[Excerpted from Introduction]: In this chapter I review research on multilingualism in societies and communities from a sociolinguistic perspective and provide examples of some recent studies and trends. Among the themes to be discussed, such as language shift, language policies, and language use in media, I foreground studies examining multilingualism in various linguistic landscapes and virtual/online spaces, reflecting the large amount of research on these topics at present and their social significance. I then describe the research methodologies that have been use and gaps in current work, before concluding the chapter.
