This issue of Language in Society has been designed to explore the relevance of the concept of Community of Practice (CofP) – as presented by Lave & Wenger 1991 and by Wenger 1998 – to research in sociolinguistics, with a particular focus on its value in language and gender research. The contents of the issue grew out of a symposium at the Sixth International Conference on Language and Social Psychology, held at the University of Ottawa in May 1997. I invited the contributors whose work is represented in this issue to join me in exploring the usefulness of the CofP framework in relation to their own research.
