps most significantly, the book opens with chapters of multilingualism and language contact, establishing these as central to sociolinguistics, and this focus on multilingualism is sustained throughout the book, which is a very refreshing and long overdue approach.
