Further, the book illustrates the basics of corpus-linguistic methods and demonstrates the use of a vast range of freely available corpora suited to the study of sociolinguistic variation and change.With its in-chapter exercises and discussion questions, and online supplementary resources, this text is key reading for students and researchers of corpus linguistics and sociolinguistics.
